Some textures up close (e.g. flat wall sections, parts of rock cliffs but also steel beams) look low resolution, while most looks super sharp. Since they are next to each other this looks quite jarring. Especially when cranking up to 5K or 8K.

Is this a bug or is it just the game?

(using a RX6700XT 12GB VRAM (no RBAR), game uses up to 10 gb vram, but „problem“ persist at 1080p low, remains clearly noticable at 1440p high)

It's just the game
