Looking at the game I think the PC version uses the same textures as the Xbox One or PS4. They look of low quality even blurry. I tried no DLSS and then the on settings. Looks almost the same on all the settings except for performance+. Playing on a 4k 43" TV but at 1440p on a nvidia 2080. Wish I could grab another gpu but there is like none in sight. Even with a new gpu I don't think it would do anything for textures.
This is by no stretch of the imagination correct. This game looks a million times better on PC than it does on Console.
