Clouds agian

Just wondering I have active sky 6 but is the DXT clouds in that better on visuals and framerate than default or is there another set I should use. Just trying to squeeze every ounce of performance But for somereason the clouds tend to (glow in the dark there super bright in the middle of the night and that looks fake as no other) I know search lol But at work I cant use search for some reason and I would like to try something when I get home.
