Civilization 4 100% CPU usage

[johnation33]

Hi, I own Civilization 4 with patch 1.61 installed but the game uses 100% CPU usage and the framerate stutters... the game goes from 35% usage to 100% usage and then back again--this vicious cycle keeps repeating, and it takes away the joy from the game.

I use a mobility Radeon 9600 Pro Turbo Video Card and I have a 2GHZ Intel Mobility Centrino Processor.

I tried lowering all the settings to the lowest settings but it seems to have no effect. Anyone has a solution for this? Thanks!

Not uncommon. Try clamping the framerate using the Civ4.ini file, look for the line:

; Set max frame rate clamp (0 means none)
SetMaxFrameRate = 40

Try different framerates until you find a decent setting, it should lower the CPU usage without sluttering too much.
