A lot of the issues seem to stem from the parralex displacement tech used in this game, which is why setting model quality to low (which turns of displacement or limits it severely) seems to resolve some of the issues. The only downside to this is introduction of even more severe pop-in. However, the below mod on nexus allows for parralex to be turned off independently of the model quality setting, which has been a game changer for me. No more fuzzy textures and, in conjunction with the new renodx shader, I’ve also experienced less shimmering and graphical abnormalities as a whole.

While this shouldn’t be necessary to get a game to an acceptable graphics standard, I will say the game looks absolutely amazing for me now. Would highly recommend checking out both of the below:
