Wanted to talk about this a bit. I’ve seen some things showing how well along translation layers have gotten with both proton from windows based games and x86 apps running on ARM. I think it’d be a huge improvement for something like standby time. Although I’m not sure how well it’d be for power efficiency while gaming since it might use the same amount of power for similar performance regardless. Maybe better for low complexity games like balatro or vampire survivors?
I don’t think so, Valve already have their hands full with one translation layer and probably don’t want to add another layer on top of it.
I also wouldn’t be surprised if battery life ends up being worse through the hypothetical vm. It still has to do the same amount of work after all.
