where did you find all the "preferred" specs, that you mentioned, and that microsoft supposedly gave? please direct me to some link on microsoft's site...i went through the dx9 docs and only came up with the minimum specs
btw, the 9700 supports 64 and 128bit float frame buffers IIRC and temp registers need to be fp24, not fp16, to meet dx9 specs
The preferred 32 bit is for texture input only. So I should have been more clear on that, "preferred" texture output is kinda irrelevent anyway,
And yes FP 16 does not meet DX 9.0 specs mainly due to the 24 bit texture cooridinates,
DX 9.0 used to (or still does) allow for partial 16 bit precision on floating point reads ect, But I'm not sure if the GeforceFX is doing that.
But that has nothing to do with texture output maps :P
