Bought days gone (game) on steam. Would not launch on windows 11. Tried to get a refund. But it had been two weeks. Launch d it on my steam deck and it worked great.
That sounds like an issue with Days Gone not Windows. I'm running fedora as my daily but that doesn't change the fact that every game I've played works on Windows out of the box, the same cannot be said for Linux.
He's cherry picking or has some weird edge case issue. I have 20 year old games installed on Windows 11 that run fine. There are no compatibility issues with games on Windows 11
