DCS World VR Performance Test - GTX 1080 vs RTX 3090
HTML-код
- Опубликовано: 5 окт 2024
- So I upgraded my GPU, and was very curious on the performance impact this would have on DCS World. Went from a 1080 to a 3090, which in many ways, it is a pretty decent upgrade. I have currently own 2 headsets, so I decided to test them both with a before and after. Sadly, my low expectations should have been even lower. Hope you find the results entertaining!
I also made a comparison between the headsets for DCS, if you want more information about these, be sure to check out • DCS VR - RIFT S vs QUE...

I love you all! Thank you for the continuous support!
I have to be a dissenting voice here. I upgraded from a 1070 to a 3080 and from a rift s to a reverb g2.... granted...had to mortgage the house, but I got a substantial improvement in DCS. Frame rates are not the only measure. What astounded me most is that I can play multiplayer with the frames locked at 45 fps...and that's with pretty high settings, and in multiplayer. We did a mission with my squadron on saturday night with 16 people online and I was still getting a consistent 42-45 fps in the caucuses map. We had 16's, 18',s 14's and a10's. The only map where I get really crappy framerates...down to 20-25 fps is sitting on the ground at Incirlek on the syria map. My computer has 32g of corsair memory, i7-8700 and I've optimized the cpu usage and nvidia settings as per the advice on VR4DCS. The real issue though was visibility. Fly formation and being able to see clearly in dogfights was difficult. I was lucky to see anything further than a mile other than being lucky to see a speck. I have measured distances in tacview and I can easily spot aircraft at 3-5 miles and large aircraft like tankers at 10. The other night, I was flying at 20K and looked down to see a pair of 16's headed back to base, and they were at 5K yet i could see their planform over the water easily. So for me, it has really made a world of difference. Yes...DCS sucks when it comes to VR performance and like most of you, I hope they can fix that but I've lost my optimism for that. However, it's not terrible. The upgrade made playing the other VR games so much better. IL2 is superb, and things like halflife Alyx and lone echo are just fantastic. Anyway, my 2 cents worth.
Thanks for the feedback
Thanks for this. You just saved me about 2 grand. I'll stick with my good old gtx1080
I have a few titles that are edging me towards an upgrade, but after seeing this I'm like nah, it's fine, I'll wait till cards come back to normal prices in a year or two. Holy damn that's a lot of money for nearly no difference.
@@bhante1345 ye this might actually give me a reason to actually start vr training my self instead of buying a track ir set, also a 3090 or 3080ti is my lost to get, for the Ray tracing but also for the improvements in heat, as I have to emit I try to milk my gpu for as much performance
DCS really is a dumpster fire when it comes to multi-thread support and optimisation.....but gotta keep pumping out those new terrains and WWII asset packs to sell....sheesh. Every new 'product' for sale is just another middle finger to the customer base that have put up with such shitty optimisation/performance for so long because they have invested so much already, and are just waiting for ED to pull their finger out of their ass and give a crap.
"Vulkan API and Multi-threading
With the integration of these libraries, DCS will benefit from improved performance throughout, including in virtual reality. This has been a substantial task to develop and integrate into our codebase, but we are nearing the end of this journey, and expect it to be available in the 3rd quarter of this year(2021)."
I was waiting for benchmarks on flight sims using reverb g2 and rtx3080 or 6800xt before making the purchase. The results shown here are not encouraging
The results will always be shit until DCS switches to Vulkan api, regardless what brand gpu you use. Its a cpu bound game
@@guybrushthreepwood3002I don't play DCS anymore as I lost faith. I can't find benchmarks for IL-2
@@AMZdogfight You got VTOL VR for vr. It is a great game for VR flight the best IMO.
CPU bound game is still CPU bound...
I was not expecting much for being a CPU Bound game, but I wasn't expecting this lol
@@XCHECK This.. This is pretty bad.
@@XCHECK yeah see... i go on reddit and tell people upgrading your graphics card won't give you more fps, but you can turn settings up higher and get the same fps and get downvoted to hell, but I still don't think im wrong.
The GPU can only work when it's been provided work from the processor. Basically, the processor does all of the 'general' calculations regarding the physics and events that are happening on screen in the frame. Once all of that is finished, it hands off this information to the GPU, which then adds polygons, shaders, and whatnot to create the actual image. Basically, before the processor has handed off all information, the GPU has nothing to provide shaders, textures, and whatever to, in order to create the final image.
