The Witcher 3 HD Reworked Project
So this mod aims to please PC graphics enthusiasts, as the authors have reworked the game’s textures and models to create better looking ones that take advantage of modern PC hardware. This includes in-game objects like stools, buckets and rocks, but also other things like the vegetation have been given a makeover too. And this has been achieved without a noticeable loss of performance according to the authors, which is stunning indeed and surely highlights the amount of work that went into crafting this mod.
