Yeah. My game is also "freezing" on battle openings if the graphic settings are set above the minimum. My computer is: Intel core 2 duo 2.93 GHz, 4 GB memory, NVidea GeForce 9400 GT 1GB.
The first error of this I found is on the tutorial first battle as my Corvettes and Arks enter the system with Klurgu. The battle opens to star field(not the planet) and the screen won't scroll(no ships visible). The battle will proceed but it is not visible because the ships are at planet which is not on screen. I can pause or resume it. I can end battle and proceed with game. Sometimes the game will freeze after the errored combat.
This can all be worked around by restarting the saved game with graphics set at low. I tried mid range settings also but the same error happens.
I will try the debug as explained by Erik and post another time if I get the degug list.
