I have installed the latest version and am a bit dissapointed in some areas. Interiors now look great but exterior areas suffer from very "unnatural" lighting. Doorways close to fires become a very dark red, armor becomes too colorful and snow becomes to white, which seems to "fight" against the more subdued colors of the rest of the game.
There is a HDR only version on Skyrimnexus which seems to be a bit better. It enhances the sharpness and HDR of the game only without changing colors etc like the pallete versions do.
