I know about the vbeam speed hack, and from what I understood, it isn't really overclocking the emulated GPU.
anyway, I have been wandering, why there is an option to overclock the CPU and not the GPU? The option really helps and I use it, but I'm sure that some games can be also GPU limited (For example, I tested Super Mario Galxy with 125% CPU and 250%, and my framerate was the same. I know the games runs at 99% 60 fps on the real wii if not 100% but it still makes me think the game is more GPU limited on the real Wii). It really makes me wonder what would be the performance impact of both actual game speed and emulated game speed with emulated GPU overclock. And yes, I know that unlike today, in the past games on both PCs and consoles had more CPU bottlenecks.
