My subjective feeling was backed up by your testing. I feel validated! Lol. I also have had some UI problems, but Vulkan let's me play at 2k with the clouds on high vs 1080p with clouds on medium so I'm running it in 3.23 despite the memory leak.
I'm lucky enough to be able to play on highest settings without vulkan with a 4090 but would have liked to see if it offered improvements in Draw distance etc... that I've heard about. Unfortunately it does not support HDR. That is huge. If you have an OLED and run HDR in any space game, you can't possibly give up that for any amount of performance. It literally makes the game IMO. OLED and space blacks are gorgeous. SC is the only game I play outside VR atm, and my monitor was literally purchased to play SC. 4k 48" OLED and head tracking (and sitting too close) is awesome. Bring HDR (and please VR) to SC and I'll change my mind on vulcan.
When I upgraded a few years ago from an i7-5820k to an "old" i7-6950 Extreme I immediately noticed how much smoother the gameplay was... Despite the fps staying around the same. Running 4090 on both setups.
@@JM-jd2bf at least you didn't say what many have parroted... "It's an obsolete CPU, why not buy an i9 or XD3d ?" 😆 The 10 core 20 thread, 40 channel Extreme is overclocked from 3ghz to 4.1ghz. It only cost $318 cdn delivered. ($2300 when new in 2016) Best chip I could get for the X99 Dlx mobo. The CPU and 4090 (64GB ddr4 @ 3200) are driving three (3) x 28" 4k screens in StarCitizen. Last night I was seeing highs of 62 and lows of 25 in Lorville. 3.23.1 LIVE. Looking forward to Vulkan when they include Multithreading support.
Same results here with my Laptop aswell. More will come with Multithreading and optimisations, probably. I've also made a combination with Lossless Scaling and it's pristine ! Smooth like butter with a little input lag though...
That hasn't been my experience. I'm on a i7 8700k, 32GB RAM, GTX 1080, and I had significantly worse performance at cities. I'm definitely GPU bound so this isn't that surprising given what we have heard from CIG on the whole gen12 renderer upgrade.
Vulkan works great for me in cities/space, but then when I go planetside for bunker missions etc it grinds to a slideshow. Sticking with DX11 for now I guess.
I had the same issue on both DX11 and Vulkan--what solved it for DX11 was turning down my graphics quality to high from very high. I haven't tested the same for Vulkan but I'm hopeful it'll work.
I've run the game on vulkan and didnt notice anything but a lower average loss of 20 fps. Even DLSS doesnt seem to do anything for frames in my testing. Like Im running a 4090, both of these should gain some form of fps improvement if they worked correctly. lol sticking with dx11
Turned off Vulkan last night. Noticed some hitching a little but I didn’t have any major stalls like I had with Vulkan going. I did only a simple bunker mission which did have some moderate freezing, which caused the npc’s inside to move suddenly around the bunker. This allowed them to get some shots off at me but the npc’s were more responsive. I can see once some of these issues are smoothed over, that the npc’s in bunkers will be more challenging due to being more responsive.
I really prefer Vulkan just because of the low's reducing the micro stuttering that I've dealt with using DirectX. That being said the MFD and bloom issues make it difficult to play with Vulkan.
I load into a black screen when I use vulkan, and I can't even alt+F4 the game - it forces me to open task manager and then I get control over that screen again. In Siege or BG3, when I enable vulkan the game just crashes instantly. Have literally never gotten vulkan to work and idk what the issue could be
To change the native resolution on fly with Vulkan, you need to change the desktop resolution. Then alt+enter windowed mode and back to native resolution to apply settings.
I'm super hopeful for vulkan in the next major patch. I'm surprised that they added vulkan so fast after only showing a wall on citcon. I thought it's only gonna be added around September.
Glad to see everyone enjoying the implementation of Vulkan, I must be the exception of the rule because when I opted in for Vulkan I got my FPS cut in half (from 40-60fps to 15-20fps) when I entered the same server in loreville and got my fps back when I opted out of vulkan; did not look what could cause the problem, but a friend of mine had the same bug he had in PTU where he couldn't play when he opted in vulkan

I don't think there is a "VRAM leak", I think it's just that Vulkan allocate stuff in memory differently than DX11. While on Vulkan the game use more VRAM, it also use less RAM than on DX11. Keep also in mind that loading something from RAM take significantly more time and energy, than loading it from the VRAM to the GPU that are directly next to each other. This also would explain the more consistent frametime, since everything the game and the GPU need, is just store next to it in the VRAM instead of the very far away RAM.
