Games will feature limited photorealism five years from now, claims AMD’s chief gaming scientist.

In a newly published feature on the future of graphics, AMD’s Richard Huddy, a veteran of the semiconductor and GPU business, said stills or short pre-rendered scenes may look real enough to trick observers.

He said a number of barriers remain for full photorealism however, such as screen size, as a screen would need to be 8k-by-6k to offer the 48 million pixels to match eye resolution. There are also a host of other technological hurdles to jump.

“The amount of processing time that is spent on very high quality shadows these days can, surprisingly, be quite a bit more than the amount of processing time spent on the rest of the scene,” said Huddy.

“That doesn’t feel terribly likely, but it’s awfully difficult to build stable, high quality shadows; there’s just no terribly good algorithm for that, and it’s a current barrier to photorealism.”
