Halo 4 (and only halo 4) is having fps slowdowns that happen around a hour after playing usually after a firefight however not all the time. I have a feeling it's due to overheating because of this. I have cleaned the disk and the disk is in perfect condition
(not even 1 scratch). I have also rested my console cache and tried reinstalling multiplayer. The main thing I have noticed is that this only started after the frist update.
