Not sure if you've seen the other thread on this topic, but basically the GPU being used to drive the UI determines the framerate.
Another user made sure to connect his UI screen to a fast GPU, and moved one of his output screens to the integrated video (Intel HD 3000) and his framerates went from 20fps to 75fps.

Looking to map one giant image across 4 - 6 projectors.
Somehow thought a Mac Pro would do the trick with its 6 outputs. I guess I was wrong.
Could anyone recommend what GPUs I can get to replace my current ones?
I suppose just one much better GPU would do, since Resolume can't utilize two anyway?
My current plan is to use two Matrox DualHeads (which would give me four outputs via two mini-display ports) and use the built-in third out in one card for my preview monitor.
As per my usual habit - all of this needs to happen within two days - and I have a show in a different city to fly to today. Going to be hectic trying to get this all sorted proper.
