Even gamers nexus’ Steve today said that they’re about to start doing Linux games performance testing soon. It’s happening, y’all, the year of the Linux desktop is upon us. ᕕ(ᐛ)ᕗ
Edit: just wanted to clarify that Steve from GN didn’t precisely say they’re starting to test soon, he said they will start WHEN the steam OS releases and is adopted. Sorry about that.
The only bastion left is anticheat. Everything else are just (bad) old habits fueled by marketing.
…and VR. VR is already finicky on its own, gaming on Linux can be finicky in different ways, and the issues multiply if you have two things like that.
Tends to depend on the headset you own, some work perfectly. Also, Valve is very likely releasing a headset based on SteamOS, which should help.
I work in VR, I play in VR, including Windows games, all on Linux. No specific problem for me on that front.
