Alright, lets see what we can do. First, you say your drivers are up to date. Thats good. Next, get the latest version of Visual c++ and directx web updater. Those are commonly missed parts of a fresh install.
Also, its possible that your GPU isn't kicking into high performance mode even though you set it to. Switch your backend to OpenGL and enable the vertex streaming hack to start (its under graphics > hacks, and only visible for OpenGL)
Make sure you're using the latest dev build.
