Did some benchmarks comparings Linux vs Windows out of curiosity.
Setup:
CPU: Ryzen 5 5600x stock
GPU: 3060 Ti
RAM: 32GB 3600MHz
Resolution 1080p
Config: Mastercomfig Medium-low
Dx9
benchmark1 Win 11
2639 frames 7.854 seconds 336.03 fps ( 2.98 ms/f) 35.471 fps variability
benchmark1 Arch Linux
2639 frames 7.241 seconds 364.43 fps ( 2.74 ms/f) 35.418 fps variability
While the raw performance seems to be better on Linux, the actual gameplay is more stable on Windows 11 on my machine. Now and then the frames break into the 140-160s for a few seconds in actual gameplay on my linux installation.
