I’m using the Pimax Crystal Super and it took me a while to diagnose a problem I’m seeing:
In the Pimax home, everything is fine, but when I launch SteamVR (or SteamVR programs), the following happens:
Starting off, everything is smooth looking around, but if I press a button on the controller to bring up either the Pimax menu or the SteamVR menu, then close it, I get noticeable stutter when turning my head. The game motion and framerate stays consistent, but it’s the rotation of the headset itself where I see stutter that doesn’t go away until I quit everything and relaunch the game
At first I thought it was a lack of performance on my end (Geforce 3090, Ryzen 9800X3D), but I dropped the resolution down to very low levels and the problem still occurs.
Enabling Steam’s motion smoothing didn’t help. Turning Steam’s motion smoothing off, but turning Pimax’s on helped a little bit, but it’s still compensating for a problem that isn’t there until bringing up a menu then closing it.
This might be a bug with Pimax’s software itself or maybe there’s some setting I’m unaware of. Any advice would be appreciated.
Could you please reach out to our tech team to request an internal DLL file for this issue? They may have a file that can help resolve it.
Based on your CPU, it should be capable of handling SLAM tracking — you may just need to lower the image quality settings.
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 it’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 Nvidia’s control panel. It helps too.
There is indeed a tracking update in Pimax Play v1.43.1, but I’m not sure if it will help resolve the OP’s stuttering issue.
Yeah, of course the things I said might not help the OP, but he’s asking for any advice, and I happened to have the same issue like his.
To be honest, the stuttering issue is still there. From time to time I can still see a little lag here and there, but at least it will not keep showing and last the whole SteamVR session like before.

Our engineers are still working on improving the tracking algorithm, and at the same time optimizing CPU resource usage.
