This is for people experiencing the partially invisible Khajiit, the erratic disappearance and reappearance of details, overall patchy specklyness (not the black spots of doom), etc.
You will know if you have this problem most of all if when the guy says "stay close to the wall !!!!" and the dragon comes down, it's wing flickers with transparency.
Turn off all antialiasing, then in 'advanced' tick the box that says FXAA.
For me it not only solved the glitches, it also gave an overall MAJOR performance boost.
