Symptoms

Game fails silently - never displays a window. The green Play button in the steam client flickers to blue Stop briefly (0.2 seconds?) then returns to green / Play. Command line output doesn't give me any clues.

Reproduction

In the Steam client, go to properties for Supreme Commander 2
Force the use of Proton Experimental

The same game ran fine with the same settings on 2024-03-05 and maybe 03-06

30 minutes after I posted this, the Supreme Commander 2 game itself somehow got an update via Steam. Now it seems to run fine with proton experimental. So this issue can be deleted or closed.

Closing per the last comment.

Now I think all this was caused by confusion on my part regarding the Steam client global settings and game-level over-rides. Probably nothing to do with Proton. Closing. (er - I would have closed but kisak got there before me.)
