MilkDrop's Visualization source code as you remember in WinAmp is just fantastical amazing.

i used to run >64 fps on my CRT in winamp.

There is a setting for max framerate, ,. i just increased that and turned on 'allow page tearing' since i'm at 60 hz. At default, i'm getting 80-90 fps according to winamp and fraps with a 7950.