Would like to see some AMD GPU results, usually AMD is very strong with Vulkan. I find Vulkan is much smoother especially at first login, it seems the optimization of shaders helps fix some of the stutteriness of dx11
Your Frametime spikes are becasue of the 7800X3d. Every time a draw call misses the 3d Cache, it has to page your RAM. Which is when the spikes happen. Vulcan memory management of the asset is a lot better - which is why you get a small improvement in the 1% lows.
Fun fact is that vulkan improves reflection, fog effect, ray marching or whatever it is called, tyndall effect and many more. Note : but for some of these we can't even notice if we try to do a close look. More noticeable is reflection.

Have a ryzen 7 3700x/3060TI/32GB ram, 1080p. Vulkan on with Dlss set on quality is super smooth, less stutters and mostly 60 fps in all areas, have the game on low but it’s running significantly smoother for me than dx11. I have noticed an issue though where sometimes my frames will go down to like 16fps randomly after running the game for awhile and be locked there no matter what I’m doing. I have to go into the game settings and turn scaling off then back on to fix it.
This seems to make sense, as I played for several hours the other day, but the last hour produced a steady frame drop. Vulkan was enabled, and I run a ryzen 5 3600 with a 6700xt and 32 gigs of RAM.
Been really impressed framewise so far. 7800x3D & 4090. 4k dlss quality, all settings high and Vulkan on. Been seeing around 50-80fps in all cities, mostly sitting at 65-70. Space and atmo flight is anything between 80 and 170fps! Bonkers. I'll still switch back to dx11 for now. Haven't tested that yet.
Great testing! My experience is that I would get generally good to great performance but then it would just drop down to sub 20 and never recover until I turned off DLSS and turned it back on. DX11 is more stable in that regards but I long for when I can set Vulkan as the default renderer. That said I'm on a 10GB card so maybe that's when my vram is conking out.
i had issues with the Ui in the EPTU but in live this seemed fixed and it feels way snappier as DX11 on my R7 7700x + RX6800xt; also i haven't noticed any VRAM issues yet
Personally been hopping back and forth. Feels like they both have benefits and drawbacks, possibly directly related to Vulcan being more cpu heavy while being easier on the GPU and vice versa.
any of you having that issue with vulkan where the FPS stays locked at arround 20fps after a couple of minutes into the game(places where i get 90+ FPS with DX11)
I tried it and while I was in Area 18 it worked flawlessly and everything looked absolutely gorgeous. I was totally sold but then I decided to go to Wala... It was an unrecognizable mess. I went back to Direct3D11 and haven't had any issues. I think Vulkan once ready will definitely be the way to go but sadly it's not quite there yet. I will definitely try it again once they sort out some of the issues.
Vulkan certainly felt smoother. It did, however, also break reshade, even after switching to the latest version and installing it with Vulkan selected. It also has an issue running borderless as it shows a part of the desktop on the bottom anyway
You have a 16GB VRAM card. So the game using it as good a possible, when running longer - keeping textures and shaders it encounters during your "runs" in VRAM instead of loading them again later - would be a good thing. It should only unload data, once it is running out of VRAM. So this could, but must not mean a memory leak.
i have'nt tried vulkan yet but i noticed a big reduction on ram resources and i believe it could be pretty playable for the people with 16gigs, i believe would be a nice idea to compare ram difference 16-32gigs in 3.23 and the same with some older version of sc to see the gap in performance if it got better or not, really nice video as always :)
You can’t use Vulkan because the devs disabled multi threading support, and also, there’s no HDR support. Nightmare for OLED panels. The one thing that Vulkan does fix, is that it fixes 16gb of ram performance drops after returning to a main city.
For the fullscreen problem: You have "Native Fullscreen" selected, which obviously uses the Native resolution. With that option selected, the resolution doesn't (or shouldn't?) do anything.
I've noticed the same thing, seems much smoother visually and I don't have very long play sessions, so not woried much about memory leak. I will keep it on for now.
