No problems at all

Frequently slightly drops from 60fps (at 1200 x 800) when fire effects are on screen. Seems to occur regardless of resolution.
After changing resolution in Windowed mode, apply had to be pressed once and then again afterwards to properly scale to the new chosen resolution.
Frequently slightly drops from 60fps (at 1200 x 800) when fire effects are on screen. Seems to occur regardless of resolution. Shooting the shotgun and some other weapons also causes some minor drops, especially when shot into snow (bringing up snow effects). Not sure why these occur. It's playable, but far from ideal. The drops aren't major, but the game is sort of inconsistently choppy as a result, to the point I'm choosing to play the rest of this on my PC.
It works.

Custom launch arguments above were required in order for the game to use my dedicated NVIDIA GPU instead of the integrated Intel GPU.

D3D11 fixes fps issues but pegs a CPU thread to 100%, use 9W TDP limit + manual GPU clock or 2GHz CPU cap to limit battery drain
+r_rhirenderfamily d3d11
TDP 9W + Manual GP Clock 1000 Mhz
Framerate seems to be a stable 60FPS at 800p max settings with a TDP of 9W with a manual GPU clock of 1000 MHz, although I haven't played enough of the game to be sure.
Alternatively use the decky plugin PowerTools to set the frequency limit of the CPU to 2GHz
By default, ambient occlusion is set to high. This setting makes the framerate dip from 60 to 30 consistently whenever you look at a particular light source. If you want to leave the setting on, the deck can handle it at a solid 30 fps in my experience. Otherwise each of the other values (low and medium) seem to still cause framerate drops albeit less intense. I personally have AO off completely and it makes my game perform at a stable 60 fps.
V-Sync is on by default. It seems to half my frame rate with it on. I would recommend turn it off.

locked to 40 to save battery

Works out of the box
Runs as expected without problems, no tinkering needed
