Where abouts can you find this ambient collusion in the control panel?
I too have an NVIDIA card and continously crash on each run of the flashpoints at the end.
Only thing is, mine crashes before even speaking to the guy/ship going into hyperspace.
Any noticeable difference in the game when turning ambient collusions off?
This is an interesting workaround it would be worthwhile compiling what video cards and cpu's people have with this issue, as an example I have a i7 3930k and a 670gtx and have zero issues. this could also be passed back to nvidia if it seems to be a particular series of cards with ambient occlusion issues
