played this on both this pc (specs ->) and the deck, and it worked perfectly ootb start to finish.

Manal gpu clock set to 800, fps locked at 45, tdp limit set to 10.
Works right out of the box with no issues whatsoever! Playing on OLED SD, battery lfe was just over 6 hours on a full charge.
Finished game without issues

Being tabbed out for longer times during certain conversation scenes crashes the game. A minute or three of progress is lost because autosaves work perfectly.
With Vsync disabled and Framerate unlocked, there was a good bit a stutter. Locking the Framerate to 60 works fine.
I switched to Proton-GE to get the intro videos to play, just in case there are more ingame videos later.
Perfect out of the box

The only problem i have found is tabbing out will make the game tab black making it unplayable until restart.
The game tab turns black and is still running but unplayable. Needed to restart.

Seen when brightness is below default (50%), otherwise fine
Only in certain menus (eg. map and title screen)
