After accessing the link provided, it told me that i already have the update installed. It is weird. This win7 is 2 weeks fresh. I updated it after the installation. Reading the forums i thought that my Dx is old or not updated. Looks like im good on that subject. I still get low frame-rates on the beta, and my friend with a gtx 660 has the same problem. Hope they will fix this soon so I can upgrade my system.
