Emulator

The problem is that frameskip doesn't really work.

Frameskip works well for older emulators older older consoles (Such as NES/SNES) on older computers, where the emulation of the CPU took very little time compared generating the graphics or in some cases moving the graphics to the host's GPU across the slow ISA/PCI bus.

But dolphin is mostly CPU bound, and we now have dedicated GPUs to handle the rendering of the graphics, so GPU rendering time doesn't really cut into our CPU emulation time.

Dolphin's frameskip code is old, un-maintained and doesn't work. It just pollutes our video code without giving us any benefit. Sure it could be improved to a working standard, but even then it would still be next to useless.
