As can be seen in the video ,

In a four minute video, NVIDIA shows what "Kal-El" – Quadcore has to offer.The demo is about "dynamic lightning" which is a big point in this movie. Indeed, it looks very good."Kal-El" should have a five times higher perfomance than the Tegra 2 Dualcore.the game isn't playable with a dual core. The power with the quad core makes the light effect run smoothly. The release date of this game should be in August.
