If your gaming PC still, somehow, has a 32-bit processor and operating system, you really might want to start thinking about upgrading. More than you should've been doing these past eight years, anyway. Battlefield developer DICE has revealed that by next year, there will be games built upon its Frostbite engine which require a 64-bit OS.
DICE rendering architect Johan Andersson revealed this nugget on Twitter, noting "If you are on 32-bit, great opportunity to upgrade to Windows 8." Or Windows 7. W7 is good. Get that.
As well as serving as the foundation for DICE's own games, Frostbite has also been used by other EA studios for Need for Speed: The Run and Medal of Honor: Warfighter. The only 2013 release so far confirmed to use Frostbite is Command & Conquer: Generals 2, so that's one possible candidate.
Now, honestly, get with the program and upgrade to 64-bit. Steam's ongoing hardware survey shows at least 20% of the digital distribution platform's users are still on 32-bit versions of Windows, so buck your ideas up. We were all promised a 64-bit gaming revolution back in 2004, and you holdouts are ruining it for the lot of us.
