[GeForce.com] Epic talks Samaritan & future of graphics

post #1 of 5
Thread Starter

At this year’s Game Developers Conference, attendees were wowed by Epic Games’ Samaritan presentation, a sneak peak at the visual fidelity achievable with Unreal Engine 3 and the horsepower of three NVIDIA GeForce GTX 580 graphics cards. Offering a world first look at a real-time demonstration constructed entirely in DirectX 11, Epic’s Samaritan demo set tongues wagging, and served as a wake-up call for those in the industry still languishing in the dark ages of DirectX 9.

The technology for the Samaritan demo took eight months in itself to develop and implement, work having first begun in June 2010, when NVIDIA Developer Technology Engineer Bryan Dudash and his team initiated development of Epic’s Unreal Engine 3 DirectX 11 RHI graphics wrapper code, which in layman’s terms allows the Unreal Engine to output anything that utilises the advanced features of DirectX 11. Epic’s engine team pre-planned and implemented the DirectX 11 features, and then commenced development of the actual Samaritan demonstration, which had been storyboarded and meticulously prepared in advance. "For the final stages of the demo’s development, NVIDIA engineers performed performance analysis and debug to make sure that the demo made the most efficient use of the GPU power available," adds Dudash, with work continuing apace on all sides, right up until the unveiling of the Samaritan demo on March 2nd, 2011.

In all likelihood, a game of equal fidelity won’t be a reality until the next generation of graphics cards, but in a chicken and the egg situation, how can hardware be developed for the next generation of graphical technology when it has yet to be programmed? For Samaritan, SLI allowed to everyone to bypass this dilemma, utilising the raw power of the three graphics cards with an ample helping of brute force. For NVIDIA, the collaboration with Epic was "the definition of a win-win," as Dudash puts it. "Working with Epic was an amazing experience. Their engineers are at the forefront of graphics knowledge in the industry and they have some of the top artist talent out there."

A very nice in depth article about Epic's Samaritan demo and the technology behind it. (with some nvidia marketing talk perhaps but all in all a nice read still) I also hope it hasn't been posted. I searched but didn't find anything.

Steps for success:
1. Make epic engine
2. Strip it for consoles
3. $$$
