Oh dear, i've got my new nvidia 8500gt 512mb graphics card with latest drivers and whilst gameplay has improved, it is still poor, jittery very stop start. I have the latest drivers, direct x, ive disabled pretty much everything! i've also played around with lower resolutions etc. since first typing this it has got slightly better with the tweaks but still not good enough to play.
anyone know what else i can do? i was assured that my system would be ok with this upgrade so i must be doing something wrong?! please help!
