It's certainly possible that the server is telling it to render dynamic objects at a shorter distance (reduced awareness), and that the client is screwing up when in that mode. That's what a lot of people are saying is happening, and it may be. I'm a bit confused as to why that wasn't the case for me, though. My missing textures were happening at off hours without any reduced awareness at all. And once I got the latest driver and it went away, I still wasn't in "reduced awareness" (although I did try playing during peak hours to try and trigger it).
