I want to ask what is causing the phenomenon, I noticed during the game that a strange aura-like thing appears while moving the camera
I don't really see what you're talking about. Maybe I'm just blind?
Perhaps it's just the motion blur option if there is one? Also just make sure your gpu drivers are up to date. These are my best guesses
I've been trying to turn off motion blur I've tried several video card drivers on other monitors and the same strange pixel aura around the characters
I couldn't see anything either. I have in the past experienced that before, I think it has to do with anti-aliasing.
