Proton Anti-Cheat runtimes?

[theinsanegamer23]

On Linux, games with Easy-Anti-Cheat and BattlEye Anti-Cheat can optionally support running on Linux via the Proton runtimes for each of these provided by Steam. Games that use these to my knowledge include Elden Ring and Nightreign, Halo:MCC and more.

Is there any possibility these could be supported?

Do the Linux/Proton enabled versions of the anti cheat engines require root privileges or kernel models?

[Milo721]

Correct me if i'm wrong but as far as i know they run in userland without the need of kernel modules or root privilages the binaries are the Linux native ones that the anticheat accepts as valid for the Windows version and a Proton env variable sets the path to the anticheat runtime downloaded from steam eg. PROTON_EAC_RUNTIME=Path or PROTON_BATTLEYE_RUNTIME=Path.

It's a matter of having the runtimes in a path common to all the prefixes, like Heroic or Lutris do with the Steam path
