Hi Prash
I was on Driver 331.65 when the render bar issue started with me
. I updated to 331.82 and PD11 started to crash right away , so i installed PD11 again to remove the update that i downloaded for PD11 , then i installed driver 320.49
and everything went back to normal
. Im gonna install the update for PD11 again later this evening and see how things go.
Im using a window 7 64 bit .
Video card Nvidia GTX 660 TI .
Later
Mohammad .
