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.
My wife’s laptop crapped out so I threw pop os (previously had arch on it) and made profiles for both of us. Lets her play the few games that she likes, and Firefox is the same. It’s made for an easy transition from windows to Linux for her. Ubuntu would probably be just as easy overall, but she likes the tiling too since it’s very helpful on a small screen (arch + bspwm is my main driver so I wasn’t going to give up tiling)
