It's not an extended play issue for me. I have this issue and it starts in under 5 minutes so for me to be able to actually play the game without the worst stuttering I have ever seen I would have to restart about every 2-5 minutes. I haven't touched the game since october 26. after playing it for 2 days and suffering through the worst stuttering in the history of mankind i had enough and didnt even touch any end game stuff. as soon as the campaign ended I left the game and haven't touched it since and wont ever again until it gets fixed. If they do fix the stuttering, which I have little to no hope of them doing, by then it will most likely be too late as after having the games shelved for going on 6 days now I am not even excited about ever playing it again because the experience is already ruined. I would demand a refund but i bought it through greenmangaming. not like blizzard would give me a refund anyway after playing it for like ten hours and beating the campaign. worst purchase of the year for me, huge waste of $53 for something I can't even play, bungie has no support email, won't respond to my posts, and give us a cryptic message like "we are aware that there are 'hitches' (they refuse to say 'choppiness' or 'stuttering' or 'we completely f-cked up') after 'extended periods of play' " (they again refuse to acknowledge that it's as bad as happening withing a few minutes because that would look really bad for them to admit how horribly they fked the game for a lot of ppl on launch). It's like they are night thieves with no way of ever finding them and getting any answers. They steal your money and give you an empty box in return then if you are lucky enough to ever catch one and tell them your problem they move very, very, very slowly in the night back to their den to "fix" the problem. but since they are night thieves your chance of ever seeing that box back with a working game in it is about a 12% chance. If they fix this problem. Not lessen it, or try to make it "more tolerable", but completely wipe it out and make the game run smooth which is the main reason I own a pc worth over $2500 is to play FPS game smoothly and with a mouse and keyboard, and if they fix it soon enough, I would even throw some money their way in support on their in-game loot things. But for that to happen it needs be completely fixed and fixed soon.
