You need to download the premade conflict resolution patch - which also means installing all the stated mods - or many things wont work right. You need iPresentInterval = 1 (or missing) in skyrim.ini(its put in skyrimprefs.ini by the game, where it does nothing), EnableVSync=true in the enblocal, and if you have a screen with a refresh rate higher than 60 probably an fps limiter, unless you're willing to run in fullscreen or limit your desktop fps to 60. I'm using the NVidia one, set to 58 as per STEP guidelines, because I have a 120hz screen and hit 90fps indoors otherwise - which can lead to issues.
