Ghost fish are extremely grainy (+ other objects too)

The texture af the ghost fish is extremely grainy, the other fish and rest of my game is sharp

I’ve noticed some other objects’ quality is also grainy compared to the overall graphics quality, even though I play on Ultra settings.
These blinds for example, no matter which of the materials I use, it’s alwys grainy, not as bad as the fish, but still. This started after the August update and I’ve also seen players complain about this on discord (see below)

I often notice this with shadows, some are sharp like before the August update, but the shadows in the pics below are unacceptable for me
I though it was something wrong with my settings, but it’s the same no matter what I try and I’ve also seen this in others’ games. (other thread abt what I’ve tried is → here)
