If you have some monster like 3090, you expect it to run games smoothly on “ultra” settings. In reality, some games are pushing its limits even on “middle” settings (Cyberpunk 2077 @ 2k, RDR2 @ 4k). Any emulator will hit performance, so if you want some top-of-the-top performance - you still need Windows PC with RTX 3090. And it will not be even more expensive than Mac Studio ;)
