My experience with suspend has not been good - causing glitching and requiring shutting the game down and reloading from a previous save whenever I suspended in a cut scene. As a result I haven’t used it much due to those first couple of trials; maybe it’s better now.
I have noticed a slight reduction in framerates when loading back in from a suspended state but only on certain games. Namely High On Life
I was in the middle of Witcher 3 when I got my deck, and pausing during a cut scene (and some are feature film length, it fells like) caused the video to go slide-show and the audio to get choppy, and there was no recovering the game. I basically had to go back to the previous save and play back to that point. PITA. Something similar happened in one other game (can’t remember at the moment) and I just gave up suspend unless it was something simple / mindless like Yoku’s Island Express.
If you don’t use suspend mid game, what do you do? Do you shut the device down in between gaming sessions? Or do you just save and exit the game and suspend the OS level?
