As many other players, I do not have the possibility to run the game with DX10/11. I have a Vista 32bit system, GTX 280, DX11, latest drivers, but don't have the otion to play in DX11. Now, looking at the path: Documents/My Games/Sid Meirs's Civilization 5, where the configuration/ini files are saved, the GraphicsSettingsDX11.ini is missing! All I have is the GraphicsSettingsDX9. At first I wasn't able to run AA (Anti-Aliasing) neither in DX9, but thanks to Ainwood's fantastic help post I was able to run at least with some nicer graphics as before. Having AA on 8 makes a big difference. So, question is, why can't i use DX11/10. Why is the ini. file for it missing? Is it possible to manually add it? Thanks for your Help!
