64Bit machines have been around since 2007. I'm not sure why anyone would have purchased a 32 bit machine, like holding on to XP long after Windows 7 had been going for several years and now Windows 10. I'm not sure why EA allowed them to go back and grab old integrated graphics and very old Intel chips or Nvidia chips that were extremely old cards even when people were playing TS3. It's always made me wonder why TS4's requirements included very old cards, systems and chips even before TS3 was even produced.
