I confirm:

• that I haven't found an existing compatibility report for this game.
• that I have checked whether there are updates for my system available.

Symptoms

This bug report is a bit weird to report because there is no crash. What happens is that the game runs at 5fps on Linux with Proton and it runs just fine on Windows.
It seems to allocate too much vram and overload the system. The developer insists that this game can run on lower-end hardware than what I have here and I am inclined to believe him.

This seems to be an issue with proton.

The main menu runs just fine but as soon as we launch a session it seems to overload the GPU.

Reproduction

Install Starship Evo on an Ubuntu system. Launch it, start a new game, lag lag lag.

Start with the attached steam-711980.log and the linked system report gist, then reproduce the issue by launching a new game on the reported Ubuntu 20.04.3 and Proton 6.3.6 setup. Done means identifying or correcting the cause of the severe in-session performance regression and verifying that the game no longer drops to about 5 FPS.
