I've since resolved the issue I was having, thanks for your help though.

I'm having this problem along with the screen image being wrong. It looks like I'm getting a blown up to fill full screen of just the top left of the actual screen, it's doing my head in as I can't proceed any further into the game. I'm using a 51" TV but I don't think it's my TV at fault as I have no problems on any other game I play.

Thanks dude, this worked a treat :)
I'm glad someone knows what they're doin lol

This doesn't work for me, I guess I'll have to wait for the game to be released properly

I've tried Alt + Tab and it doesn't exit the game for me, I've tried just about everything now.
I seem to be only getting the top left portion of the game screen but enlarged to full actual screen.

I'm also having this problem using a 51" HD TV, it's really frustrating not able to see any of the menu
and not able to click any option boxes, I've not even had chance to get in a game yet!
