I had a similar problem with a PC game and it turned out to be the TV. It wasn't handling 1080p as it should.
I thought it was my graphics card but when I moved the PC upstairs and used a monitor it worked fine. Save me money because I was about to dump the card.
1080p movies worked fine on the TV but the game was the problem. Other games also worked fine. Maybe the refresh rate set for the game was to high for it. I don't really know.
If possible try it with a PC monitor.
Probably not much help, Sorry. That's all I can offer.
