AMS2 and Pico 4 constant stuttering since the last update from Pico...

So Pico updated their software and now i cant limit the fps to 72 anymore. The option is gone.

This somehow screwed my frame synchronization. Im running AMS2 on a 4090 / 7800x3d combo and all was fine until the update.

The game stutters badly, although my cpu usage is at 30-40% and my gpu usage is at 60-70% (using fpsVR from steam to track everything). I guess it is a vsync / framesync problem. I limited the FPS in ams2 to 72, did the same in the NVIDIA settings and the game is running constantly with 72fps, but it stutters wildly...passing cars stutter, the world stutters...its not fun anymore. VSYNC on or off doesnt chance anything...not in AMS2 and not in the nvidia settings.

LMU doesnt have these issues...it does run at ultra settings with no stuttering. But i dont like it, because it doesnt have a good offline mode, like AMS2 does.

Any ideas?

 

I'm not familiar with the Pico HMD, does it use Steam VR or Open Composite? I've had Steam VR running while my HMD should be using OXR, that (or vise-versa) can cause various issues.

 

Just in case somebody is experiencing the same problem. You can switch between the 72 and 90hz mode now in the settings from the headset itself. It used to be changeable on pico connect online on pc...i dont know why they changed that.
