I think the neural engine works, but you need an out-of-tree kernel module. The asahi wiki talks about that, they say it is yet to be merged on mainline.
Gaming on arm is absolutely a thing... But not on the M's... About the other chips it's just on its infancy right now, fex-emu(https://github.com/szllzs/FEXEMU) and box64(https://github.com/ptitSeb/box64) are both capable of running wine, and of course steam. Games work, I don't think its 100% of native speed, and the compatibility must not be perfect, but like wine/proton I'm sure it's only going to get better.
The apple silicon devices have 16k pages kernels, while x86 is 4k pages, that would not be a problem if we had 4k page emulation/simulation on Linux, but we don't, seems like macOS's way of emulating 4k pages is wasteful to performance, and the contributors do not wish to make a similar implementation, so we don't get one for now.
how the fuck do you even begin making recall a dependency for explorer?
