I uhh… Don’t really see the point of doing that? In what real-world scenario would you ever rapidly sleep/wake the device?

But here’s a video of me sleeping and waking it again. At 0:03 I push the button for sleep, at 0:08 I push the button for wake.

This isn’t really true. I’ve been playing Sea of Stars on my windows partition on the steam deck. It starts and stops just as well as if I were running it through the SteamOS partition.
