Infiltrator: GTX 680-Powered Unreal Engine 4 Tech Demo Unveiled

Featured Stories

Each year, game developers assemble in San Francisco for the GDC Game Developers Conference, where programmers, artists, producers, game designers, audio professionals, business decision-makers and others involved in the development of interactive games gather to exchange ideas and shape the future of the industry.

At GDC 2011, Epic Games stunned the crowd with the Unreal Engine 3 “Samaritan” demo, which offered industry members their first look at the next generation of videogame graphics. Running on three GeForce GTX 580s, the Samaritan demo introduced the world to dynamic facial tessellation, point light reflections, bokeh depth of field, subsurface scattering, and several other highly advanced techniques.

Learn more about the Samaritan demo in our exclusive deep-dive that includes commentary and quotes from Epic Games’ tech genius, Tim Sweeney.

At GDC 2012, Epic showed attendees an optimized version of the same demo, running in real-time on a single next-generation NVIDIA graphics card, later revealed to be the GeForce GTX 680. Behind closed doors was where the real magic was happening, however, with the unveiling of the long-awaited Unreal Engine 4. Publicly announced three months later, Epic’s Unreal Engine 4 “Elemental” demo was as groundbreaking as the previous year’s Samaritan demo, primarily through the introduction of next-generation real-time Global Illumination lighting.

For those interested in the technology behind Infiltrator's impressive demonstration, here’s a brief overview of the features on show:

  • New material layering system, which provides unprecedented detail on characters and objects
  • Dynamically lit particles, which can emit and receive light
  • High-quality temporal anti-aliasing, eliminating jagged edges and temporal aliasing
  • Thousands of dynamic lights with tiled deferred shading
  • Adaptive detail levels with artist-programmable tessellation and displacement
  • Millions of particles colliding with the environment using GPU simulation
  • Realistic destructibles, such as walls and floors
  • Physically based materials, lighting and shading
  • Full-scene High Dynamic Range reflections with support for varying glossiness
  • Illuminating Engineering Society (IES) profiles for realistic lighting distributions

As we speed towards the next-generation of Unreal Engine 4 games, you’ll be sure to hear more about the technology powering these breathtaking scenes here on For now, enjoy the demo and rest easy in the knowledge that PCs continue to be at the cutting-edge of videogame graphics.
