Hello, this texture pack will *properly* upscale Dust2's 512x512 textures to 2048x2048 (4x) using Cupscale/ESRGAN; as an additional bonus, new Phong has been applied to many models throughout the map (more info is available in the Readme file that comes with the download), have fun :)
the first stable release, all info (incl. Installation and other stuff) is already included in the Readme file that comes with the download; enjoy :)
