All my games work, however I avoid games that require kernel level root kits to run so your mileage may vary.
If you ever have an issue with a game running under proton. Look up the game in ProtonDB and make sure to use the filter to match your hardware.
I get avoiding those games on principal... but is there any harm that can come from playing those through Linux?
Its a kernel level rootkit, so if you have that installed your computer is no longer yours. They could in theory, read your RAM and use it to read encryption keys and have full access to your system and you would never know.
A kernel level rootkit for windows though. What is it going to have access to in Linux? Isn't it just reading Proton's windows files that are created for each game ran through it?
They won't run on proton. "Kernel-level" means it's well below the level that Proton runs at.
Helldivers 2 runs fine through Proton with it's anti-cheat. It was claimed to be kernel level.
My understanding is that actual kernel-level software would have to at least have a Linux-specific driver included. Otherwise if it really is running entirely through Proton, it's somehow faking the ring 0 access. I'm not entirely sure, but I do think that anti-cheat must work differently from the big ones like FACEIT and Valorant.
You may be right, but I don't know enough about proton to say it's a well isolated sandboxed environment. I'd rather not have it on my PC at all.
