Hello @flukejones, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/1420#issuecomment-557536992.
Ah cool, I did wonder. @kisak-valve it might be worth putting that in the issue template near the top. I didn't see anything stating as such.
@flukejones I don't know if you are still using this game, but I had the same problem, and finally fixed it with this pull request to berarma/ffbtools (so you'll have to use ffbwrap with the --spam-protection option, or LD_PRELOAD the libffbwrapper library with FFBTOOLS_SPAM_PROTECTION=1)
berarma/ffbtools#17
System Information
I confirm:
Symptoms
Force Feedback appears to work. But then the device FFB queue becomes overloaded, causing either irregular FFB or no FFB.
dmesg
The game otherwise seems to work well with good performance - except for movies not playing.
Reproduction
Play game.
