I installed Civilization 4: Colonization for my computer yesterday and today when i play it it kind of lags. when moving the cursor to another city or moving the screen view it lags and takes a few second for it to adjust. same thing when I end my turn, it takes a few second for the END TURN globe thing to go green again and it takes a few more seconds after for it to move to the active character. I played a flash game called "SWORDS AND SANDALS" today as well and that was laggy as well with the gladiators attacks and movements. Same thing with Runescape it lags a little bit. I don't thing its my graphics card cause I played the other Civilization 4 ones like Beyond The Sword. I got 5200 GeForce, 512 mb RAM, 3.0E
