--- Comment #10 from Kai Krakow kai@kaishome.de --- Pulseaudio just uses the OS defaults...
But before nagging the freedesktop guys, under the assumption that my comment was constructed from memories, can anyone confirm that disabling pulseaudio or reducing shm size improves the situation?
I've also read that debug info in a compiled wine distribution can introduce memory overhead. Thus I recompiled my own version without debug info. But I currently don't play 32 bit titles that expose this problem, so I cannot currently check this.
My own version is here (includes Proton): https://github.com/kakra/wine-proton/releases
Some of the 32-bit memory issues are documented, and I collected commits around this problem to mitigate those problems: https://github.com/kakra/wine-proton/blob/rebase/proton_3.16/README.md
