Even on the highest settings, the game will happily chug along at at least 45fps, and you'll get 3+ hours on the OLED. There were a couple of areas where the framerate dropped (to mid 20s), quite uncharacteristically, in the forest region, as if the game were trying to render the whole thing. This doesn't affect gameplay too much as you're just running from one place to another.
I tried limiting TDP and GPU to try and get more battery time, but parring down both to 10 and 1000 respectiveley didn't seem to affect performance or battery, so I left them at default, as they game seems to draw what it needs.

The game runs well out of the box. It must have received a Steam Deck specific update because no granular settings are available and instead the game offers a performance and quality mode. The difference in visual quality is rather minimal between the two due to the game's art style, so I advise sticking with performance mode, which runs at 60fps 90% of the time. There are some frame drops in more open and visually complex area, but since they only serve as hubs between the titular dungeons, the core gameplay is unaffected. Capping at 40fps removes these drops completely. Overall a very decent experience.

Pretty stuttery, beginning with the area after the tutorial.
Performance out of the box is not good.

Great game, played with no errors ever. Finished in 21 hours. It is a battery suck, but I saw almost no FPS drops. I reckon there are ways to make it do better on battery, but I didn't look into it.

Lowered the settings and limited it to 40hz
I once had frame drops, but it got normal after a few seconds, and it was just in one specific place
High settings run with relatively high FPS. For a stable 60 I would still recommend lowering some settings (shouldn't take a lot). I just limited it to 40Hz, Low settings, turned up Texture and shadows for a longer battery life
