Author killerkoalas has created a complete set of AI-upscaled textures for NWN2, significantly enhancing the look of the game.

It would be interesting to try it with other NWN2 enhancement mods, such as Kaedrin's 'PRC pack', Tony_K's 'Companion and Monster AI 2.5', Reeron and Trekari's Spell 'Fixes and Improvements', and Tchos' 'HD UI panels and dialogue compilation and expansion'.
Neverwinter Nights 2 2022 HD Texture Pack
A complete improvement of nearly all textures in the vanilla game using both ESRGAN upscaling and manual editing.
As of version 1, only AI upscaling has been done. Every texture except for trees and VFX has been upscaled to either 2X or 4X their original size.
There are two versions - recommended and full resolution. The recommended versions contain 2x vanilla resolution textures, while the full resolution versions are 4x. Beware that using too many of the full resolution packs may cause stability and performance issues.
