Well, in the last builds it seem that you get an enourmous increase of speed when disabling EFB-Copy. I read that it might give some speed, but as I tested it brings you up to 15 FPS in Hyrule field and the forest... can anyone confirm that? (you will have to enable the bleach vs. crusade hack as disabling the EFB-Copy will cause the ugly post-processing box in the upper part of the screen to turn into an ugly multicolor-box 
). With Watchdog to 15 the these two parts (hyrule field after kakariko) gets nearly playable
