Hi Fred,
I'm having this issue too.
I can't say for sure, but I it happens only when i'm scoping or when I use a device in game (i.e. cloak, scan, blitz, etc). But it's not every time, generally happens 5-10 minutes after the match starts.
The game and the bios is up to date.
I'm downloading the lastest (04/10/2014) Hd Graphics Driver right now to see if it solves the problem.
