While I like using AP Neural Enhanced Textures v3 as a base for my textures in DAO, I had to be honest with myself: It's way overkill. There are so many 4k and 8k(!) files that the game reliably crashes in multiple places, even on a quite beefy rig. So, I took this upscale mod, and used Ordenador to downsize them all the way down to 1k.
That's right. This is NOT some mindblowing super-mega-hyper-sexy texture pack. This is 1K textures with 1K normals. This is STILL larger than the base game, but it's about as high as I'm willing to go without causing more memory leaks for this poor 32-bit game.
