1- For some reason, when looking through a scoped optic such as the PU scope or PSO-1 scope the game renders in a noticeably lesser resolution/looks much blurrier. I'm not sure if this is an AA issue or a rendering issue but it needs to be changed, spotting players is more difficult and the game looks terrible.

2- Awful blurry post processing on the back of guns that is clearly visible whilst looking down the iron sights of any gun in the game.
