It's sad to see that the lowres texture didn't get any kind of an improvement from PS3 to PS4 and as I'm so damn lazy (and not skillfull with Photoshop), I upscaled every Texture to x 2 using Waifu 2x. For the curious who doesn't know what Waifu is, here a quick explanation: Click me ^_^

Update:
I've redone all texture files except FFX-2 with a superior Algorithm and Models using ESRGAN. The models used retained most details and added some in the upres process where Waifu would normally kill fine details like leather (see new comparison shots on the Nexus page. I've also added a mirror from google drive).

I'll only update Nexus going forward.
