Windows 8 Performance Drop
So I upgraded to Windows 8 64bit a month ago, and my gaming performance has dropped ever since then. I have a gt650M, so I know that isn't a problem. I didn't do a clean install; I did the upgrade via the assistant. For instance, Just Cause 2 stutters, whereas in 7 it didn't. My nVidia drivers are up to date as well. This is really irritating me. Any suggestions?
