this texture pack should be avoided. it offers no visual upgrade at all and adds heightmaps to textures which is only useful if you are using an ENB. the modding conmunity has infinitly better options that use alot less space and in some cases improves perfromance. if you wan an actual upgrade download the fallout HD (2k 4k is not for this engine). it replaces all base game textures with way better looking and optimize textures.
