Hi, Sorry, may be I'm a little off topic/ but my problem also concerns Civilization V. I was trying to run the demo with no success, then I updated my ATI card drivers in the hope of playing it, although now I can watch the intro movie I still cannot run the game, it appears a note "input not supported", I have a ATI 4770 HD series, is this video card not supported for the demo? Any help appreciated, I dont want to spend 50 usd on the game if I need to buy a new card first, thanks.
