I have been playing Civ4 for quite some time now. My brother and I have spent many nights playing hot-seat games for hours upon hours. For some reason the game has really slowed down. It is to the point where it is unplayable. It almost seems as though my graphics card has ran out of energy. The game just really lags now. I did not change anything. I just can't figure out why all of a sudden the game performance has gone down the tubes. I just recently added another GIG of RAM to see if this would help. My laptop now has 2GB of RAM in it and still has the same laggy/choppy gameplay. Can a graphics card in a laptop get "tired"? The laptop is a few years old now and it only has an NVIDIA 64MB card in it but it worked flawlessly for over a year with Civ4. Is there anything I can try or change? I am getting desparate to get Civ4 back up and running to the way it was. Any information/help/suggestions would be appreciated. The only thing I can think of is I noticed at the time when I installed NHL07 the game seemed to start its laggy play. I have since then uninstalled this game to see if I can get Civ4 back running again. Didn't work! I'm just not sure what else to try. One other thing. Galciv2 ran great in the past also but it started with the choppy/laggy play right around the same time Civ4 started with the issues. What should I do?
