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?
ARM boards with slotted RAM use the same type as x86 (although mostly LPDDR, as found in laptops), so I assume there isn’t any difference that is related to the CPU architecture.
