I'm running 6111, and Axel's latest build has OpenGL sync enabled. Playback 
was absolutely horrid on every channel, like ABC used to be. Musta done 
something wrong there... I rebuilt with it off for the moment, but I'll try 
enabling it again later (I probably ought to stfmla first).

Perms changed, 1024 echoed, off to do some more testing.

Nope, everything runs okay w/bob, and cpu usage is actually lower than w/what 
I normally use (linear blend). Lemme double-check that though, I've tried so 
many different things, I may have that wrong.
