The Fast Panorama is rendering each image separately, it looks like. So the nice seam- blending is missing. It is possible you might reproduce some of the blending in an OpenGL programmable shader, but doing the smart seams is an unknown and would require creative development.
Another possibility is the OpenMP build of enblend, which uses modern processor optimizations. I'm not sure if it's using OpenCL as well, which would use your GPU for appropriate parallel computation. Just some suggestions to go look for more info... The biggest speed savings is reducing resolution. How far can you limit it? It sounds like you are not trying to do responsive rendering, so a two-pass render, once at low resolution followed by a high resolution final pass, is not interesting?
