Bug ID: 44783 Summary: Jedi Knight Dark Forces II/Mysteries of the Sith, choppy audio causing very poor performance Product: Wine Version: 3.4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: libsanorec@hotmail.com Distribution: ---
After a somewhat recent upgrade in Wine (don't remember from what version though, but it was a very old one), I've been having problems with audio in both JK and MotS, where sounds playing in-game will lower fps significantly and sound very choppy.
In Jedi Knight, causing sounds to play continuously (say, by firing a very fast gun right into a wall) will cause the framerate to drop drastically, from the usual already very low average of 30fps to around 10fps. Needless to say, the sound will become increasingly choppy the lower the framerate is. The problem is less present but still there when playing the game without 3d Acceleration, and the average FPS is a lot higher as well.
I normally use JACK audio with a Pulse Audio module, but having JACK on or off doesn't seem to make any difference in game performance. Changing the Wine audio driver to winealsa or winepulse also didn't have any noticeable difference. I however did not experience any such performance drops when running the game with Wine audio disabled.
Running from console won't cause any error or "fixme" messages to print when choppiness happens.
In MotS the problem is even worse: audio choppiness happens in almost every frame, leading to short freezes and overall complete unplayability. I believe this might have something to do with the sample rate for the sounds in these games: JK uses 22050Hz and MotS uses 11025Hz.
After resetting the ".wine" directory, overall performance seems much better (still around 30fps, but far more stable), but the audio is still very choppy.