My Vulkan worked really well in the EPTU (+10frames) but in Live I tried to load it up a few times but it loads shaders for well over an hour and runs at 2-3fps
Vulkan improves stuttering by quite a lot, but too many memory leaks for now. But it's beta and considering it still doesn't have multithreading enabled, I'm excited for the next release.
The problem with the Vulkan implementation right now its only a single thread rendering as opposed to the API's multithreading capabilities. For a basic explanation imagine trying to push 5000 objects through a narrow doorway, eventually youll get there but its slow. Now imagine pushing those 5000 objects through 8 seperate doorways, its a lot faster and smoother.
It's adressed in the video, but I personnaly find it more hopeful than a problem : Vulkan has equivalent to better (more constant) performance compared to Dx 11 *without* multithreading Imagine 8 direct x guys pushing 5000 objects for 12 years, and then one vulkan fella comes in and pushes those 5000 objects at the same speed as the 8 guys but with one arm, I wanna see him try seriously
@floriakson Yeah I know, I was just giving a basic visualisation of it for others. Vulkan is a far superior API when utilised properly, I have absolutely zero doubts that when it's implementation becomes more akin to standard, performance will be far superior than what DX can provide.
for me with a 3080 Vulkan uses 2x the GPU power for the same frames. I lock my frames to 50fps and use Gsync @1440p. Overall the its ultra smooth with no load stutters. loving 3.23 so far
Great info, thanks! I always worry that the heavy single core processing will damage my system with this game. Might just be me being paranoid though...
As long as your cpu cooling is decent you should be fine! These modern cpus have a lot of safeguards to ensure everything stays safe. Unless you go wild in the bios you should be good!
I run 7800x3D, 7900xtx, 64gb ddr5 and vulkan has been butter for me but I haven't run in anything other than native mode (same as monitor) so I didn't run into the problem you mentioned and I have so much vram I haven't noticed any issues since I have plenty of overhead so.... Anecdotal.
just upgraded to a Ryzen 7 5800x running it with a RTX 2070 non super and 32gb of DDR4 ram. I have seen a 10-15 frame increase in performance from my Ryzen 7 2700 and much smoother performance overall using vulkan. I'll have to go back to direct X to see if the changes are consistent between the renderers and also check to see if your findings with a possible memory leak are consistent.
If you was trying to play this game on Intel Arc A770 16GB it was nearly Impossible to get good frames on dx11 and the micro stutters was insane unplayable and now with Vulkan i can play at 60fps on 4k native Resolution when using Lossless Scalings frame Generation
I've run the game on vulkan and didnt notice anything but a lower average loss of 20 fps. Even DLSS doesnt seem to do anything for frames in my testing. Like Im running a 4090, both of these should gain some form of fps improvement if they worked correctly. lol sticking with dx11
Yeah I found Vulkan to be super smooth, good frame times and a glassy feel. For some reason makes my OLED screen kick in its auto dimming so everything is really muted. Hopefully sorted out in a future patch as it seemed VERY promising
I have tried both Vulcan and Dx11 with a 3090 and 4k Alienware monitor. 3dx supports HDR, Vulcan does not yet (not available) I have found some artifacting with Vulcan periodically but it does run smoothly. I don’t see much difference between FPS between the two over a full play session. I have noted Vulcan does boot into the game much faster than 3dX11 Its interesting, but still needs some work

Just interested why you assume the higher memory usage is a "bug"? It could also be explained by the API keeping more assets loaded into video memory. I would like to see if there's a degradation of the performance after several runs without restart. Perhaps having the otherwise unused VRAM occupied could be a good thing? Also I've heard reports that Vulkan is crashing on AMD cards which is ironic as the technology was invented by AMD. I have an AMD card so didn't turn it on myself yet after reading these reports.
I personally use Vulkan simply due to the improved smoothness and reduction of stutters due to the shader precaching. Also, the Vram leak isn't really a hindrance on my machine because I'm using a 7900 XTX that has 24 Gigs of Vram and even after 3+ hours of playing the total Vram usage with Vulkan didn't go beyond 15 Gig. So it does seem to use more Vram over time compared to when you start the game but it isn't by much and it doesn't keep on climbing over longer playsessions.
Thank you for making this very informative video. In 3.23.1 using a 3080Ti and HD how would you make the graphic settings ( upscaling, upscaling techniques, and HDR) ?
