Graphical Bugs / Low LOD on PC

I am having a very annoying graphical glitch, where objects suchs as rocks trees, and sometimes shadows pop-in in the corners of my screen. I have provided a link to a video highlighting the issue. Does anyone have any ideas as to what may be causing it?

I have already tried DDU my drivers, and re-installing the latest ones.

Thanks in advance.
