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?
RISC-V could be a lot better supported then. But I don’t think a lifetime this long would work for the Deck. 7 years is nearly as long as the Switch 1, but that device had the benefit of being a platform in itself with no alternative (as in there are no other switch-compatible-devices). This forces the devs to target it, no matter what performance or fidelity they might wish for.
The Steam Deck might feel a lot like a console, but in the end it is just a PC and the PC gaming world isn’t going to wait for Valves next device. The game-tech will just move on past the steam decks capabilities and a lot of gamers will leave it behind and move to other SteamOS (or windows) compatible hardware. The Deck would still have a lot of value as an indie gaming machine, though.