Upgrading to a faster GPU basically means that the GPU can finalize the frame faster, but unless the CPU is ready to provide it with another frame, it will then idly wait. It cannot create more frames until the CPU is ready to hand the information the frame is supposed to be based on. Upgrading to a faster GPU, therefore, has little to no impact on the framerate, as you're waiting for the CPU to finish its task. The only time where it makes sense to upgrade the GPU therefore is when you're in an opposite scenario, where the CPU is able to provide frames faster than the GPU can draw them.
So yes, if you're in a heavily CPU bound scenario, you can increase purely GPU bound settings, without any hit at all to the overall framerate. The GPU will take more time drawing out the images, but it won't matter, as long as it's still finished before the CPU is ready with the next frame. As long as the settings you're increasing in DCS do not also increase the load on the CPU. So for example, you might be able to increase anti-aliasing (SSAA) and Texture levels with no performance hit whatsoever, while you might suffer a performance hit from a higher view distance, as your CPU also has to calculate physics for more units.
The same is true for upgrading to more or faster RAM, or an SSD over an HDD. With more/faster RAM or faster storage, the CPU then spends less time waiting to access the assets it needs in order to finish its job, which in turn allows it to hand of more frames per second to the GPU.
@@mackan072 doesnt make sense in this video. seems he has a damn good processor, look at his usage , the cpu laughs at dcs how low he has to work. me while the gpu is at about 70%.
Well, have you disable ASW ? because these fps capped to 45hz are pointless.
With that 1080 you might get 45 and with the 3090 you're probably at least above the 60, but since ASW (and your headset configured to 90hz), it gets capped down to 45 fps.
Try disabling it and bench again.
wow, it looks so stunning, and whats funny is i fly in the a-10 II in vr at pretty low settings and it doesn't even look bad, so imagine having high settings like this :0
DLSS would be a great improvement. As I understand it, DLSS can still be used even if there is no ray tracing. the developer just has to implement it. I use a Pi Artisan at 120Hz and it looks great. I can't complain about the performance with a 3700X/2080 Super but I would love to maintain 120fps. That would be SWEEEET
DLSS and Raytracing are completely different techniques that have nothing to do with each other. But yes, DLSS 2.0 could be great. However, you will never reach 120 fps even with that, because the big problem is much more the cpu bottle neck. Even if the performance was recently improved, it is still far away from your desired performance. Soon the vulcan api is supposed to come. That could be a leap forward again.
Hi-res headsets and today's GPUs are all about compromise. The RTX 3090 is only a little more than 2x faster than the RTX 2060 Super. We'd probably need a card about 1.5-2x faster than the RTX 3090 to really get to a good place for hi-res VR headsets.
Many thanks. Good comparison, for me at least (i7 6700K @ 4.4Mhz, 32Mb RAM, 1080 8Mb). This isn't good news. And I was _almost_ ready to pull the trigger on a new system for DCS. Glad I didn't. Granted I do turn things down/off for VR but, man, I'm seeing numbers closer to your 3090 than your 1080.
I saw a healthy jump in X-Plane with Vulkan in VR (made it useable). Not saying the engines are the same but, still, a boy can hope. But only for so long...
Thanks for posting this... My 1080 is still great on my 2560x1080 widescreen, but I was hoping to get a 3080 to crank up the settings in Quest 2. I hope when the Vulkan updates come the game will take better advantage of my 8 core 9700k... maybe i will actually be able to get a 3080 when the Vulkan update comes out in 2022 :)
2023… hopefully
Running the same set up 3090 and a 3900 with a reverb g2 everything maxed for the most part and using the DCS SS of 2.5, I’d say this is a little low. Super carrier in the tomcat or f18 is usually 38 and caps at 45 when you look away from the bridge
get a intel chip or new amd 5000 chip
I think this video would be much more informative, if the scenes would not have been recorded with a plane standing static on the ground/carrier, and moving only your head around, but rather making high speed low fly-bys over densly populated area with overwhelming amount of details, showing the momentary FPS rather that a max min value (hope I didn't miss something). How could a stronger card show its advantage over a weaker card by showing almost still pictures? Just my 2 cent...
Agreed. My 3090 gave me a huge boost in frame rate over my 1080. Great purchase.
Hi XCheck, thank you very much for your very interesting videos. I have nearly the exact same setup. I was wondering if the Rift S is still worth it for playing DCS, or I'd better wait for the Reverb G2 which seems to be out of stock for ever, just like the RTX 30 cards...!
I am waiting for this since your last video.
Thanks for compare! Im sure Eagle Dynamics work for an optimization. Like in IL-2 Great Battles, the performance increase this year was amazing. Whats about the super highend 3090? You stay with her or you return?
