This mod enhances the textures environment around you and that of some animals and creatures, making The Witcher 3 feel even more real. Depending on your set up, you might already be playing on ultra high settings and getting the best out of The Witcher 3. It goes as far as installing any updates to the mods you use and makes the whole process a bit less daunting. The easiest way to install mods would be to use the Nexus Mods Manager. Let me be the first to congratulate you on choosing the correct game to mod. There are mods that allow you to fast travel from any point on the map, ones that show every single object if you like to really test your eyesight, and mods that make The Witcher 3 a bit of a gore fest. Mods can do weird and wonderful things to games, as well as make enhancements to combat, environmental textures and other things that the community thought was lacking.
