Quite curious, I'm a VR gamer (and developer) and so far I've just had no problem with Proton and SteamVR, including for officially non supported games.
I am too far into nvidia windows things. I run really extreme games with 4090 and tons of mods. Unreal, unity, blender all that stuff. If there is one thing that windows does okay it’s my use case.
I guess they have me right where they want 😂
Also I am not sure if virtual desktop works on Linux
