Bad news for those still running 32-bit operating systems; a tweet from DICE Frostbite rendering architect, Johan Andersson states that you'll need a 64-bit OS to run next year's games powered by the Frostbite 2 engine.
If you are on 32-bit, great opportunity to upgrade to Windows 8" Johan Andersson, DICE
We have already seen Battlefield and Need For Speed: The Run utilising the new engine, and next year's Medal of Honor; Warfighter will be running the tech once again. It seems between Frostbite 2 and the upcoming Unreal Engine 4, we're in for some graphical treats next year.
