RE: GPU lockup CP detected.

From watching posted videos, thx lyhon, I've discovered this is not the end boss fight, but instead just after where you take the soured and then the ghosts show the execution of the king. I get several steps out of that room(after crossing under the archway) onto the bridge-like stone walkway and that's where I get the lockup.
It's been commented that the shaders used by Diablo III are inefficient and in this case they used too many temporary variables(registers), leading to a crash of the GPU.
