@rejzor @nixCraft Enable Proton in Steam, most games will run. Especially older ones should run better on Linux. True about anticheat, Spectre Divide, Valorant and some others won't run. Apex Legends, The Finals, Hunt: Showdown should run (Hunt Showdown has problems with it's server pinging implementation but that should be so for all platforms).

A good place to check compatibility is protondb.com

Also look into using github.com/FeralInteractive/ga , should have packages in most repos.
