Take a prod at the the "pcb+gl_experimental" branch.
That should be faster than git HEAD, as it uses a much more efficient way of rendering the polygons...
It uses rasteriser code borrowed from Cairo for complex shapes, and has a few other little tricks to keep things fast. It short-cuts rendering circular holes in polygons by using a pixel shader.
Have you tried any of my OpenGL branches?
