> Is that latter case simply due to the availability of high performance GPU cards?

It's a combination of things:

* Apple has not indicated that they'll allow for third-party GPUs

* Apple has not pushed for widespread gaming compatibility

* Game developers prefer to reach the widest audience

Apple would need the M1 successors superior in gaming computation and capable of marrying up to high-performance GPUs, write the drivers necessary AND get broad adoption of Apple gaming to factor into game publishing.

This is all theoretically possible, but it didn't happen while Apple was using roughly the same high-end hardware available to PC gamers, so it's questionable (in my mind) that it'll happen when they are locking down their hardware further, and trying to use all their own hardware for gaming.
