Even if they did, there is very little in Apple Arcade which taxes the GPU, most target the lowest common denominator in terms of supported iOS/phone combinations.
The original Apple Arcade strategy was for AAA titles, but for whatever reason that wasn’t pursued, so now we have a tonne of casual games and re-releases of old titles.
Apple just seems to run hot and cold on gaming.
Can you prove that statement? I bet you can't, cause it's simply not true. Every Arcade title is playable from an iPhone to a Mac by way of Apple TV. It was never going to get AAA titles.
I own almost every Apple device in the ecosystem, but I never game on them…
Apple wants more Grindstones.
There’s no correlation.
