With the new gamma scripts to remove this overly dark shading of Witcher (no it does not get darker than a new moon`s night at 2 a.m. when it slightly starts to rain at high noon), supreme to extreme graphics settings mod to remove any graphics pop-in, and the newest "The Witcher 3 HD Reworked Project Ultimate-1021-12-0" mod, Phoenix ultimate mod with two cloud mods, the game looks absolute stunning and is almost beyond perfection!
Witcher 3 PC version was so many years ahead after release from a graphical point of view, that this kind of graphics quality will probably not even be possible with next-gen consoles.
Well there are some other mods running like various armor retextures, the usual Geralt mod I am always using since 2015, and some other goodies.
