The further into the game you get the more it seems to struggle, I believe this is on the game itself.

The game works right out of the box! But as you progress through the game, it becomes more demanding for the steam deck hardware.
Setting the resolution below 720p and capping the FPS to 30 increases the battery life by an hour at best.
Low-resolution textures render the text quite difficult to read.
As you advance through the game and aquire more paleofolks, the open-ended zone becomes way too taxxing on the steam deck hardware, often dipping to 18-23 fps. Even with all of the graphical and resolution settings set to low (textures set to quatar for readability) it doesn't make any significent improvements.
The shop gameplay, which requires quick responsiveness, performs adequately at around 35-40 fps. Fortunately, no other aspect of the game demands such high responsiveness.
However, if you desire a consistently smooth experience, it's advisable to wait for a few patches to resolve performance issues or for the developers to introduce low-polygon model options.

Changed to 30FPS to improve battery
If you are experiencing slowdown in the larger area:
- Reduce FPS to 30
- Change texutre quality to Quarter
