Want to know when DirectX 9.1 is out? you do then head this way to 3DCenter!
To make it clear right from the start, DirectX 9.1 will most likely never be released. But there is the persistent rumour that DirectX 9.1 will boost performance for Nvidia cards up to 60%. We will now analyse this rumour. First of all: Would this be possible? Clear answer: No. Though the pixelshader of the FX series has quite a lot more functionality than the hardware of the current Radeons, it is only capable of executing less operations per clock cycle. If the shader program was coded in a radeon-optimized format, the CineFX architecture will additionally be slowed down. The way instructions are coded in favour of the Radeons causes execution interruptions on Nvidia hardware. The Radeons are not so vulnerable, admittedly it's because of their simpler shader implementation.
