Yeah, so like everyone else has said, generally yes. There are occasionally issues, but the only issues I’ve had so far (that see actually issues with the game running and not anti-cheat that just blocks Linux) have been solved by fixes I found on ProtonDB.
Apparently, on average, games actually run even better on Linux. This is due to the combination of a less bloated OS, but also because proton is translating DirectX into Vulkan, and doing it a smart way such that it’s actually more efficient usually. So far, it’s only GamePass and those few multiplayer games that have fallen short.
