--- Comment #6 from darkskyabove darkskyabove@gmx.com --- The triangle hell appears to be tied to gibs from corpses. (And I'm now using a player with all the Bloody Mess perks so I tend to create lots o' gibs.) Still random bug; not all corpse events cause audio problem, audio problem can occur with no overt activity (rain seems to increase probability).
I'll do some more tinkering like setting iPresentInterval = 0 to unlock framerate.
@tim110011: There are many "easier" ways to trigger bug, but that one sounds like a 100%-er, so thanks. Will not be downgrading my nVidia.
