The Mecha HK-2207 real-time demo features a number of post processing effects (depth-of-field, lens flare, ghosting, aerial perspective/atmospheric, LUT, emissive and reflection) provided as an easy approach for developers and artists to adopt Microsoft DirectX 11 programming. This demo also uses a current trend in game engines utilizing deferred lighting and deferred shading allowing many more lights and rapid prototyping.
NGOHQ also published NVIDIA's funny response:
Nvidia's Igor Stanek, Senior Product PR Manager of EMEA has posted the following response on his Twitter page: "Just tested Mecha Rampage demo and I'm very disappointed. It should be DX11 tech demo, but it looks like DX8/9 with 10 years old physics. Looks like NVIDIA is last company with real tech demos. Supersonic Sled, Aliens vs Triangles or Endless City are from different galaxy."There's a video on YouTube of AMD's Mecha HK-2207 demo and Stanek is right, this is far from a great demo to show off the capabilities of a high-end graphics card.