Guau ese equipo te tiene que haber costado un ojo de cara, la verdad es que estaba pensando en comprarme un pepinazo para jugar a DCS pero veo que no merece la pena hasta que DCS no optimice el simulador, es preocupante ver cómo no paran de sacar módulos en vez de optimizar qué es lo que deberían de hacer, estos se creen que somos tontos y qué nos vamos a conformar con la mierda de optimizacion que tienen, lastima de la gente que se gasta un dineral pensando en que van a poder jugar mucho mejor y luego se llevan la decepcion
3090 was a huge improvement over my 1080. No audio on the video made it useless unfortunately viewing on a phone.
Bad optimisation coupled with last gen CPU bottleneck = terrible performance
I get a stable 20 fps on the lowest settings with my 1070 and quest 2 lmao. And then seeing that a 3090 gets 45 fps at the VR preset is just sad.
Why do u guys even play vr at 20fps? Its so bad
@@evengreven5515 well I don't have track ir so I just use VR and over time you get used to the 20 fps but I got a 3060ti and that should make my experience a bit better.
@@apebble9740 ah my man got his 3060 ti. I had the option to order it but i hesitated and decided to go for the 3070, congrats tho its a beast of a card
@@evengreven5515 Thanks dude I wish you luck on getting that 3070!
@@apebble9740 thanks, have a good day :)
very strange. I just upgrade my GPU from a Gigabyte 2070 Super to an AMD 6900xt and saw 30-40 fps jump in this game. I have the same cpu. waiting on my AMD 5900x to show up though.
looking to do similar. would you say it is worth it and could you increase the Particles much in VR settings?
@@Ravasempai yes. It made a huge difference.. I’m now waiting for them to make DCS multithread compatible. That will also help.
TLDR: The 3090 is always gonna be faster than 1080, im wondering more about gtx 1080 vs rtx 2080
What about Quest 1?
Im playing it on r9 390 and it is great
But you are not playing using a VR headset
I will go for one Amds new Generation Cards, bc Im more the AMD fan and its cheap :D
Them are looking goooood!
CHEAP?... Where did you get that?... Check actual prices of cards, not fantasy MSRP posted by AMD...
There's no point in being a 'fan', as neither of the brands actually care about the end consumer. All that matters is that you purchase their stuff so that they can earn more money, that's their only incentive to care about the customer.
I do however wish that AMD gets a 'win' this time around, and am very happy that people are excited about AMD's products. We really do need competitiveness within the GPU space, and AMD has been sagging behind for too long. Ther recent development really is amazing for us consumers :)
@@pawelkrupowicz2539 Nah I mean its cheaper than Nvidias ;D
@@happygamer4932 the problem is that are not... Actual RX 6800 XT cards are more expensive than comparable RTX 3080 cards, even though they were supposed to be cheaper...
Song name?
I wish I could make some sense of your video. I can't work out if you're getting any real increase or not. I'm running a 10900k all core OC at 5.1GHz with an overclocked 2080ti all on Watercooling. I have a Strix 3090 OC on order but trying to work out if it will give any benefit with the Reverb G2 I just received or an LG 48CX. DCS World and FS2020.
I know they both use DX11 and so only use 4 cores 🙁. Both are supposed to go to DX12 or Vulcan within a year.
Any comments that might help?
More stable locked framerates, but really no real increase on framerates sadly. 3090 for DCS or MFS currently is a waste of money sadly, unless there is a unreal leap in single core performance in the next cpus, or they implement DX12 or vulcan flawlessly in the simulators, top tier gpus will not be fully utilized. That being said, with your cpu you should get better framerates, but I would be surprised if you fully utilize a 3070.
DCS is supposed to be Vulcan ready within a year.. That's very optimistic :)
Better GPU in DCS just means you can have better image quiality, not higher frames. So run a higher pixel density and subsequent sharper graphics in VR. You see when he bumps up to 1.5SS the GPU is used more, but FPS stays the same. Is just how DCS works, so yes the 3090 will give you the option to increase just image quality settings - not stuff like more trees or better view distance that uses more CPU.
DCS use the same graphic engine from the old LOMAC of 2003
That´s why is so crappy
LOMAC uses Flanker 2.0 engine.
Code evolves, it is still C++
MSFS uses partially old code from FS. Windows 10 uses old Windows code. Nobody recode from scratch, except dreaming managers.
True. DCS needs to slow down with the modules and work some optimized multi thread code into the game.
First lol
Using an AMD cpu on a "high performance" PC. LOL'ed
Using AMD on a gaming PC lol.
