GPUFractal-3

More fuel for the Cg vs GLSL debate: I sent the link to the creator of Ultra Fractal and he asked about calculation speed, so I told the program to redraw as fast as possible and turned off vsync in the control panel. A 1024x768 image, Smooth outside and None inside, runs at 82 FPS under Cg on this machine - an NVIDIA 8800 GTX with a 2.66 GHz Intel Dual Core processor on Windows Vista, everything up to date. Under GLSL, the same image runs at 131 FPS, 59% faster. I think it's safe to say that GLSL has eclipsed Cg when doing hardcore numbers of operations on NVIDIA hardware, and even so I know the GLSL optimiser is pretty poor.
