I’ve run into many, the latest being Rising Storm 2. Its development has been suspended and the EAC is a version that doesn’t work with Linux, so you can’t play on any servers except the ones that allow hackers. There’s also the issues with performance in Squad on Linux. Starship Troopers: Extermination also runs better on Windows. That’s just the ones I’ve had an issue with in the past month.
That being said, I’m still not willing to go back to Windows, even to play these games.
