Hey matt. Can you post what settings did you enable to get rid of the lag in the developer options?

Check: Disable Hardware Overlays, Force GPU Rendering, Enable 4x MSAA
I also have all 3 of my animation scales set to .5x just to make the animations not take as long.
I use the standard screen lock instead of the Light or Ripple effect options, and I use Nova Launcher Prime.
All of this in conjunction quite literally gives me a truly lag free experience.
