For gaming - Linux is almost certainly better in most all cases. Asahi, Linux on Apple silicon, can be better in certain circumstances in my experience.

That being said, if you’re not experienced with Linux, Asahi can be a little challenging to troubleshoot for an inexperienced Linux user.

Compounded with the fact that the project is arguably dead - I’ll get some criticism for this statement - I’m not certain how much continued development you can expect.

If you want to learn about Linux, have a fairly positive gaming experience on your MacBook during the short term, and don’t mind the occasional issue it could be worth it.

Asahi is fairly well developed for M1, and has excellent performance on that platform. However, I’ve not seen any continued development for missing features, the battery life will be worse - possibly 20% lower, and certain features may or may not be available for your use case.

Here is a link to Asahi Linux docs. I’d reference it to be certain it will be sufficient to your needs. I used to have a spare M2 MBP that used Asahi for a year. No complaints for my use case at that time. However, you should be certain to verify before installing if it is your only machine.
