The game looks significantly better than the first one and runs basically the same. You can cap at 40fps out of the box, although you should expect slight frame drops in some cutscenes and NPC-heavy areas of the game. The catch is, the game is set to the Low preset and changing any of the settings to medium except for textures does have a noticeable performance penalty which forces to cap at 30fps. I eventually set out to raise some settings (shadows, textures, vegetation, objects), using FSR on the quality setting, which looks roughly like the game's default AA setting (with some artifacts, but not too much considering the game's perspective and rather slow movement) and capping at 30fps. The game looks great and is very stable almost all the time. Some minor drops (25-30fps, rather uncommon) are caused by the CPU regardless and can't really be avoided. The menu does look very blurry however, no matter what resolution you use (even native), which may be a byproduct of the sub-1080p resolution. Battery life is around 2h30 on the Steam Deck OLED. Overall very good experience and definitely very enjoyable on the small screen.
