I have the following: 1.3Ghz processor 192MB Ram memory 80GS HD w/7200RPM and 8MB cache 16MB video memory? etc Whenever I play need for speed hot pursuit II, the computer lags. The picture does not go smoothly at all. the fps is pretty weak. When I upgraded my HD to the 7200RPM HD, it was a bit better, but still not smooth. What can I do to make it smoother? Graphic accelerator? more Ram memory (possibly 256MB more)? help!
