Nobara OS, Arch Linux and Pop!_OS beat Windows 11 by a slim margin in fps (delta 8) in Windows native games - Cyberpunk 2077, Forspoken, Starfield and The Talos Principle II. Windows 11 wins in Rachet & Clank.
ComputerBase’s testing was done on an all-AMD test rig, featuring a Ryzen 7 5800X (non-3D) and a Radeon RX 6700 XT.
Update: Windows 11 wins in one game.
I agree to an extent, but most games just work in Linux with no slowdowns or glitches. And I’ve had to mess with many games in Windows over the years to get them to run.
