i installed driver sweeper
it showd me having nvidia and ati
this is strange i have never had a nvidia on this setup.
so first i remove all the ati ones and install latest one go and do some far cry 2 gaming and no probz
then i selesct the nvidia one like nvidia physx and others then press clean then reboot
and go into farcry 2 and notice objects just apper infront of me and gxf is not as good as before?
Maybe you mobo has some nvidia onboard video chip, for which the drivers included in mobo cd,you have had installed before as necessary drivers for mobo!
After that you would have installed ati drivers for gpu card!
check your mobo specs first
