FPS - AntiAliasing

Massive FPS drop due to new graphics engine (assuming new since it now has antialiasing).

See attached Screen Shots. FPS goes from 67 in 13w37b to 6 in 13w38a. And actually make my client unplayable... Will revert back to 13w37b until I can get to my good PC and see if the issue is still present.

Unfortunately turning Antialiasing, Mipmaping, and Post Processing off, does not fix this issue

NOTE: I'm sure this is a duplicate by now of something but due to it being the new engine I figured it may stay on its own.
