OK I don't often post here, but after playing with my M1 Max (32-core) for an entire weekend mostly with gaming, here's what I can definitively tell you after benchmarking almost everything I have, including games on Crossover. Mac games have almost always performed worse than on Windows on the same hardware. Anyone who gamed on Bootcamp int he last 15 years can tell you that. So you have to look like for like to see how fast an M1 Max really is.
My M1 Max scores anywhere between 20% and 50% faster than my
Desktop Vega 64 depending on the game. It's not like for like because the CPUs are different, but even under Rosetta (like SoTTR and RoTTR, Civilization etc) it was close to 50% faster in "minimum fps" and 20 - 30% faster on average. This is close to the Geekbench Metal score difference, which is exactly 30% (53000 for my Vega 64 and 68753 for my M1 Max).
3637933 (Vega 64)
3311403 (M1 Max)
Now, in Windows with 2021 drivers, a Vega 64 is about on par with an RTX 2070. So 30% faster than that is pretty much matching a desktop 3070. That's quite incredible.
You can't expect games developed 5 years ago, then ported 3 years ago from Windows to run faster than the very highest spec Windows GPU through emulation on a laptop no developer had even seen until a week ago.
