riddleofsteel: I just tried TA in my Windows 7 x64 install and I ran a battle at 1920x1200. I get a strange black flicker every couple of seconds. Does this happen to anyone else? I thought it might have to do with my having triple buffering and vsync forced globally but turning it off didn't help. Thanks for any ideas. I do have a dual gpu card, that might be the problem.
I'm not sure if I was seeing the same thing, but...
Last night I broke down and bought the game. Ramped the resolution up to 1680 x 1050. Playing the first Core mission in the main campaign, I would get crazy flickering sometimes, and I realized it was because the starting map was basically the size of my horizontal resolution. The camera was freaking out, trying to fit a view of the map into a space nearly the same size as the map. When I would scroll carefully, I could remove the effect (though if I scrolled too close to the edge the flickering would resume).
While I know basically every map in the game is larger than the initial missions' maps, I decided to reduce the resolution a little just to be safe, to 1440 x 900. Works fine with no flickering.
