Epic Games will be demonstrating desktop PC game content developed with Unreal Engine 4 using NVIDIA’s next-generation mobile processor, “Project Logan” during SIGGRAPH 2013 which runs through July 25 in Anaheim.

Epic showed a demonstration running OpenGL 4.3, and Project Logan features the same Kepler GPU architecture powering NVIDIA’s GeForce GTX 680, 780 and Titan video cards.

The firm has shown its Samaritan, Elemental and Infiltrator demos on NVIDIA Kepler-based GPUs before, but now it can run the same GPU architecture in a mobile chip.

“This bridges the gap between highly desirable PC game experiences and what we are already achieving on mobile devices with Unreal Engine 4 and Logan,” said Epic Games. “Mobile games soon will be built using the same architecture as PC games, following the latest standards, and using the most powerful, scalable tools.

“We think the next generation of games will be the most incredible one yet, and we’re just getting started.Today marks a new technological milestone in Unreal Engine history.”

Epic’s senior graphics programmer Brian Karis showed the firm’s Unreal Engine 4 Infiltrator demonstration at SIGGRAPH’s annual Real-Time Live! showcase on Tuesday.

“The big news here is NVIDIA’s support for the OpenGL 4.3 feature set, which brings to mobile devices the same high-end graphics hardware capabilities exposed via DirectX 11 on PC games and on next-generation consoles,” said Epic CEO Tim Sweeney. “And this isn’t your father’s GPU: NVIDIA’s mobile graphics technology is built on the same Kepler graphics architecture found in its latest generation of PC GPUs.

“It’s the same Kepler architecture on top of which we’ve created high-end Unreal Engine 4 PC demos, which have taken advantage of over 2.5 teraflops of computing performance. More than ever before, we see the opportunity for developers to create high-end games and ship them across multiple platforms on a wide variety of devices, including tablet, smartphone, Windows, Mac, PlayStation 4 and Xbox One.

“It’s all running on a chip no bigger than a fingernail, and is just a taste of what mobile Kepler will make possible.”

Below, you will find a the “Ira” tech demo posted by NVIDIA featuring real-time modeling of a human face powered by Project Logan using a 250W+ GeForce GTX Titan graphics card. It was also running on a reference tablet drawing 2-3 watts.
