Last year at GDC 2011, Epic Games unveiled their Unreal Engine 3 Samaritan demo in partnership with NVIDIA, giving gamers a preview of next-generation graphics. Pushing three GeForce GTX 580s operating in SLI to their limit, the demoed wowed all with a level of fidelity previously unseen in a real-time demonstration. At GDC 2012 Epic showed the Samaritan demo once more, but instead of three GTX 580s, the demo was powered by a single ‘Kepler’ graphics card, later revealed to be the GTX 680, our flagship GPU. Today, Epic has unveiled Unreal Engine 4, and it too operates flawlessly on a single GeForce GTX 680.