I have had some pretty bad stuttering with vulkan, luckily with dlss set to 66% my 3060ti can push 45fps on orison at 3480 x 1440p and about 35fps with clouds set to high.
man, a 3060ti for a 27" monitor... ur GPU should suffer a lot ;) i have a 3070ti but on a 1080p (24" monitor) and always get 60 to 120 fps, huge difference
when i enable vulkan and try to enter the game, the "enter the universe" button is just not there for me for some reason XD guess im sticking with dx11 lmfao
I think 1% differences are more meaningful when the averages are so close. Exciting to see CIG optimizing performance. Maybe my 4080 will be my last GPU.
I found that Vulkan did not play nice with upscaling, it seems that might be fixed in 3.23.1, but I will await development further along before trusting it further
I find it a very weird implementation so far (I know it's not multi threaded yet), I'll get 50fps entering a bunker on ceiling, then 20 fps as I walk outside it. Other weird bits, if I have bad fps, then change the dlss mode to anything else, then back again, my fps will be back to reasonable.
Vulcan feels smoother for sure. I feel like the lighting is very different with 1080p highish settings some places are really dark. (11600fk+/3070/32GBDDR4/Evo970SSD) I haven't had any issues from the memory leak yet but maybe that is part of why my friends 40 series card wont run the game on dx12.
Vulkan seems to be better choice for cases when you have marginally enough vram on board. If less - Vulkan cause a massive fps drop after some playing time due to vram leakage. There is IC on that. So if you target 4k and have 3090 or 4080 and above you should be good to use Vulkan.
Considering that my RAM usage goes up to 36GB now, you might have even better results with more RAM. I'm messuring a 10% increase in FPS with Vulkan (up to 170). 7800X3D, 4070 Super, 48GB RAM, core isolation turned off
How's DLSS doing in the new patch? Did they fix the UI flicker issues from PTR? Now if only FG would be implemented, so many CPU bound PC would benefit from it... Although I was actually surprised about DLSS since many people said that this was going to arrive in years if ever.
VRAM usage might just be a different caching behavior. As long as you don't run into stutter when it approaches your maximum, it really doesn't matter how big that number is.
I played on 16 gigs of ram with vulken and it crashed so much. Swapped over to dx11 and it was so much more smooth. Just changed to 64 gigs of ram and vulken still feels a bit frame droppy compared to dx11 and i did notice memory leak when stress testing on vulken. Dx11 right now seems the way to go
Been using Vulcan ever since the option was available. I get lows of mid 20's to highs of mid 60 frames @ 11,520 x 2160 using 4090 set with a 90% power consumption limit.
Vulkan has been fine on my 2060 when I tried it but the real winner for me is DLSS Quality . The game feels so much smoother and there's a disinct improvement in visual quality in my eyes compared to native. I can finally turn the clouds on very high and not turn into a slideshow.
I hope Vulkan will be the default API in SC by the end of the year. We're in 2024. It's time to leave ancient DX11 behind for good. Having Vulkan also means we'll soon be getting real time ray tracing.
i have good perfs(60 to 120 fps) with vulkan on a middle range computer (i713700K with a 3070ti and 32GB of ddr5) and always use the defaut set by application i nvidia panel...any time im tried to set differents things using 3d settings it always cause problems from crashes to less perfs.
On my system (Ryzen 5 5600X, RTX 3070, 32 GB RAM, 1440p native resolution, DLSS enabled) I experience poor frame rates in Lorville while using Vulkan. While walking around it's around 20-25 fps and that's making me dizzy. I had much smoother frame rates in the same area in 3.22. Don't know why I'm experiencing this with Vulkan enabled.
Tried Vulkan, but no HDR is a hard no currently. On a 4090 my FPS is fine with DX11, and HDR is something I can't play without. When HDR support is added to vulkan I'll likely switch as the better renderer - and probably the renderer they will put the most dev time into in perpetuity.
My 3060 didnt like Vulkan. At all. Switched it over, relogged, loaded all the shaders, opened game and vid card started making pretty loud grumbling noises I have never heard before. Switched back to DX11 and no issues.
I've run the game on vulkan and didnt notice anything but a lower average loss of 20 fps. Even DLSS doesnt seem to do anything for frames in my testing. Like Im running a 4090, both of these should gain some form of fps improvement if they worked correctly. lol sticking with dx11

I am really enjoying it with an i9-14900KF and an RTX4090
With a 7800X3d and 4070 i defenetly felt that Vulkan was actually more smooth then DX11, i defenetly notice it.
