Audio crackle happens twice in 30 hours game time, when it happens you will need to restart the game then the crackling is gone.

It can slow down to low 50 fps for no reason but it's very rare, happened only twice in my 21 hours of play time and for a pixel 2D game it uses quite a lot of battery, on full charge it runs for less than 3 hours and when I try to limit the TDP to 8W it won't even run at 60fps. 4x fps at 5W and 5x fps at 8W.

Turned black screen once, and there was a few times upon quitting the game, the screen turns white with Penitent one avatar on the screen with a loading bar under the avatar. the loading bar stucks over 3 mins, sometimes it does quit the game back to SteamOS interfact, sometimes the loading bar stuck and had to force shutdown steamdeck by holding the power button and power on again.
