The best spot in in the Options / Image / Debayer. Click the box that says "always record undebayered (RAW) but preview in color" (see image attached).
That way it shows all the pixels when I need them (to focus, set the crop box etc) but always turns them off before capturing so I capture at the fastest rate possible.
Also, make sure you use the RAM Buffer (in the System / General tab), set it to a high value.
Oh, and don't forget to set the USBTraffic value to around 70 to 80. Too high and it could drop frames, too low and the fps rate will drop.
Easy

If I haven't mentioned them before, watch these tutorial videos, they are great.
