question about fps

60hz / 60 FPS is what most (if not all?) NTSC consoles will run at internally, regardless of how many frames per second they're putting out graphically. This is why if you are running a game (such as Zelda: Twilight Princess) at 30FPS, it seems to be half-speed, even though the game only runs at 30FPS. It'd be nice to get around this (if the 30FPS limit is your GPU's problem and not the CPU's, dolphin should be coded to allow the CPU to run at 2x the GPU's rate, kind of what the GC/WII do from my understanding is just redisplay the old frame 2 times in a row to achieve 30FPS, that way the CPU/GPU can remain busy for an extra frame to do work that would otherwise make the game choppy at 60FPS). I get about "50 FPS" in Twilight Princess, and it doesn't run quite at full speed. The game is probably rendering 25FPS at that point.
