(you were faster than in editing the kext)
i don't have any hitch in 3d or at least i don't understand what hitch you talk about can you please explain more(post a video)
No my first time editing kext

The thing is that when I launch Unigine Valley, I get weird 3D or none. Chess is working and autocad is launching ok
Streaming video is ok, divx as well, Cinebench is working as well.
Im gonna deactivate the intel GPU to see if that helps and try GraphicsEnabler=No,
i don't see anything until OSX is ready to be used but that's normal I haven't tweaked everything yet.
Maybe it is only UNIGINE that's behaving weirdly trying other 3D apps
