Hi everyone...

This time, I'd like some ideas about why my prog could slow down AWFULLY when it's running under an older videocard. It has been tested on a GeForce2 MX machine with a dual 3.x GHz P4 CPU, and it couldn't even stay above 25FPS... On my 2GHz system with a Radeon 9700 I can't get it above 10% CPU even with the DirectShow decoded HE-AAC music on...

The cards I've tested it on and was crapped as hell: Savage4, TNT2, GeForce2MX

The cards I've tested it to work on: Radeon 9600, 9700, GeForce 4 4400, and some GeForce FX... 5600 I think...

Ideas, suggestions, anything?
