Well I finally solved the problem with the game only stuttering in full screen mode by locking the in game refresh rate to 60Hz in catalyst control centre. It seems that although my desktop refresh rate was set to 60, the game was switching to a different frequency when launched, hence why it was fine in windowed mode.
The only problem I have now are these horizontal tearing lines which are pretty shocking in all honesty. I've tried playing about with the vertical synch settings etc but nothing seems to improve it.
