I don't have the fastest ARM machine in the world, but arguably the most open (a MNT Reform laptop) and I was very pleased to see how advanced Linux ARM support is now when I first got it. With a few exceptions, there's essentially zero things you can do on amd64 that you can't do on aarch.
And since the only games that interest me are more or less turn of the century or older, it's plenty fast enough for my gaming needs.
