    Sounds right. But then that means Nvidias driver gets the PS 1.4 shaders and "recompiles" them to multi-pass PS 1.1 shaders?
    Here's the relevant quote from http://www.extremetech.com/article2/0,3973,888228,00.asp :

    Are DX9 CAPS reported by drivers at some "init time" and cached by DirectX API layer later? By init time I assume first time any application initialized DX9 interfaces.

    Just FYI, the R9100 is the same as the 8500.

    1) Yes any DX9 card would benefit from it, or that is the theory at any rate. Since GFFX and Radeon 9500/9700 series are the only known cards manufactured at this time to be DX9 they would both support PS1.4 via PS2.0

    2) Already answered and again in theory it will use PS1.4 in the PS1.4 capable tests.

    Whether the GFFX utilises PS1.4 or not is not something anyone has looked at in enough detail yet and it is a shame in the forthcoming Preview at B3D we will have to wait longer for an answer. I will say though that I expected the GFFX to be utilising PS1.4 in the relevant tests.
    It has been tested with tb's ShaderMark that the GFFX is capable of PS1.4.
