Symptoms

Game throws the error "Available memory is less than 15mb"

• Game closes

Mitigation / Resolution

• Open game properties
• Go to Compatibility
• Force the use of a specific steam play compatibility tool

• Game now launches

I shouldn't have to do this to get the game to run. I'm aware there are also "unofficial patches" to get this game to run, but people can still pay £15 for this game on Steam, and it is unplayable on the Steam Deck because of this error.

There either needs to be some form of regression (is that the right word?) to incorporate why it works with the older proton version, or it should include the unofficial fix.

Here's the proton log when running with proton 3.7-8:

Hello @syberphunk, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to #1804 (comment).
