I know. Just tested on 3.16ghz. My settings are x64, dual core ON, 640x480, but am using standard windows build downloadable from dolphin site, which is older than your custom build. Still, I got ~23fps right there without moving Mario, while only ~26fps on 3.6ghz. Also my cpu wasnt fully loaded, I got 1 core at about 95% under 3.15ghz and about 85% under 3.6ghz and second was always somewhere around 50%. And that 3fps could even be by lowering FSB from 400>333mhz and not cpu clock itself. There must be some part in emulator that is blocking throughput by inefficiently transfering data, IMO. My gpu is also limiting but I still thing in major its emu, pcsx2 is up to 1024x1024 ok for me most of time. Then again, that one is using directX10 not some opengl crap.
