Modern Warfare Stuttering

Hey guys I recently bought a new computer I bought Call of Duty : Modern Warfare and it runs perfectly everything on ULTRA but I have this weird stuttering with 3 orange boxes on the left now I know this refers to packet loss but I have 0 packet loss I enabled it in game

My Specs :
