A fast trick to do motion blur in OpenGL is to draw a black, translucent texture on top of your scene (don''t clear the screen every time you draw the scene). This is the method I use and it has very little impact on framerate.

Yes, this is a very witty signature.

Yeah, but that is not true motion blur. See this page:

Actually, as of now, motion blur is GENERALLY pretty slow... Real-time I''m talking about.
