This isn't gloating, but so far I've had no problems with CTD'ing out of missions or the like, and I'm finding this to be a great purchase. I say this merely to highlight that the problems you experience may be limited to particular hardware configurations or combinations, or some other combination of factors and are by no means universal. That doesn't make them any less real or frustrating for you of course, but might shed light on why there are not instant answers from ED.
