How fast does your PC have to be to run TP w/o the hyrule speedhack?

[Xtreme2damax]

I used to have much better speed w/o the speed hack on my overclocked first gen i7 920. With the DX9 backend a while back I was getting 22FPS - 25FPS late in the game, OGL was always slow. Now both OGL and DX11 are slow barely managing around 10FPS - 12FPS give or take a few fps.

Unrelated, my performance in Dolphin as of recent seems to have decreased. Not sure if any recent builds killed performance.
