To those who still can't get 60fps with overlocking: turn off governor. and with a docked stable 55+ fps in main area, you need 2000+ Mhz CPU and 1300+ Mhz GPU.
Sure, if you really want/"need" the highest quality there is you can grab remuxes. But will be pretty big file sizes, so disks can be better in that regard.
But piracy is free so...
some bluray rips are kinda crappy, remuxes are a more safe bet, but i usually don't have trouble finding a good rip, there are certain groups to avoid and some to look out for
