Why was Additional Hardware removed from the control settings? Upon installing Loki I had very bad stuttering and lag playing video, then I reinstalled Additional Hardware and the Nvidia Drivers were listed there, along with an Intel CPU microde driver, I installed them both and stutter is now gone system is running great. Please add back this feature, it is system critical, I know some users my finding it daunting, perhaps adding a warning message that altering drivers is for advanced users, but I find this feature critical.
