“MSI Afterburner is to blame,” but this issue also occurs with Precision X and HWINFO64. These problems have persisted since the release of the 3000 series and have never been resolved. Most of us who have encountered this issue simply shut down any monitoring tools before starting a VR gaming session. This problem has been around for so long that I’ve stopped looking for a solution and just accepted that it’s easier to close these apps and move on. Thank you for addressing this issue. Hopefully, it will gain some traction and eventually get fixed. Ideally, we shouldn’t have to choose between monitoring our hardware and having a smooth VR experience.
@@bmwM3M5M6 I do not use them anymore so I can not give you an update on those, but you know ymmv... try and see if there is a better experience otherwise go back using them, GFE I do not expect to generate any issues tbh, RTSS not sure though.
Well, read the manual, read the forum. If you add sensors for no reason and especially those who have a high polling time sure it is having an impact. It's not the software itself, but how you configure it. In the Monitoring Panel of MSI Afterburner you can right click and enable the profiler panel which will show you exactly which sensor takes how much time to poll. Especially external sensors like those by perfcounter.dll have a huge impact. Use only those which you do need, preferably the internal ones and untick every other sensor. FPS, Frametime, GPU temp, GPU load, CPU temp and CPU load are not heavy and won't give you a noticeable impact while gaming.
@@BenchmarkOdysseys just an addendum, when you are not using MSI AB for monitoring but RTSS overlay. When you are in the OverlayEditor and opened the "Add new data sources" dialog, hold CTRL and instead of the value of the sensor you get the polling time of each sensor value. So even there you can already inspect if the sensor you are about to add will have a significant impact.
i think the problem is that these are polled as per default. which is not optimal. rather have users who REALLY need power sensors in their overlays read the manual and configure it to add these. than having ALL users have the performance heavy situation right from default installation.
@@zorrothebug Hey, do you know if only checking the box for "GPU power percent" causes the stuttering, or also just looking at the sensor value in the RTSS OverlayEditor under "Add new data sources"? If the value is being displayed in the OSD with help of RTSS and MSI AB, it stutters (especially in the original black ops 1 from 2010). But if simply monitoring the value causes high ms and stutter, then looking at it in RTSS should cause stutters or not? Even if I remove the value from the OSD In MSI AB, I still get stutter as long as the Box for monitoring is checked for "GPU Power percent" under Settings → Monitoring, or the checkbox "enable unified gpu usage monitoring" is checked under General Settings. So what exactly causes the stutter, the monitoring or displaying of the sensor value, and how can I be sure that I fixed it?
@@dstendo64 it is the polling of the sensor data which causes the stutter due to the time it takes to get the data from the driver. It's a driver thing, not MSI AB nor RTSS. Displaying that data on screen is negligible time, not even a single ms. So when you are monitoring that sensor, it gets polled and causes the stutter you witness.
brilliant advice. these apps do some work in background, I agree. Will test to turn it off .7900xtx and ryzen 7 7800x3D CPU. VR is Pimax Crystal Light.
precicely because of similar problems like this i have for years now, during normal gaming sessions, completely shut down all 3rd party tools & programs that i can. i do not need an overlay during gameplay at all!. the only time i use rtss / afterburner is for initial testing of settings of new games to find my preferred performance corridor to enjoy the gameplay. with a nice balance between fps and visual quality.
I'm a firm believer in there are too many polling type events that are happening. IRQ events, so to speak. Too many of these interruption events are preventing computers from working as expected and to their potential.
Since this video I've fallen into a bit of rabbit hole researching. This type of trouble shooting is a lot to ask of a 'normal' sim racer. However, we use a lot of USB devices, plus 3rd party software of varying sophistication and quality, and iRacing is always going to slam a couple CPU cores. Then there's the user requirement for smooth, perpetual forward motion across 3 screens or VR... and it's a recipe for a stutter stew! I would need to find a way to clearly capture the stuttering, especially if the 'on screen' image is the only real evidence. The only thing I can think of is a high speed camera like rtings use to collect motion tests on monitors. It's not a small undertaking. And I worry that the results won't be interesting or consumable.
Can confirm I had this same issue with stutters with other Sims (Assetto Corsa and IL2 Sturmovik) when I had used Afterburner in the past. Stopped using it and they went away.
Some sensors (like power or voltage) can have quite high latencies. The GPU driver can stall (it's the driver that actually does the polling when Afterburner or HWinfo or whatever requests it.) You can enable the sensor overhead calculator in Afterburner to see which sensor group is problematic and disable those. Although as always, it doesn't make sense to keep playing with monitoring software running. Use them only initially to find the performance sweetspot for your system, and after that's done, keep them closed.
@RealNC Cheers mate! I will confirm the latency issues. Great reminder about closing unnecessary apps, especially when you've signed into a race and can't do anything about it until the finish line. [Edit] Yup, definitely "GPU power percent" at a constant 14ms and spike even higher.
Have been seeing similar symptoms and will try this tonight. I have heaps of monitoring (including logging iracing telemetry to influxDB) and have been chasing this issue for ages (13900k/4090/1440p triples)
Good work, funnily enough I was having a audio popping issues every 4 or 5 secs. traced it back to afterburner as well. Uninstalled it and instatly problem solved. Haven't really driven in sim since but definitely, I'm going to check to see if removing afterburner has helped there as well
MSI Afterburner has been causing stuttering for years, I surprised it took you this long to figure out, no offense. I used to be an avid user of MSI Afterburner, but after so many issues of it causing crashes in specific games, I started defaulting to have MSI Afterburner closed, and performance across all my games was way more stable.
