I saw two demos running on the new prototype.
The first demo was running in real-time 2160P @ 60FPS with a new AA system developed by the engineering team of 343i, the delivery system better results over the TXAA 2X with free performance over 64MB of SRAM new system.
It has been said that the prototype has dedicated physical processors, particles, audio, upscaling, and a new chip that works in color / HDR in order to improve the final quality of the images.
Textures and shadows in HLSL 6.0 and a new version of TILED RESOURCES are superb.
The second demo was running in real time 2160 @ 60FPS developed by DICE, the latest version of Frostbite. I think it's part of a new RPG, it is absurd. The forest, vegetation, water, textures, lighting and shadows, it seems some video of Graphine, seems reality, it looks like a movie.
The system is still in development and has huge margins for optimizations and improvements until the launch next year. Panos Panay is under the creative control. I saw some of the designs, and all of then is amazing. They are testing new liquid cooling system more efficient in order to have better margins optimizations and increased clock.
