I am using the latest Nvidia drivers but that boost still happened strangely enough. Just the rename made my game run butter smooth. I have an i7 3770 3.4 ghz and a GTX 660 1.5 GB and 32 GB of RAM. I had read on forums that the rename have a huge FPS boost, and I can confirm it's a world of difference. It went from horribly stutters to barely any streaming to butter smooth and no pop in.
