[PERF] Jittering on Arch #738
Comments
For me 2.7.4 is complete chaos, just look at this wall of pink I got: For 2.8.4-beta for me its random depending on what mood SteamVR is in when you start it, all I did between these two screenshots is restart SteamVR: Of course the photon latency is still all over the place, so SteamVR is still unusable for me even when it decides to give green. |
I am on Arch (6.9.7), and have Nvidia driver 555.58. I am using Plasma on Wayland. I'm running on an Asus G14 (2023 - GA402) with RTX 4060 Laptop GPU. I have SteamVR beta 2.8.4. I am using a Valve Index. For me, adding My

To Reproduce
Steps to reproduce the behavior:
Expected behavior
Smooth VR experience as is on Windows.
System Information (please complete the following information):
Performance Data (optional, but very helpful):
Screenshots
Additional context

I am using Gnome 47 with Wayland as it just added DRM support (Prior versions of Gnome did not support DRM on Wayland)
I experience the same problem under X11 too.
