--- Comment #12 from Henri Verbeet hverbeet@gmail.com --- I think I can mostly reproduce this, although I don't have an exact fps count. The profiler claims about 30% of CPU time is spent in DSOUND_mixthread(), which seems excessive, and only very little in D3D code. My guess would be that this is more of a sound issue.
