Some additional info:
The (very) bad OpenGL performance (rendertime of >1500ms) you are experiencing could also come from using the wrong (MS) drivers.
Have you tried the Intel drivers?

Intel's drivers should supply hardware acceleration and better feature support, the MS ones often only supply software rendering, Or are you on a virtual machine?
