There are many reasons, but here are the biggest ones from my time using Nobara OS:
1. 1% lows are better on linux, giving every game a smoother feel, especially apex.
2. No micro sutters or screen tearing issues that I had on Windows. Micro stutters every 5 or so seconds that made the game extremely frustrating to play sometimes.
3. Microsoft doesn't respect their users and is forcing spyware onto their computers through copilot and recall.
4. Dual booting is a major nuisance on top of the fact that when I did used to dual boot, windows deleted the boot partition for Nobara.
5. Linux is faster, more responsive and has native support for higher polling rate devices.
6. I simply just prefer Nobara over windows.
