I'm reaching my breaking point. From the day I bought this game, I've had nothing but problems with it. I had to deal with that crashing during the first mission after the prologue except in my case, my xbox overheats without actually being hot. After the first few updates, I started managing up to, and sometimes a little over, a hour before the overheating, which I could tolerate. But now the problem has returned and I'm lucky if I get half an hour. It's not crashing, otherwise I would try the suggestions in the sticky post. I'm getting the two red rings and it happens even with good ventilation, no dust on the console, and only having been on for a few minutes. I turn it on, go straight into GTA V, and I get the problem without fail.
I love this game. I enjoy the customization, the cars, the clothes, but what's the point if I can't get anything out of it? I bought a new and bigger hard drive just for this game and somehow managed to finish the story, but if I can't resolve this I might as well sell it to contribute to something else.
