In 32 bit I had 60 in some games that i am playing but after I installed 64 bit I am having massive drop from 60 to 15 I really dont know the problem my system should handle 64 bit.
in case that I need to put my system here:
AMD phenom ii x4 965
4gb ram
GTS450
thanks for help :)
 
Solution
Yeah, you'll have to redownload ALL your drivers and specifically look for the x64 versions of them.
Go to your mobo manufacturer's page, your GPU's your CPU's, and download all the latest x64 drivers they have.
