Lighting software developer ‘Geomerics’ has been working toying with PS4 dev kit. Apparently, they were very impressed by the PS4 performance. They believe the PS4 is capable of something called “full real-time global illumination technology”, which was implanted on the PS3 but they were forced to make some “compromises”
“We are delighted to be working on PlayStation®4. The hardware is everything we were hoping for in a next generation console, and a huge step forward from the current generation. Real-time global illumination was a big deal for games running on the current generation of hardware, but it required developers to make some compromises.”
They also affirmed that the PS4 won’t have any problem with the new Enlighten engine. The PS4 developers will be able to make developers create “far deeper levels of dynamism and quality to game lighting.”
