Has anyone experienced performance drops with the Nvidia 331.65 driver?

With my previous drivers I could run ultra at about 70-80 FPS, but now from ultra all the way to low I get contsant peaks and troughs in my fps from over 100 to less than 30. This happens regardless of my graphics settings.

Has anyone else experienced this? And more importantly, is there a fix?

My system is running 64-bit Windows 7, I7 3.4GHz quad core, 16GB of ram and a brand new GTX 770.

I just purchased it and installed the driver but I get fps drop aswell..

780 here. No problems for me with that driver.

I’m installing the new driver, and about to buy bf4 as soon as its done…should I wait to avoid the problems?? Lol…T_T

Can add that the 331.65 is working excellent on W8.1

I’m not sure if the latest client patch or the driver is to blame for me. Def. went from 60-80 fps to 30- 50. win 7 64b, 560ti
