The only model tested that could hit 60fps+, (and only at 1080p, at that) was the 40-core M3 Max MacBook Pro 48GB, which is still selling for between $2,500 and $4,000 (!), despite being last generation hardware. And it was still only able to hit those 105fps at 1080p through upscaling, which is usually the kind of resolution you upscale
from, not to. The lower the base resolution, the less visual detail the upscaler has to work with, after all.
Anyway, that's a pretty small demographic to begin with for publishers to justify spending the money on a port for, especially with the majority of those users likely to have it as a work machine, and therefore being unlikely to be playing games on it.
None of the MacBooks that are actually out there in significant numbers, among people who might actually want to play games on one, are actually capable of doing so.
If you can afford to buy a M3 Max MacBook Pro for personal use, you aren't going to be satisfied playing at 1080p in 2025 like some sort of PS4 peasant, anyway. And, for the same price, you can get an incredibly beefy gaming PC that will actually deliver the kind of performance that you, as a fancy-pants top-end MacBook Pro user, are likely to demand and expect.
