A few thoughts from someone who has been following the Mac gaming market for decades – I could still be wrong, but here goes.
Some of the main problems when it comes to gaming on the Mac historically I think are due to:
1. For whatever the reason,
the same game performing much worse on the Mac frame rate wise compared to how it runs when started up into Windows on the same hardware.
2. Much
weaker graphics card hardware in Macs compared to what you get for your money on the Windows side of things. Desktop tower graphics cards are much more powerful than what the crammed space in a portable Mac and iMac can offer. It has only been the Mac Pro's that has been capable here, and how much of the Mac market share are those machines? Not that large because of the ”pro” price. There are many ”mid tier” desktop PC
Now, if those two tings could be fixed, i.e. performance of a game on similar hardware (difficult to compare to a Windows PC when the CPU and GPU is different as with Apple's M1 chips, I know) and more capable graphics hardware in the hands of more Mac users – I think gaming on Macs could get at least closer to Windows.
The energy efficiency of Apple's Silicon also makes me feel like Apple
should help make more games choose the Mac – so much potential energy to save.
