I don’t quite understand the criticism. It’s not gonna be top of the line, but it’s more than enough to replace my dying laptop from 2015 that I pretty much only ever use like a desktop anyway. And I can save myself the time and effort of picking parts, building, and dealing with shit not working as expected.
No, EAC, BattilEye, and a handful of other anticheat solutions have a native user space linux binary, and wine provides a way for the windows portion to hook into the linux portion, allowing the anticheat host to work with wine/proton games.
This involves the developer enabling the option to allow this when building their game which most devs do except for the notorious few that refuse to enable it because they don’t want to spend the extra .00002% worth of budget into making proper anticheat solutions and instead rely on kernel rootkits to solve that problem for them.
