Flawless it runs insanely smooth 12/10
Black bars on top and bottom distorted on rare occasion when opening the map, did not affect gameplay.
Runs out of the box, Epic Store version, installed by Heroic Launcher, 100 % stable, no problems or glitches.
Full playthrough with no issues
Works perfectly (with a couple of in-game settings tweaks)
There is artifacting at the top and bottom letterboxed edges of the screen on Steam Deck by default (this is probably why it's Unverified on Steam). This is completely eliminated by switching to Windowed mode (does not affect how the game is displayed in Game Mode). You might as well set it to 720p as well for better picture quality on Steam Deck as well, as it defaults to 1080p.
Finished game without issues
16:9 only. The black bars sometimes glitch out.
Sometimes when waking up from sleep, it took up to 30 seconds for the controller to react
Pretty stuttery, even when lowering the resolution
Starts in 1920x1080, for whatever reason. Frequent stutter is annoying, but it's playable
