Re: Technique for videoframe display

Tech-Archive recommends: Fix windows errors by optimizing your registry

This is much too slow. You have to load your image to a texture
surface, and then apply this texture to a primitive (a couple of
triangles that make your rectangular screen). This is much faster that
copying into the backbuffer.
