I like the motion blur effect I get in Poser 7, but I'm doing a an 11 frame render of a car flying through the air and it's taking 4 hours per frame (1920X1280 72dpi)!  Any way to get the effect with a little less rendering time?  I'm working on an i7 computer with 12 gigs or ram and an FX3800 quatro so it's not a slow system.
