There's always plenty of graphical enhancement mods for The Witcher 3, many focus on ENB presets or higher resolution textures to enhance what is, lets be honest, an already stunningly gorgeous game. Occasionally though one comes along like this which just has to be mentioned.
These are some of the most amazing skies I've seen in a video game, and it's all thanks to the New Heavy Clouds mod. You may not think clouds would make much of a difference within a game, but this mod really changes the whole atmosphere of the game, for the better.
The mod overhauls the cloud textures used in certain weather conditions, and as you can see from the video above, the results are amazing.
