alt Hacker NewsThis is overestimating the amount of effort involved to game on Linux, imo. It is true that there are a couple games using kernel-level anticheat which preclude their working on linux, but for the most part the effort required to play games on Linux now is zero if it's a Steam game and almost zero elsewhere.
Rust on Linux only works for Linux based servers https://www.protondb.com/app/252490
Apex Legend used to work but doesn't anymore (still marked Silver) https://www.protondb.com/app/1172470
Delta Force used to work but also doesn't anymore (still marked Bronze), people are tinkering with config files but nothing seems to work https://www.protondb.com/app/2507950
NARAKA: BLADEPOINT is working but requires custom Proton, some tweaked settings, launch options, etc https://www.protondb.com/app/1203220
GTA V public lobbies don't work, requires you to tweak launch options, disable battleeye anticheat, seems to just not work for some people. https://www.protondb.com/app/271590
BG3 also seems to require a custom Proton and tweaked settings for some people https://www.protondb.com/app/271590
It goes on and on these were just from the first few games sorted by player count. Much of the tweaking seems to be different person to person, sometimes it just works sometimes it's Nvidia's fault, sometimes it's something totally different. There's a "recommended for tinkerers" option for reviews. To be clear, every single one of these works right out of the box first time on Windows.
