Hmm, it might be the intel drivers - I don't believe I'm doing anything out of the ordinary with rendering things... Do you possibly have another OS on that computer that you could test with?
Also, I've updated with a new build that allows you to bring up the profiler using the 1 key - can you download and run the build, enable the profiler, and take a screenshot of the FPS, profiler values, and OpenGL information (all in the same place, top-left corner box)?
