R6 Siege, Apex Legends, PUBG, Insurgency Sandstorm (which seems to be an off/on thing from the descriptions.)

Thanks for posting this, I didn’t realise how many of my most played games have issues, or are unplayable, according to Proton DB. I forgot that it was effectively impossible to play a huge number of multiplayer games with anticheat/whatever stuff.

Again though, appreciate it!
