There is a reason nVidia has generally won the consumer GPU arms race over the years over AMD. They go out of their way to support studios and titles, compared to what AMD does imho.
It shows that Apple recognizes it needs to lower the barrier of entry for studios to considering targeting Macs. Because compared to the larger gaming market most studios have very little incentive to build and maintain this because Mac’s could account for 1-3% of your player base. Is that worth 1-5 ICs worth of time if you are a small studio. Probably not.