Interesting, do you know if having the amd adrenaline software opened in the background does the same? Since it's the main tool for overclocking/undervolting etc for amd gpus... I know that there is a way to make it stop registering/recording your pc stats in the background (it's sadly on by default, even when the amd perfomance overlay is off), but not sure if it's similar to the afterburner if you want to just oc your gpu with the performance penalty
I have not noticed the same micro-stuttering from Radeon. In fact, I actually think the image presented by AMD is more smooth than Nvidia (with or without SMP). I haven't discovered an empirical way to show that, besides my own eyes B)
Thanks for this video, i get 5 second screen freeze (but iracing continue with the sound). First time i disabled the nvidia surrond and after no isue... But, i install racelab, msi afterburn and update my nvidia drivers and get the same issue. I close racelab and for the moment, no issue 😅
Yeah I wont use afterburner lol but i will say sim racing games all have some slight stuttering at times. It just happens. Maybe in iracing this is because of afterburner but many games just do it randomly. Its very fast moving motion rven at high fps you cant expect 0 stuttering at all times. Im very sensitive to micro stutters even when people cant see it i do. Ive yet to find a single game, a single year or a single gpu or build that doesnt stutter while im gaming at least a few times lol.
I have only GPU temp monitoring checked and polling is 2000ms also you can entirely pause monitoring if you right click on the graphs, on my MSI skin I can click DETACH and show graphs and you can pause it forever this way
I get stuttering 24/7 at night Spa dry races even when FPS is 130, it’s really annoying and takes away the fun. When everything is butter smooth I forget that it’s a game but when stutters happen I say: Damn it’s obvious just a game. I’m not an expert regarding these things to find the cause but have Geforce experience running but it ran previous season also without any problem so don’t think that’s the issue. I think 99% it’s an iRacing problem with those latest updates you mentioned in the beginning of the vid…
Can also confirm this issue. Happens/happend in DR 2.0 with a 3080 Ti and a Pico Neo Link. Must have something to do with Nvidia drivers. Had been using it for years without any issues. Tried many old drivers but unfortunatly without luck. Also disabled all monitoring. Had to uninstall Afterburner.
In my case stutters were caused by running Virtual Desktop with max bitrate. I have installed VD months ago and have forgot there is still a known issue that is mentioned in Virtual Desktop Discord announcements that relates to Quest 3 and NVidia. Running at lower recommended bitrates has solved my stutter issue. In my case these stutters, when they appeared, were exactly 20 seconds apart.
@@BenchmarkOdysseys I use AV1 codec and in VD maximum for AV1 and HEVC is 200 Mbits. My router can handle this no problem. But there is a known issue: "AV1/HEVC encoding with Nvidia GPUs will sometimes cause high decoding/networking/encoding times at at high bitrates". They recommend lowering HEVC 10bit bitrate to 150 and AV1 to around 120. I followed this recommendation and these 20 second apart stutters disappeared.
@@opminded Gotcha. I haven't experimented with VD yet, I'm a bit intimidated by its customization. But the wired connection I've been using with my Quest 3 is becoming finicky (random alerts of debris in the port), and I don't trust it for long stints like this upcoming 24 Spa race. Maybe it's time I jump into the VD pool.
@@BenchmarkOdysseys If you have it plugged in with the stock charger you will need to upgrade to a 30w+ charger. Like Ugreen. I tried that solution with my Oneplus charger and also ugreen's and it immediately stopped being an issue.
Interesting... I struggled with stutters on a Gsync 120Hz TV but fixed them (I think) by switching GSync off for iRacing, setting the TV to 60Hz and turning VSync on in iRacing and locking to 59fps in RTSS. I don't see why we should have to stop using Afterburner (for underclocking and custom fan curve in my case) just to use iRacing smoothly. The stutters I see happen mostly on newer tracks like Circuito de Navarra, so I'm not sure if it's also down to optimisation perhaps on iRacing's end.
Interesting, I do not have experience with Gysnc TV. What I noticed with Afterburner, however, is that a lot of parameters were selected for monitoring (even with at default) and a few have latency spikes for the 4080S and 3080Ti I tested. If you don't notice a difference in stutters when Afterburner opened or closed, then you do not need to investigate further.
I’ll try it without afterburner and compare. Do you know if disabling the voltage and power monitoring stuff off affects undervolting? I used it to undervolt my Gigabyte Gaming OC RTX 4080 which only really helped with power consumption and keeping noise lower as the card rarely went above 65C on its default settings anyway with the default fan curve. I don’t think it’s critical so if I get better performance without it, I’ll use it without.
It should not affect your undervolt. You can also apply your settings with Afterburner and simply exit the app, and your GPU will still behave as you configured.
Learn how to use MSI AB's performance profiler panel. It is not Afterburner, it is PEBCAK user to blame. Experienced users know how to troubleshoot issues like that and MSI AB contains the most detailed diagnostic tools for that.
@@BenchmarkOdysseys if I had a nickel each time MSI AB & RTSS is blamed due to wrong reasons and I have to comment it, I'd be richer than Rockefeller. :D
I tried doing something similar with VR and reprojection, however, there's some fancy tech and predictive imagery going on with the phone. I had more accurate results with recording at max native framerate (60 on my phone) and slowing it down in the video editor software. It's not as smooth but at least it's more authentic to the experience you see on the screens.
What about Geforce experience ? And Rivatuner statistics server ? The first I use for max fan control rather then auto fan when it’s hot weather and 2nd use for capping my FPS…
I do not install GeForce Experience on my benching systems, I just use the standalone driver. Other ways to cap the FPS include within the Nvidia Control Panel (Manage 3D Settings -> Program Settings -> Find and select 'iracingsim64dx11.exe' then scroll to Max Frame Rate), or within iRacing itself.
