One big issue with Linux / SteamOS gaming is a lack of anti-cheat support, and it seems Electronic Arts (EA) have future plans for supporting the platform.
Currently, EA’s own Javelin Anticheat does not support Linux platforms at all. As a result games like Battlefield, EA SPORTS FC and various others simply don’t work. That may change in future though, especially with the rise of SteamOS / Steam Deck and the future Steam Machine.
Eww, EA can keep their trash to themselves…I’ve heard about all the problems that Javelin has and don’t want it anywhere near my games. Not that I play EA games these days.
