I just upgraded my graphics card from the Geforce 6800 to a GeForce 7900 GT KO. Now first off i CAN run in the environment with all highest settings possible with NO LAG......but when something aggros me like a crab/deer/horse/guard or anything like that.........my fps goes from great to .........well bad. Anyone else have a geforce 7900 gt graphics card that is experiencing something like this??? I am very confused because I even put ALL the settings on the lowest possible with 640-480 resolution AND I STILL LAG when i see something attacking me.....
