I have been following this thread extremely closely with a watchful eye for about a year ever since I caught the problem, I have finally made an account to report my experience.
I get a massively low level of detail in nearly all games and suffer from massive pop in from close range distances in all games and it seemed to have happened about 3 months after upgrading from 1060 6GB to 2070 RTX with a 600W EVGA WHITE PSU. I always had the same PSU, but had 2 sudden shutdowns while playing in that time with the 2070 and they were only when playing the RE2 timed demo. There are many people with different issues, some have bad shimmering/AA (me personally not at all) whereas others like me have very bad LOD/Level of Detail quality and all of a sudden, grass and shit in close proximity is popping up everywhere, which is what my system suffers massively from pop in, from everywhere, even in very close distance, whether its trees when you zoom in on them or shadows that flicker when you move beyond a certain point. I don't know why but Insurgency Sandstorm is more playable on my friends 4460 i5 1060 3GB compared to my 4790K 2070 8GB and it's freaking me the fuck out. The only thing that stands out from a while back (say when I noticed things) my system hard locking and shutting down when I played the Resident Evil 2 demo on Steam. It crashed my PC a number of times and from what I can recall that is when the issues started to occur. It could have well been an unstable CPU OC however but it wouldn't have been a crazy one as my CPU doesn't allow it. (4790K)
I am thinking about returning my 2070 while I still can because it seems to me like a GPU fault/VRAM fault/Micron Memory fault.
What would help is if everybody could report their specific issue and their specs in the same post, like so:
