I have skyrim with realvision enb, at 1600p, but only have 1.28G of vram to use. I run my game without the HD textures, and I allso keep Anti aliasing and anisotropic setting low or off. What else can I do to lower vram usage? I am asking abeacue I am only using ~80% of my graphics cards but some times I get fps dips that cause a stutter. and I am running a i5-2500k@4.7Ghz, so I don't think it is a cpu bottle neck.
