He needs to tell his console to stop dropping frames. The first one he ordered didn't work at all, so he had to send it back. The second one worked for about a day. While playing it, its frame rate would steadily decrease until it froze altogether. Then it would give him some error upon reboot and stop functioning. The third did the same, but it took about a month. Now he is on his fourth. Although it still functions, its frame rate frequently drops and it freezes quite commonly (it freezes after about an hour of play nearly every time we play it). Similar issues have been experienced on all of the X1s my friends own. When I first heard about people having these issues, I thought they were exaggerating. Unfortunately they weren't.