Well in my case Vulkan just crashes the game on startup :/. I would prefer it though. Maybe a future patch or driver will fix it for me.
Always happy to see someone explaining the importance of frame pacing consistency not just average FPS

Way smoother using a 5900x/7900xtx with 32gb with Vulkan over dx. About fps I would say they were pretty much the same. More testing needed.
I got the feeling I got the leaking ram. But dx11 is much vorse. And Hdr is also weird. It can be turned on only when the game feels like it.

I have noticed an issue though where sometimes my frames will go down to like 16fps randomly after running the game for awhile and be locked there no matter what I’m doing. I have to go into the game settings and turn scaling off then back on to fix it.
This seems to make sense, as I played for several hours the other day, but the last hour produced a steady frame drop.
Vulkan was enabled, and I run a ryzen 5 3600 with a 6700xt and 32 gigs of RAM.
thanks for all this testing and data. appreciate it. love the channel. when the game is more perma imma send you some uec
Been really impressed framewise so far. 7800x3D & 4090. 4k dlss quality, all settings high and Vulkan on. Been seeing around 50-80fps in all cities, mostly sitting at 65-70. Space and atmo flight is anything between 80 and 170fps! Bonkers. I'll still switch back to dx11 for now. Haven't tested that yet.
In my short testing for some reason i also did see slightly higher average fps in dx11
Great testing!
My experience is that I would get generally good to great performance but then it would just drop down to sub 20 and never recover until I turned off DLSS and turned it back on.
DX11 is more stable in that regards but I long for when I can set Vulkan as the default renderer.
That said I'm on a 10GB card so maybe that's when my vram is conking out.
i had issues with the Ui in the EPTU but in live this seemed fixed and it feels way snappier as DX11 on my R7 7700x + RX6800xt; also i haven't noticed any VRAM issues yet
Personally been hopping back and forth. Feels like they both have benefits and drawbacks, possibly directly related to Vulcan being more cpu heavy while being easier on the GPU and vice versa.
any of you having that issue with vulkan where the FPS stays locked at arround 20fps after a couple of minutes into the game(places where i get 90+ FPS with DX11)
I tried it and while I was in Area 18 it worked flawlessly and everything looked absolutely gorgeous. I was totally sold but then I decided to go to Wala... It was an unrecognizable mess. I went back to Direct3D11 and haven't had any issues. I think Vulkan once ready will definitely be the way to go but sadly it's not quite there yet. I will definitely try it again once they sort out some of the issues.
Vulkan certainly felt smoother. It did, however, also break reshade, even after switching to the latest version and installing it with Vulkan selected.
It also has an issue running borderless as it shows a part of the desktop on the bottom anyway
You have a 16GB VRAM card. So the game using it as good a possible, when running longer - keeping textures and shaders it encounters during your "runs" in VRAM instead of loading them again later - would be a good thing. It should only unload data, once it is running out of VRAM. So this could, but must not mean a memory leak.
i have'nt tried vulkan yet but i noticed a big reduction on ram resources and i believe it could be pretty playable for the people with 16gigs, i believe would be a nice idea to compare ram difference 16-32gigs in 3.23 and the same with some older version of sc to see the gap in performance if it got better or not, really nice video as always :)
My experiance with vulcan is less about FPS but about getting a smoother framerate. Less hickups/framedrops and that feels good to me.
thanks for getting this out so quick after 3.23 went live. Vulkan is tempting but like you said best wait until the memory issue is sorted
You can’t use Vulkan because the devs disabled multi threading support, and also, there’s no HDR support. Nightmare for OLED panels. The one thing that Vulkan does fix, is that it fixes 16gb of ram performance drops after returning to a main city.
For the fullscreen problem: You have "Native Fullscreen" selected, which obviously uses the Native resolution. With that option selected, the resolution doesn't (or shouldn't?) do anything.
Thanks!
Thank you! The super thanks is very kind!
And thank you for becoming a member!
I've noticed the same thing, seems much smoother visually and I don't have very long play sessions, so not woried much about memory leak. I will keep it on for now.
My client won't start with Vulcan 😒 I have to revert it back to DX11 manually in a json config file. 6950xt.
