Note: there's a difference in the settings and behaviour of the logs using 5.0-{3,4}, and I believe they are related. In the first one for each, the game is being run with the "Steam Input Per-Game Setting" set to "Use your global Steam Input settings (Xbox)". This was unintentional for the very first log I made (5.0-4), but I changed it to "Forced off" when I realized that the controller wasn't recognized in the game. Curiously, when it wasn't set to "Forced off", the game ran without stuttering, but as soon as I changed it back to that it started stuttering again. I don't know exactly what's going on here, but I do find it interesting.

Symptoms

I have two choices with the game presently:

1. Extreme stuttering that makes the game unplayable (5.0-4, 5.0-3, 4.11-13)
2. Unrecognized/incorrectly mapped controller (4.2-9, 3.16-9)

Reproduction

1. Choose any of the mentioned Proton versions
   a) Set "Steam Input Per-Game Setting" to "Forced off" or "Use your global Steam Input settings (Xbox)" for your choice of unplayable stuttering or unrecognized controller respectively if using >= 4.11-13
2. Start the game
