pretty sure mw19 uses the new anticheat called ricochet which im pretty sure runs kernel level which makes this game unplayable on linux

DDAnaselo 2026-04-05 github

I just checked, black ops Cold War uses server side anticheat, not client side which makes it work with proton, but mw19 as you stated uses a client side kernel driver. I guess support for this game will never come until activation makes ricochet support Linux, or strip it out entirely ?
