This is so funny because rust has one of the worst cheating situations and majority of their players are windows users, and theres lots of games that have anticheat that allows linux and have notably less significant cheating problems like marvel rivals. in reality rust doesn't take cheating very seriously because if they did they would have more server side software that detects illegitimate behaviour like tons of other games do successfully...... even most popular Minecraft servers have better functioning anti cheat that is completely server side than rust has while getting kernel access to your pc. its pathetic and lazy development tbh and this entire post from them reads like such extreme cope....
I think Helldivers 2 uses EAC and it works on Proton just fine.
Helldivers uses nProtect not EAC but yes, EAC in general is compatible with Proton. The Finals use to run EAC for the longest and Arc Raiders currently uses it and both those games run well.
Does Deep Rock Galactic or maybe Marvel Rivals use EAC? I could've sworn I've seen pop-ups mention it and those are the three games I've played on Linux. But also, memories are bad, constructed memories happen, yadda yadda.
I thought Deep Rock Galactic was PvE anyway
It is. That's just the only game I've played lately that may have had an anti cheat splash.
Neither of those use EAC. I think Rivals uses some NetEase anti cheat and DRG doesn't use anti cheat at all. Lots of games nowadays have pop ups so I don't blame you for misremembering.
