I haven't been able to play a game past 150AD or so because of freeze-ups. The tell-tale sign that trouble is ahead is that the video will get sluggish when moving around, and then I'll get the "Civilization V has stopped working" message. There doesn't seem to be any rhyme or reason to the freezing, no certain number of turns, just around that early AD era. Things I have tried that I can think of: - deleting local content and redownloading the game - updating all drivers - starting in DX9 instead of DX10/11 - lowering graphic settings, all the way to minimum - using small maps with few other civilizations I've attached a DxDiag. Any assistance would be appreciated.
