Textures are extremely blurry no matter what settings we try on my partners computer, to the point where nothing can be read and things like the shirts of the characters just look like a blob.

We've tried forcing the settings in a variety of ways, but the texture resolution just won't go up.

The video card is only a GTX970, but we should be able to turn other settings down so the game still runs well enough, while also being able to see the games textures.

I'm also having this issue. A sort of half fix that has helped some people has been to change the AMD FSR ratings to something other than "Off". However, I'm only having luck when it's set to "Balanced" or "Performance" which makes the rest of the game look very low quality. I hope this helps and I hope they fix the issue soon.
