Part of his reasoning was deconstructing the human eye, comparing it to a 30-megapixel camera. He went on to say that framerates becomes imperceptible to the human brain beyond 72 frames per second, and the highest resolution that can be detected is 8000x4000 pixels, just short of the recently revealed 7630x4320-pixel prototype television Sharp showed off at CES 2012.
To reach this level of graphic fidelity, however, computers will require graphic cards roughly 2,000 times the computational power of today's best graphics hardware. However, lifelike representations of lighting, subsurface scattering, skin, smoke, and fog will be available "in the next few years".
However, for lifelike graphics and AI to combine and present a truly lifelike experience, Sweeney feels that it is still several more generations away.
Still, “within our lifetimes, we will be able to push out enough computational power to simulate reality," Sweeney confidently informed the crowd.
