Every time I try to play through a game of GW the game bugges out. Three times in a row after like the 5th or 6th battle, at some point during combat the screen turns a shade of green-blue and the whole world dissapears. All the UI control widgets are still there, but where there should be a planet and armies instead I just see greenish blue. I can still hear my base getting blow the heck up, and when I randomly click around the screen I can select units and give them commands, but I cannot see what Im telling them to do or whats happening to them. Replicability: Every. Single. Time.
Most likely this is an issue with the graphics driver. You might want to try updating those. PA is very sensitive to running the absolute latest version of the drivers for your graphics card. Use beta drivers if you have to. You can post you DxDiag.txt here for more help. Instruction stolen from SXX:
