I have never had an issue with standby playing steam games, third party launcher games and even emulated games. Not saying it can't happen, byt it was the same with PS5. Some people had one bad experience and refuse to use standby to this day.I can count on one hand how many times I've had an issue with suspend/resume on steam deck. And I frequently will suspend and resume anywhere from a few times to a dozen+ times per day when I use my deck. I even leave it suspended for days at a time, full weekends without any use and when I resume on Monday, I'm right where I left off. It's incredibly reliable
