I actually used to run some of the highest settings at 120 FPS on my M1 iPad Pro. One of the recent patches has severely affected my performance such that I can’t turn on much and still have 60 FPS now.I’m honestly not sure.
I’ve tracked Mihoyo’s tweaks between 2.0 - 2.5 from an end-user perspective, and they obviously tried at least somewhat but I’m not sure if they actually took a look at specifically M1 devices.
Because whichever way you look at it, the game runs badly in extended gaming sessions.
I’m not sure if it’s the heat factor of the M1 being shoved into a thin metal slate (from what I’ve seen, M1 Airs suffer from similar problems too so that may be an unsolvable issue) or if it’s Unity’s propensity to overheat devices, or if Mihoyo just can’t be bothered to optimize it further… difficult to say.
But I’m pretty sure that there will be a limit to what can reasonably be done with that chip due to how much it heats up, and it probably won’t be anywhere close to the highest settings they offer in the game. I hope that I’m proved wrong though.
