So I recently bought The Walking Dead game (by Telltale) for the Xbox 360 from Gamestop. I had been looking forward to it very strongly. (It is not the GOTY Edition, just the regular disc.) I started playing, and it had terrible frame rate. It was extremely laggy, and the cutscenes AND gameplay were lag hell. Every one or two seconds, the screen would jitter. On the action and combat scenes, it would freeze for around twenty seconds, while the audio would continue. I died many times in combat because the screen froze or lagged. The less action-oriented segments were a bit better, but they still lagged profusely. However, I trudged through the first episode, and thoroughly enjoyed it. But I'm not exactly looking forward to playing again because of the frame rate and lag issue. The lagginess didn't come and go-- it was constant the entire time. Not a second was safe from it.
I'm not sure if it is my copy of the game, because I've never heard of this happening on anyone elses'. None of my other games have ever done this. I have an older Xbox 360 from around 2009.
Should I trade in my copy for another? Will it change anything? Or does it have anything to do with the copy? Does it have something to do with my Xbox handling it? What can I do to fix this problem? Has this happened to anyone else? Please help! I REALLY want to continue this game, but it is a tedious burden to do it with this constant and profuse lag and frame rate issue. Thanks!
P.S. I don't have Xbox Live.
