You guys need to try out streaming from PC and/or PS5 to Steam Deck. Technically everything runs on the SD in this scenario. I’m playing FF7 Rebirth on the SD via my PS5 right now, and it is glorious. Helldivers 2 via the gaming rig is also pretty sweet.
Steam’s built in Remote Play and Chiaki4Deck are the best!
All of that is true, and makes perfect sense. It all depends on where you live, of course.
