In my head I would rather compare it to a Virtual Machine with CPU+GPU passthrough plus optimized Filesystem calls (which gives almost native speed). But I don’t know actually. Proton is very thin layer and focuses only on a few key parts, while the rest of your operating system does all the other things. A Virtual Machine is a more complete and isolated solution, that is less tied to the entire host you run it on (and therefore easier to port presumably). Whatever, I don’t know enough if we should compare it more to Proton or a VM.
I think shadPS4 operates similar, but can’t find a quote on their site or source page.
