There's been some recent big budget games compiled for Apple Silicon; Lies of P and Baldur's Gate 3 come to mind. Of course, that's just a tiny fraction of big budget games and I haven't actually played any of them to know how good the experience is.
I've been playing BG3 on an m1 Mac mini and it's surprisingly good. I haven't bothered loading it on my big-GPU gaming PC to compare, but that alone says something.
(I'm in no way a serious gamer, so there may be plenty of things I overlook)
It's nice when it works, but papercuts still degrade the experience. The M-series chips are really impressive when they get a chance to stretch their legs. It feels like we're still in the chicken-and-egg phase though. I don't foresee that changing unless Apple dumps a ton of money to incentivize publishers to port to Mac, or they do what Valve did and make their own equivalent of Proton - aimed at developers. The licensing on GPTK kinda kills that though.
There is some gui software that would be nice to run on linux, but none mase by apple.
