So, with crossfire enabled with AFR (alternate frame rendering) I get up to 30-40% increased FPS depending on the situation. However, whenever I kill someone, my FPS gets halved due to the pop-up on the screen. I mean, from 80ish FPS for example, I basically go down to 40. It is not related to shooting, or any other thing, it is directly related to the kill pop-ups I get. What's the deal with this?
