When AMD launched the Radeon HD 3800 series, they included some screenshots from their Ping Pong DirectX 10.1 Demo inside the HD 3800 series launch presentation, and in the DirectX 10.1 whitepaper. Now it’s seems that a Chinese website is offering that demo to the public. We have mirrored the file for your downloading pleasure. Anyway, in-order to run the Ping Pong demo you need a Radeon HD 3800 card, Windows Vista SP1 (?) and the latest DirectX Redistributable from March.