My Vulkan worked really well in the EPTU (+10frames) but in Live I tried to load it up a few times but it loads shaders for well over an hour and runs at 2-3fps
Ever since 3.23 my planets arent loading textures and are just black (not using vulkan) anyone has the same issue?
I just found out on Hurston if you have vulkan on and go to pickers field when it loads the ai it CTDs
Vulkan improves stuttering by quite a lot, but too many memory leaks for now. But it's beta and considering it still doesn't have multithreading enabled, I'm excited for the next release.
I havent been able to use vulcan. Fans and vram wind out and game crashes within seconds.
On my laptop, map wouldn't show with dx11. With Vulkan it works normally, so I'm happy.
CapeframeX works in DX11. But when switching to Vulkan I cant get the overlay to display, any ideas?
Yeah I've heard a few people saying the same. I'm not having any issues, but I guess make sure riva tuner is up to date.
The problem with the Vulkan implementation right now its only a single thread rendering as opposed to the API's multithreading capabilities.
For a basic explanation imagine trying to push 5000 objects through a narrow doorway, eventually youll get there but its slow.
Now imagine pushing those 5000 objects through 8 seperate doorways, its a lot faster and smoother.
It's adressed in the video, but I personnaly find it more hopeful than a problem : Vulkan has equivalent to better (more constant) performance compared to Dx 11 *without* multithreading
Imagine 8 direct x guys pushing 5000 objects for 12 years, and then one vulkan fella comes in and pushes those 5000 objects at the same speed as the 8 guys but with one arm, I wanna see him try seriously
@floriakson Yeah I know, I was just giving a basic visualisation of it for others. Vulkan is a far superior API when utilised properly, I have absolutely zero doubts that when it's implementation becomes more akin to standard, performance will be far superior than what DX can provide.
@@geddybear9108I for one appreciate the analogy
Will vulcan someday use all of my cores
@michaelives5729 Yes, once parallel buffer generation is implemented it will use all your cores and squeeze as much performance as it can from them.
Being able to precompile alone on Vulkan is just so huge for stability. It's a shame HDR doesn't work.
for me with a 3080 Vulkan uses 2x the GPU power for the same frames. I lock my frames to 50fps and use Gsync @1440p. Overall the its ultra smooth with no load stutters. loving 3.23 so far
2:22 "stutters" is the word you're looking for 😂
I can't get hdr to work with Vulkan, is this normal ? Has it been mentionned anywhere ?
Great info, thanks! I always worry that the heavy single core processing will damage my system with this game. Might just be me being paranoid though...
As long as your cpu cooling is decent you should be fine! These modern cpus have a lot of safeguards to ensure everything stays safe. Unless you go wild in the bios you should be good!
I run 7800x3D, 7900xtx, 64gb ddr5 and vulkan has been butter for me but I haven't run in anything other than native mode (same as monitor) so I didn't run into the problem you mentioned and I have so much vram I haven't noticed any issues since I have plenty of overhead so.... Anecdotal.
just upgraded to a Ryzen 7 5800x running it with a RTX 2070 non super and 32gb of DDR4 ram. I have seen a 10-15 frame increase in performance from my Ryzen 7 2700 and much smoother performance overall using vulkan. I'll have to go back to direct X to see if the changes are consistent between the renderers and also check to see if your findings with a possible memory leak are consistent.
when i use vulkan all the screen in the game break and start glitching out.
If you was trying to play this game on Intel Arc A770 16GB it was nearly Impossible to get good frames on dx11 and the micro stutters was insane unplayable and now with Vulkan i can play at 60fps on 4k native Resolution when using Lossless Scalings frame Generation
I've run the game on vulkan and didnt notice anything but a lower average loss of 20 fps. Even DLSS doesnt seem to do anything for frames in my testing. Like Im running a 4090, both of these should gain some form of fps improvement if they worked correctly. lol
sticking with dx11
Yeah I found Vulkan to be super smooth, good frame times and a glassy feel. For some reason makes my OLED screen kick in its auto dimming so everything is really muted. Hopefully sorted out in a future patch as it seemed VERY promising
Could in theory be something to do with the lack of HDR support- hopefully they'll get it working soon.
@@tenpoundfortytwo Yeah assumed as such :)
On AMD the game doesnt launch in Vulkan. You have to manually change it back in the game files to fix it
I have an RX 6600XT and the game runs fine with Vulcan for me
I have tried both Vulcan and Dx11 with a 3090 and 4k Alienware monitor.
