Over the past few days I've been having this graphical glitch.
What happens is that different parts of the environment will change into different colours (red, white, blue, yellow etc) and each colour has is made up of a small squares. I wont happen to the entire screen, only portions of it intermittently. I can look at it and it will be there and when I look away and look at it again it disappears. It also does the same to my weapon camo and the smoke trail when throwing a grenade.
It also effects the sound. In the game lobby the music will play fine, but once in a game the sound will also mute and the only thing I can hear is party chat and enemies gunfire. I cannot hear announcements, when I reload, footsteps, ceth gunship, explosions, my own gunfire... nothing at all except the aforementioned.
It's becoming more frequent and I think it also effects hit detections also as I have found that I will be putting rounds and rounds into people while this is occuring and barely kill them when usually this doesn't happen without the glitch.
This is really annoying because on top of everything else this literally makes the game unplayable. If I cannot hear anything and the screen keeps getting messed up then I can't play it deaf and partially blind.
