Comment on Valve is working on a version of proton for ARM devices
Fubarberry@sopuli.xyz 2 weeks agoAlso, does ARM still have better battery life when all of the machine code has to be translated from x86? That adds a not insubstantial amount of CPU overhead, which does hurt battery life.
No idea, and that’s a pretty good question. The again some games run better on proton through Linux than they do on windows, so the performance overhead isn’t that bad.

True, but I feel like having to reroute x86 calls to ARM will produce more overhead than just Proton.

Depends on how it’s implemented. If they have a version of Proton that translates all x86 windows syscalls to ARM Linux, some operations could be extremely efficient.
There’s definitely got to be more overhead overall, though. Especially for devices with memory page sizes other than 4K, like the M-series Apple chips do (they use 16K as their page size), likely a VM will need to be sandwiched in there to ensure memory alignment. It’ll more fully be emulation and not just translation.
