As long as you’re cool being a bit more restricted in multiplayer games (a lot work great! But some developers are blocking linux), and you’re okay with AMD (nvidia is improving though), gaming is basically on par with Windows at this point.

In some cases it’s even better. I have a few games that require weird tricks to get it to work under Windows, but work fine in proton. Even Elden Ring at launch ran better on linux because it didn’t have the micro-stutter issue.
