Apple Gaming Support

Apple have certainly been their own worst enemy in the past with gaming support but I think given they use their own hardware now (GPU specifically) they're in a much better place to support Metal on Apple Silicon for decades if they wish to
So in that sense it is different this time around and I wouldn't write Apple's gaming push off just yet, they're certainly showing a hell of a lot of cool stuff with the game porting toolkit
One of the nice things about apple products is its almost like targeting a console for game devs. All M series have the same GPU architecture and the performance profile for the Mac Mini/MacBook Air with an M1 or M2 or M3 chip is consistent across all M1 chips. So that is a nice benefit in the same way it is when targeting an iOS device. You can quite easily say "M1 or better" for example and have a clear cut off point, etc
And of course you then know a MacBook Pro with more GPU cores performs better but ultimately you're still targeting the same GPU whether its an M1 or an M3 Max the difference is just how well performance scales with higher GPU core count.