3dx supports HDR, Vulcan does not yet (not available)
I have found some artifacting with Vulcan periodically but it does run smoothly.
I don’t see much difference between FPS between the two over a full play session.
I have noted Vulcan does boot into the game much faster than 3dX11
Its interesting, but still needs some work
I use the Razer Blade 14 2023 with a Ryzen 9 6900HX and 3080 Ti, when I use Vulkan the game crash and close. 😢

Just interested why you assume the higher memory usage is a "bug"? It could also be explained by the API keeping more assets loaded into video memory. I would like to see if there's a degradation of the performance after several runs without restart. Perhaps having the otherwise unused VRAM occupied could be a good thing?
Also I've heard reports that Vulkan is crashing on AMD cards which is ironic as the technology was invented by AMD. I have an AMD card so didn't turn it on myself yet after reading these reports.
I personally use Vulkan simply due to the improved smoothness and reduction of stutters due to the shader precaching. Also, the Vram leak isn't really a hindrance on my machine because I'm using a 7900 XTX that has 24 Gigs of Vram and even after 3+ hours of playing the total Vram usage with Vulkan didn't go beyond 15 Gig. So it does seem to use more Vram over time compared to when you start the game but it isn't by much and it doesn't keep on climbing over longer playsessions.
К сожалению не у всех есть 24гб видео памяти, у меня к примеру всего 12гб,а у большинства думаю и того меньше.
Great analysis! Minor critique; can you keep Vulkan in same location in graphs (e.g. top). Difficult to follow with it jumping location.
Thank you for making this very informative video. In 3.23.1 using a 3080Ti and HD how would you make the graphic settings ( upscaling, upscaling techniques, and HDR) ?
i would love to know what difference to expect on an amd gpu. the current beta has been very choppy, although since yesterday i would call it playable
Keep an eye out later today!
@@tenpoundfortytwo love it, you always deliver
Somehow, when I use Vulcan, it turns off my Riva Tuner. Other than that, it is smoother than Driect X11
On my subminimal system I get enough CTDs using Vulkan and upscaling (TSR or FSR) together to make it annoying.
I have had some pretty bad stuttering with vulkan, luckily with dlss set to 66% my 3060ti can push 45fps on orison at 3480 x 1440p and about 35fps with clouds set to high.
man, a 3060ti for a 27" monitor... ur GPU should suffer a lot ;) i have a 3070ti but on a 1080p (24" monitor) and always get 60 to 120 fps, huge difference
on vulkan oafter 2 hours of playing fps drops at 20 and need to restart the client to fix the fps...not good for me yet
Also, when I run the game with Vulkan and try to join the party leader, the game crashes.
when i enable vulkan and try to enter the game, the "enter the universe" button is just not there for me for some reason XD guess im sticking with dx11 lmfao
I think 1% differences are more meaningful when the averages are so close. Exciting to see CIG optimizing performance. Maybe my 4080 will be my last GPU.
having issues where RTSS breaks on vulkan with my AMD gpu
I found that Vulkan did not play nice with upscaling, it seems that might be fixed in 3.23.1, but I will await development further along before trusting it further
I find it a very weird implementation so far (I know it's not multi threaded yet), I'll get 50fps entering a bunker on ceiling, then 20 fps as I walk outside it. Other weird bits, if I have bad fps, then change the dlss mode to anything else, then back again, my fps will be back to reasonable.
Vulcan feels smoother for sure. I feel like the lighting is very different with 1080p highish settings some places are really dark. (11600fk+/3070/32GBDDR4/Evo970SSD) I haven't had any issues from the memory leak yet but maybe that is part of why my friends 40 series card wont run the game on dx12.
Vulkan seems to be better choice for cases when you have marginally enough vram on board. If less - Vulkan cause a massive fps drop after some playing time due to vram leakage. There is IC on that.
So if you target 4k and have 3090 or 4080 and above you should be good to use Vulkan.
Considering that my RAM usage goes up to 36GB now, you might have even better results with more RAM. I'm messuring a 10% increase in FPS with Vulkan (up to 170).
7800X3D, 4070 Super, 48GB RAM, core isolation turned off
How's DLSS doing in the new patch? Did they fix the UI flicker issues from PTR?
