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 recently switched to ubuntu in a gaming laptop, right now I’ve been using it just for jellyfin and some other coding tasks, but it definitely runs smoother, more stable, quicker, and cooler than windows did for the same workload.
I was surprised at the difference of even just having the machine idle, on windows it was noticeable warm, now on ubuntu it’s almost as if it has been turned off.
