My agp speed is 8x and im using direct3d, fastwrite is off ( what is fastwrite ) I want to try using opengl. maybe that one will work better than direct3. how do i use opengl?

Is my pc meets the requirements of playing Civ 4? I have low fps and I wish to improve my fps.Thanks for all your help.

In my opinion your PC should be able to run the game fine. I'm guessing that seeing as this is your first post and it's Christmas day you might have got the game today so my first suggestion will be to patch it. You may have already done this but also maybe not. The game initially had a lot of problems with memory leaks and even working at all on some ATI card/driver combos so there's a good chance that patching it will solve your problems.

Check here http://www.civfanatics.com/civ4/patch/ for some mirrors that contain the patch.
