Can somebody confirm this isn't happening to me only. Not sure if it was like this before the patch or not but I have been noticing when the weather is foggy, the npc's are a bit pixelated. Also when looking down the scope in foggy conditions its pixelated. If I move the camera where this is no fog, it goes away. I have read that the PC version suffered from something like this also.

Yes happens to me, I also get occasional graphical artifacts ( mostly on light sources) ocassionally in foggy areas and ps4 fan speed increases very much. Most of the time these occur after the game has been on for over 2 hours or so, exiting and restarting the game resolves the issues for me. No similar issues in other games so the ps4 is not at fault and is not overheating.
