Select all AMD and nvidia drivers and reboot.
Once you reboot re-install the latest stable (non beta) drivers. I believe the latest stable drivers are 295.73 http://www.geforce.com/Drivers
Firstly, thanks for the quick response!
I used Revo Uninstaller Pro to remove the AMD drivers, however I'll give it a once over with Driver Sweeper and see if that fixes it. Will install latest stable drivers after (used beta drivers because of an explicit SWTOR update note that I was referred to previously on SWTOR forums).
Thanks once more for the response! I'll try after work and see how it turns out and post my results.
