Hello everyone,
Same problem here - the game freezes after ranged combat is initiated either by a ranged unit or a city, before selecting the target. The game also sometimes freezes during the AI turns - I sometimes cannot see what action AI had taken before the game froze, so I can only guess it was also related to ranged attacks.
This is happening only with DX9, I experience no problems under DX10 / 11 (the game runs faster with DX9 on my older computer, that's why I prefere DX9 to DX10 / 11)
Reading the previous posts from others players, it seems to me the common denominator is that we are all using ATI Radeon graphic cards.
Thank you in advance, Firaxis guys, for sorting this out, I will be playing with DX10 / 11 for now.
