Question about Mac gaming. (opens in new tab)

Ok, so I get Mac gaming isn’t the best, but I was looking at benchmark scores and they do really well. So like a 5070 ti (mobile) gets about 1800 in steel nomad, a M4 Max 32 core gets about 3000. But in actual games it’s nowhere near a 5070 ti, even in Mac arm native games. So is it just a really crappy software design or bad supporting development or something? It seems like the hardware is more than capable.
