This table is for version 1.33; look in this thread for a newer one. If I'm right it's version 4.
When I first launched the game, the textures looked perfect to me. As the time went on and I started unlocking facilities then the textures went blurry because of not enough memory in the GPU. It looks to me like as the game goes on it loads more assets and textures into the memory and it finally reaches a point where it just uses low resolution ones. Too bad you can't pick textures for the world and characters separately because that's what's most important in a game like this.
Since the new DLC came out my PC can't handle it even with the facilities down to level 0 so I just gave up at this point.
My PC is too potato for this game
Not all clothes load the same, some still look HD but you gotta look for them by yourself. For me it's only lingerie though.
If you're not sure whether what I said applies to you, you can test it yourself. Just backup your save and start a new game by deleting old. When you start the clothes and assets will look nice and sharp, but as the game goes on, you unlock facilities and Einomaru then it'll most likely become blurry.
