I still have this problem when playing video to image and using NGC Collision.
Here is test code, use any avi or mpg video on line 43 and change your NCG keys to line 28.
When switching NGC Collision on and off FPS varies between 80 and 5 ! I have tested this code in half dozen computers, all act same.
I use Ellip to Poly collision, but it cant be so slow. Or whats wrong?
