Forceware 91.47 and BF2

Over the weekend I decided to install Nvidia's latest driver, but i seem to have a few troubles but only in BF2.

Its mainly down to Jerkiness yet i havent changed any settings from the previously installed drivers. I refuse to lower my settings but wondered if anyone else has had similar issues in BF2?

Also, how do i get the overclocking tab exposed in the new Driver? I had given the Card a Mild overclock in the previously installed drivers, but not to the extent which would make a difference beetween Jerkiness and no Jerkiness.

Thanks in advance for your Answers...

delete the existing cached video/texture/shader files in your my documents folder and BF2 should rebuild the cache the next time you load a map.

My cache is at:

C:\Documents and Settings\USERNAME\My Documents\Battlefield 2\mods\bf2\cache

Bascially delete everything in that folder (there may be several sub folders but it is safe to delete them all.)
