Quote - right, same mode.  that doesn't mean it's the same.  i know the preview changed from P6 to P7 to add more features.  i don't know if it changed from P7 to P8.  but i'd bet the simpler preview modes haven't changed.

I am dubious as to how this could make such a large difference.  To me it's more likely some random element of the simulation just required more math to be done, and re-running it a bunch of times would likely come up with different times to complete for each ^^  Hard to say.
