We're entering a world of mainstream 64-bit computing -- whether we like it or not. Just weeks after Adobe started requiring 64-bit Macs for CS6, DICE's Rendering Architect Johan Andersson has warned that some of his company's 2013 games using the Frostbite engine will need the extra bits as a matter of course. In other words, it won't matter if you have a quad Core i7 gaming PC of death should the software be inadequate; if you're still running a 32-bit copy of Windows 7 come the new year, you won't be playing. The developer points to memory as the main culprit, as going 64-bit guarantees full access to 4GB or more of RAM as well as better virtual addressing. Andersson sees it as a prime opportunity to upgrade to Windows 8, although 64-bit Vista and 7 (and presumably OS X, if and when Mac versions exist) will be dandy. Just be prepared to upgrade that Windows XP PC a lot sooner than Microsoft's 2014 support cutoff if you're planning to run the next Battlefield or Mirror's Edge.
