AMD Radeon HD 7900 Series Direct3D 11 Demo: Leo in Sneeze The Day

JeGX — Sat, 28 Jan 2012 14:16:27 +0000

AMD has released a Direct3D 11 tech-demo to showcase the performance of Radeon HD 7900 series. This tech-demo is based on a (home-made?) engine in version 3.3 (build 1). Seems AMD ditched the Trinigy engine used in the previous HK2207 tech-demo. This D3D11 demo uses Bullet for physics and Fmod for the sound. The Leo demo showcases a real-time, DirectX® 11 based lighting pipeline that … Continue reading AMD Radeon HD 7900 Series Direct3D 11 Demo: Leo in Sneeze The Day »

Low Level GPU Programming: the Future of Game Development on PC?

JeGX — Thu, 17 Mar 2011 09:29:18 +0000

Low level and API-free programming seems to be the future of game development and graphics programming on the PC. Do you know that graphic hardware on PC is limited to few thousand of draw calls per frame (around 2,000 to 3,000) while the number of draw calls on a console can be 10,000 up to 20,000? According to Richard Huddy (AMD’s head of GPU developer … Continue reading Low Level GPU Programming: the Future of Game Development on PC? »

Microsoft has updated the HLSL language of Direct3D with the support of symbolic differentiation or derivatives. Derivatives are specified with the ‘ operator, which was previously unused: float times = a*b; float Dtimes = times‘(a); \\partial with respect to a float DDtimes = times‘(a,a); \\second partial float DaDbtimes = times‘(a,b); \\partial a, partial b Derivatives arise frequently in graphics and scientific computation applications.

How to Hack and Speed Up Direct3D 11 Render Calls

JeGX — Fri, 06 Aug 2010 07:45:24 +0000

Humus has explained a cool hack that allows to speed up a bit the Direct3D 11 render calls. The ID3D11DeviceContext is an abstract class with pure virtual functions. The principle of the hack is to directly access to real function pointer avoiding indirections due to the virtual table. For example, here how we can accelerate the function ID3D11DeviceContext::DrawIndexed(). In the virtual table of the ID3D11DeviceContext … Continue reading How to Hack and Speed Up Direct3D 11 Render Calls »
