PC Prospective wrote:The Truth
There are few people in the gaming industry that you simply must pay attention to when they speak. One of them is John Carmack, founder of id Software and a friend of the site, creator of Doom. Another is Epic Games' Tim Sweeney, another pioneer in the field of computer graphics that brought us the magic of Unreal before bringing the rest of the gaming industry the Unreal Engine.
At DICE 2012, a trade show for game developers to demo their wares and learn from each other, Sweeney gave a talk on the future of computing hardware and its future. (You can see the source of my information and slides here at Gamespot.) Many pundits, media and even developers have brought up the idea that the next console generation that we know is coming will be the last - we will have reached the point in our computing capacity that gamers and designers will be comfortable with the quality and realism provided. Forever.

Surfing the web came to this article of commentary on Tim Sweeny's DICE talk and the talk itself. I have to say I found both fascinating because it goes mathematically into what we will need in GPU power to achieve photo-realism. Not as in Holodeck, but as in the ability to render a scene on a monitor at a speed at which details would be indistinguishable from real objects and fast and detailed enough our eyes could not detect any lag or shifting.
TL:DR Tm Sweeney is a terrible public speaker who spends half an hour explaining that we need roughly 2000% of today's CPU/GPU power to achieve that goal. Also he does maths.
