The Witcher 3 AI 4K Upscaled Project aims to upscale all of the game's textures. Earlier this week, the first release of the project has been made available online, and today some other textures have received the AI upscaling treatment.

The new release includes AI upscaled textures for the free DLC packs that have been released following the game's launch. These include the textures of the Wolf School gear set, horse items, additional costumes for NPCs and more.
