"The same rule applies to geometry instancing for ATI - It is mightily impressive that their hardware as far back as the Radeon 9500 supports this feature, and it's good to see ATI still supporting their older hardware by enabling features such as this and Temporal anti-aliasing, rather than keeping it just to their current high-end boards. However, the fact that this feature is only supported 'officially' as part of the Vertex Shader 3.0 specification, and thus needs a workaround in both drivers and the application to work on ATI cards could prove something of a difficult hurdle when it comes to having the feature enabled in games. It'll be most interesting to see what kind of success ATI have in pushing the adoption of this feature for their own hardware over the next year or so."
