How many lights do you have in your scene?  How big are the shadow maps for the lights?

  Can you post a screen shot of the round globe that shows all of the lights in the scene?

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
