Thanks for the tips guys. The only mentioned here that I haven't used much is the Rasterizer. I'll give it a whirl. Do other renderers have this problem or is it a Mental Ray issue?

Any ray tracing renderer will be slow to motion blur. Renderman is fast because it’s not a ray tracer. Although I think it will ray trace now, although I’d bet if you turn it on the motion blur will suddenly go through the roof.

 

Motion blur, in my experience, isn’t that bad so long as you know how to optimize for it. Remember also that time rendering seems to be more or less proportional to the area of blur visible on screen,j rather more than scene complexity.
