The reports are already coming in of the game failing to launch on Proton. This won’t ever be fixed because its a KERNEL ring 0 level anti-cheat, and Proton prefers userspace DRM like standard Denuvo Anti-Tamper. https://github.com/ValveSoftware/Proton/issues/3773#issuecomment-628907497
VFIO reports aren’t in yet, but since this is also a ring 0 anti cheat exactly like Valorant, this doesn’t bode well. Proton and Wine were basically half a step forward, 1 million steps back. It’s also a HUGE security risk.
Need reports of this with VFIO people as soon as you’re able to sacrifice a machine. Remember, it’s ring 0, so sandbox that stuff (even physically) like crazy. Valorant though doesn’t work in a VM so I don’t have good hopes for this.
In the meantime, if you’re angry, tweet about it using #FCKDRM and maybe GoG will listen.
