So i have been having a problem with my bo2 disc because whenever i get into a game i used to be able to go about 5-7 games without freezing then it got worse to the point right when i join a game i freeze and have to do a hard reset. My disc is in good condition and there are no visible scratches and i clean it often and i have also done a system rebuild and restored the file system multiple times. Basically ive tried all the troubleshooting options and it still doesnt work. Ive been reading alot and people are saying its my disc reader so i was thinking should i get the digital version so it doesnt freeze anymore, i heard its better anyways, also will my dlc still be there even though i went to digital because i have all of the map packs. If anyone can help me out it would be much appreciated.
Does the freezing also happen on local play or zombies? Also, have you tried it without internet connection? Limited connectivity to the game also causes some freezing. Also, I would suggest you try to delete your game data utility for black Ops 2. It should be in the game section from the main menu of your PS3.
You can also try using other account and see if you have the same problem. Cleaning the disc might help you too.
Try installing textures as well. Go to Multiplayer then to Options and select Install.
This usually helps in freezing issues.
You can also try the disc on another console and check if the same thing happens.