Now if only FG would be implemented, so many CPU bound PC would benefit from it...
Although I was actually surprised about DLSS since many people said that this was going to arrive in years if ever.
VRAM usage might just be a different caching behavior. As long as you don't run into stutter when it approaches your maximum, it really doesn't matter how big that number is.
Yep good point!
I played on 16 gigs of ram with vulken and it crashed so much. Swapped over to dx11 and it was so much more smooth. Just changed to 64 gigs of ram and vulken still feels a bit frame droppy compared to dx11 and i did notice memory leak when stress testing on vulken. Dx11 right now seems the way to go
Been using Vulcan ever since the option was available.
I get lows of mid 20's to highs of mid 60 frames @ 11,520 x 2160 using 4090 set with a 90% power consumption limit.
4k 😂 massive L tested 2k vs 4k no difference in fidelity
@stevieC11Hanworth my 3 x 4k screens don't care so much.
I like how it looks, that's all that really matters.
@@VonSpud it is all that matter I just believe 4k is over rated. Happy gaming on that mini cinema set up
@stevieC11Hanworth thanks, the only pain in the butt is I have to do alot of head turning to read stats on the outside screen.
@@VonSpud I can imagine yes
interested to see what kind of performance can be had with a multi gpu system.
Does the CapFrameX / RTSS overlay work for you in Vulkan @tenpoundfrotytwo? Mine just flickers on and off at random intervals.
I actually didn't have it on at all- I'll give it a go and see!
I have exactly the same problem
Thank you for all your testing!
Vulkan has been fine on my 2060 when I tried it but the real winner for me is DLSS Quality . The game feels so much smoother and there's a disinct improvement in visual quality in my eyes compared to native. I can finally turn the clouds on very high and not turn into a slideshow.
Even though it's minor (for now), it's a great step towards optimization nonetheless. Good shits CIG.
I hope Vulkan will be the default API in SC by the end of the year. We're in 2024. It's time to leave ancient DX11 behind for good. Having Vulkan also means we'll soon be getting real time ray tracing.
Could you do a modern video of nvidia control panel settings, what should one have them set at.
i have good perfs(60 to 120 fps) with vulkan on a middle range computer (i713700K with a 3070ti and 32GB of ddr5) and always use the defaut set by application i nvidia panel...any time im tried to set differents things using 3d settings it always cause problems from crashes to less perfs.
Absolutely heroic work by you with this. Cheers.
Thank you! I hope multithreadding will help to get better fps and better frame
Yep hopefully we'll get multithreaded rendering soon!
On my system (Ryzen 5 5600X, RTX 3070, 32 GB RAM, 1440p native resolution, DLSS enabled) I experience poor frame rates in Lorville while using Vulkan. While walking around it's around 20-25 fps and that's making me dizzy. I had much smoother frame rates in the same area in 3.22.
Don't know why I'm experiencing this with Vulkan enabled.
Single threaded for now. That is why. CIG did say because of that the performance at some locations will be poor. Read the patch notes.
Hummm are memory leaks permanent? I had great results using Vulkan, but damage to my GPU would be a reason for me to go back to Dx11.
When I try using vulcan my screen is just black, all I can see is vapour vfx :D
I see significantly less stuttering on my high latency connection here from South Africa using Vulcan.
Tried Vulkan, but no HDR is a hard no currently. On a 4090 my FPS is fine with DX11, and HDR is something I can't play without. When HDR support is added to vulkan I'll likely switch as the better renderer - and probably the renderer they will put the most dev time into in perpetuity.
My 3060 didnt like Vulkan. At all. Switched it over, relogged, loaded all the shaders, opened game and vid card started making pretty loud grumbling noises I have never heard before. Switched back to DX11 and no issues.
Vulkan is way smoother for me, but sometimes just decides to cap my FPS at 40, so DX11 it is until Vulkan gets ironed out.
I've run the game on vulkan and didnt notice anything but a lower average loss of 20 fps. Even DLSS doesnt seem to do anything for frames in my testing. Like Im running a 4090, both of these should gain some form of fps improvement if they worked correctly. lol
sticking with dx11
SC and memory leaks, no stronger duo that that 🤦🏾♂️
i got a rtx2060 and unfortunately vulcan destroys my fps, on dx11 in large cities I get 30-40 fps, with vulcan 15-25 :(
Great perspectives over all systems !!
