For sake of time at the moment I will keep things simple. I am on a laptop and Zombies wont load when I try to play online. I've made a lot of changes to get it to work but it still hasn't. Multiplayer works perfectly(no lag, loading time is fast, in game is smooth). Solo Zombies works perfectly( same as Mp). I'm not sure if Zombies is just to large to run( I would think that if I am able to play multiplayer online and it works so well that Zombies would be able to load too) I've updated drivers as far as I'm aware so If you have any other suggests or had similar problems with solutions Please, please let me know. Thank you.
