Game servers are fairly frequently hosted on Windows, simply because the game server often shares a lot of code with the client (including libraries which may not be cross platform), and game developers are often most familiar with Windows.
VR on Linux depends on your headset mostly AFAIK. Oculus (Quest will work with ALVR streaming, but I had mixed results) and WMR require software that isn't on Linux. Valve Index supposedly has good support and VR games are playable with Proton.
i don't know anymore. i'm getting really annoyed by background processes interfering with my counter-strike ping. like microsoft is checking my mail or uploading some telemetry bs or something. i can't wait to get back on linux.
it's interesting that you say that. i recently installed Portmaster for another reason and have been turning it off when playing CS as it was blocking it. I will look into configuring it. Cheers.
this loaded question should be directed towards the developers.
that any Windows game works on Linux at all, given Microsoft's record regarding interoperability, seems like a miracle.
If I had to make an equally loaded question I'd say, what OS are they using to host their game servers?
