I have just received my Pimax Super UW and got into my MSFS 2024 and started seeing jitters and Lag when I move my had despite that my FPS is high. These jitters are almost like double vision and has nothing to do with my hardware because no matter what resolution and settings I make I still get the same result. Some people say it might be due to tracking issue. I have a special infrared light just for this purpose on a well lit room . I have changed the Light frequency 60 to 50 or 50 to 60 with no result. I have 5090 ,Intel 13900K 64gb DDR5 Ram. So it is not a hardware issue I can assure you on my end. Anybody faced issues like this before with Pimax Super recently šŸ˜• It is not a tracking issue . It is smooth when I match the refresh rate but not even if I am 5 fps lower than my refresh rate let alone half the refresh rate. ---

Have you reached out to our tech support about this issue? It may be caused by unstable tracking, and they can provide an internal DLL file for you to test whether it resolves the problem. ---

I had the same issue, but my hardware is much less powerful. > [@Crystal Super stuttering in SteamVR after menu is open / closed](https://forum.openmr.com/t/crystal-super-stuttering-in-steamvr-after-menu-is-open-closed/42503/3): > > I had the same problem ever since the first day I got my Super. My video card happens to be 3090 too. For a couple months I had to put stickers to block 3 tracking cameras, leaving only one working, and it fixed the problem for me. I just need basic tracking without the controllers so it was fine with me. Then the new update ( I believe itā€™s 14.3.1) update the firmware in the Super and finally fixed this stutter problem. Stickers were removed and the tracking is working fine. By the way, maybe you should turn off the vertical sync in Nvidiaā€™s control panel. It helps too. ---

Try cleaning all 4 cameras with a soft cloth. The cameras are tiny, so any fingerprints on them results with blurred vision. You can check how the camera sees around by enabling the passthrough camera. There must be enough contrast and sharpness in the image. The infrared lights you put might be so strong for the camera. If cleaning the cameras doesnā€™t help, try turning off the infrared lights. I had a similar jitter issue after updating Pimax Play to 14.3.3, but i think it was related with the cameras being dirty, because it resolved after cleaning. Lastly, check your computer for background processes which may temporarily use up your CPU resources which also might result in tracking issues. ---

When this happens with your tracking what are your CPU/GPU percentages at? Do you have the pimax tool up when this happens? Have you tried it without the infrared light? Is there anything moving in your play area? Try turning the monitor off in front of you. ---

It is not a tracking issue because as soon as my FPS reaches to refresh rate exactly that hitching is gone. Also halving the fps makes ghosting . I am not using any reprojection or smoothing just like the youtube creators. Thinking that it was my 13900k I have changed MOBO and my CPU to 9950x3d MSI Mag x870E Tomahawk Wifi and still have the same issueā€¦ When I am under 72 like 50 -60 fps I get these jitters as if I am running 20 fps . ---

I have almost exactly the same hardware as you but better motherboard thinking that 13900k was the problem. I have spent 1000$ more to solve the issue and it is still there. When my FPS matches my refresh rate exactly the issue goes away if I am just below my refresh rate around 50 to 60 FPS I get this problem also if Iā€™m halving my FPS Iā€™m getting ghosting effect when I move my head around or if I turn the plane all the scenery looks ghosted. Also I want to add that my dynamic fov could not go over 25% if I set it to 30 to 50% my performance drops like crazy I go into 30 to 40 FPS territory. Can you tell me what does msfs 2024 reporting as the rendered resolution if you disable eye tracking because mine reports 6,200X5,800 despite that I set my resolution to 0.9 on the Pimax appā€¦ Iā€™m trying to find if this is the main culprit. I get like 20fps if I do not use DFRā€¦ I ussed Process Lasso to make MSFS use only the first 15 cores made sure nothing else uses those coresā€¦ ---

It is not tracking . When the fps matches my refresh rate exactly the issue is gone. It starts happening with 50-60 fps . And halving without smoothing or reprojection causes ghosting effect ---

Ohhh. Uncheck smooth motion and half rate in the Pimax settings. If that IS uncheck (both of them) then that is normal for VR as you cannot drop too far below panel rate before it will hitch. But the ā€œreprojectionā€ and weirdness is half rate, its dropping your frame rate to 45 whenever its goes under 68 or soā€¦ Always keep in mind, you should always be getting the framerate of the hz of your panel or it will possibly not be smooth. This is not like flat screen where you can have varying FPS and still be ā€œsmoothā€ ---

As other users suggested, I forgot to mention that you have to turn off the displays in front of you, especially if they are mirroring the headsetā€™s display, which inevitably confuses the inside out tracking which relies on fixed cue points. This also results with jitters as you described. ---

I really do not understand how does all the other youtubers get buttery smooth playback with 35-50 fps . They are not using reprojection and smoothing I saw their settings and when I asked them if it was actually smooth and if they were seeing any jittering or ghosting they said no. And when asked to GPT or Gemini whatever they say you can have a silky smooth play experience as long as you have steady frame times , this is where I lack. The times are all over the place for me šŸ˜’ Both Hwinfo and the debug fps shows my latency dancing around for some reason even if I lower every setting possible make the resolution to 50% and lock the frame rate to half , it never stays exactly half ,always dancing 2-4 fps downwardsā€¦ When I move my head I see ghosting because of thatā€¦ ---

I highly suggest the use of Process lasso and Parkcontrol. I have moved every process to the non x3d cache and only the game runs on the x3d. Park control makes sure that everything is unlocked and not set to any form of ā€œpark/freq limitedā€ Also you can make sure that the game is locked to the x3d side. All my Pimax software run on the non x3d side. This is why I never have tracking issues even if the game is super intensive. ---

I have already done that using Process Lasso thanks to Gemini suggesting me šŸ˜’ As a last resort I will try different ram speeds because apparently DDR5 6400 might be causing latency. Somebody said lowering it to 6000 helped themā€¦ All the pimax apps and servers are running on 16-31 and MSFS on 0-15 ---

It is not a tracking issue brother like I said already couple of times it is smooth when I match the FPS to the Refresh rateā€¦ And I have already assigned my game to the ^d cores but did not help with hitching when it is below the refresh rateā€¦
