So, im a little confused here... I just got a new computer(not brand new but new for me) and I install medieval 2 total war, while I try to find the best graphics settings for my computer the auto detect moves me up to almost the highest settings, but it lags horribly when I play.

Even when I move everything to mid-low settings it still lags quite a bit. Forgive me since I know very little about computers, but I went to the system requirements lab and found that my computer is supposedly well above the reccomended settings for the game... Is this normal? Here are my specs.

Windows Vista 32 bit

Intel centrino duo 2 ghz, supposedly runs at 3.3 ghz

4 gigabytes of ram

nvidia go 7400 256 mb video memory

Thanks for any advice!
