The PlayStation 4′s PC based hardware means it will be a lot easier to make games for the system. And it also means that game tool makers will have a much easier time bringing their tools to the PS4. Game engines, physics toolkits, etc. will be much easier to implement on the PlayStation 4 than they were on the PS3, which is always a great thing for developers.
Geometrics, a company that creates the highly popular Enlighten lighting technology used in games such as Battlefield 3, have announced that Enlighten will be available for the PlayStation 4 console. The lighting technology will be used in the upcoming Battlefield 4, which has been confirmed for the PlayStation 4.
