Why does this crash?

[bplus]

BTW, did Order and Chaos run on your computer ok? What were your frame rates?

Yes just checked it out.

HW ran ~ 500 FPS but every time I restarted with spacebar the speed dropped, did not stay with it to see how low it would go but putting picture back together ran again at ~ 500 FPS then spacebar shatter a lower FPS then bak again at 500....

SW ran ~150 and if it dropped after a new spacebar shatter it wasn't nearly as noticeable as it was with hardware.
