I had Cyberpunk on my Steam Deck when I put it to sleep a couple days ago. I turned it on today, having totally forgot I was in game. I stared at a nightclub on my screen, dumbfounded, as I was expecting the main menu.
I hadn’t even paused the game when I put my Deck to sleep. I just hit the power button and could play instantly. I still had 30% charge from having played earlier because I didn’t even plug the thing in.
What a total shock.
Oh yeah. Comes very handy for games like Armored Core, where you get super far into a level then have to go, but can’t save your progress manually. Just put it in sleep mode 😊
