Windows 7 upgrade = poor Dolphin performance

[Shonumi]

OCing your CPU should almost never result in a slowdown with Dolphin, aside from cases where the increased temps lead to automatic throttling. GPU OCing shouldn't cause slowdowns either, for the most part. The only thing I can think of that might be a concern would be any power-saving options enabled from your GPU drivers, but that's pretty unlikely to be the source of your issue
