I found this to be working without any issues for me:
Played more than 6 hours over the last 4 days, without any hickups, glitches nor stutters.

Since update form 29th November, the game doesn't start anymore (apparently only on nVidia), it locks up after the Cloudhead splash screen and has to be ended manually.

Starting the game
Worked well for me until the recent october update, now it doesn’t anymore.
It appears on the primary monitor (not headset) when used with proton experimental or GE, and crashes on start on older proton versions.
/edit: it started working again for me
I can confirm that this game is still not working (crashes on the splash screen) with Proton Experimental as of today on an RTX 3070
Works for me with experimental-9.0-20240503b (RTX 2080 mobile, nVidia 550.78)
Can confirm as well - the "normal" version works with regular proton experimental (no downgrading of the game version required anymore)
What SteamVR version are you guys using?
I'm using SteamVR beta 2.6.1
Proton Experimental ("version" file in the directory says experimental-9.0-20240509 )

Compatibility Report
System Information
I confirm:
Symptoms
Both left and right eyes render on the left eye viewport.
Reproduction
Boot the game.
Workaround
This can be fixed by using winecfg to reconfigure the Proton bottle to Windows 10. People report that the same bug exists on Windows 7, so this is not a bug in wine but still requires a compatibility profile to fix as Proton currently defaults to Win7.
