• 7.0-3: Proton_7.0.3.zip
• experimental-7.0-20220805: Proton_experimental-7.0-20220805.zip

Symptoms

Playing the game on any proton version (using a save-game where there is a lot of stuff on the map and a lot of dinosaurs will yield more effective results, as when you launch the game and play the map, the GPU and CPU utilization will start at high percentages).

As you zoom in close to the ground - the GPU and CPU utilization drops from a certain point and even goes bellow 50% causing the game to run at very low performance even on low settings, the closer you are to the ground. When you zoom out, the utilization goes back up to what it should be when your close to the ground.

This happens with every proton version, EXCEPT Proton 6.3-8 (which is getting the desired rectified performance results for the symptom situations)

Cant use 6.3-8 to play the game because the pause menu does not work on that version, so would really really want this fixed :(

Reproduction

• Play the game on any settings.
• Play the game using any proton version EXCEPT 6.3-8 (which has the desired working performance result).
  (using a save-game where there is a lot of stuff on the map and a lot of dinosaurs. Will yield more effective results, as when you launch the game and play the map, the GPU and CPU utilization will start at high).

Start by reviewing the attached system information and Proton logs for versions 6.3-8, 7.0-3, and experimental-7.0-20220805, then reproduce the zoom-related utilization drop with a populated save. Compare behavior with Proton 6.3-8 and later versions; done means restoring close-ground performance without losing the working pause menu.
