The 15,000 count includes 13,000 upscaled textures from the base game, plus 2,000 textures from DLCs.
Moreover, it is made using Gigapixel AI, Waifu2x, ESRGAN, ImageMagick, Open Object REXX scripts and GIMP 2. However, this one is improves the quality of 15,000 textures. Sure there are other texture enhancements out there for the aging game. A new set of textures has been released by modder DcCharge on NexusMods ( via DSOGaming). Great news for Fallout fans who are still playing New Vegas after all these years.
