Its has allot of textures mods installed I still have 3gb of vram that I'm not using I'm using 5 at the moment what I thought was werid that When I first got the card skyrim automaticly set it to high but I went to default and it went to urltra could there be something going on with the drivers I use to have a 660 and got this one but I never uninstalled nvidias drivers can that conflict it I should also note that I had to turn Vsync on in enb local or the fps will go over 60 and cause screen tearing and skyrim to go crazy when vsync is off I don't get no stutters I'm using the same enb as brodual use the Extreme performance project enb because I don't like a huge enb just something that looks nice I play on a Philips 40 in smart TV 60hZ can that cause it it stays at 60 just. Every now and then it stutters
I have a i7 4790k cpu
