come on. you know i'm a programmer. and yes i do have dx9 installed, including sdk. how difficult is it to code up a simple bench wich rotates a sphere with millions of triangles?
its no 3dmark, but you can use it to compare speed.
same for simple dx9 demos..
and yes there where people doing it. john carmack is one. he used opengl, but the dx9 features he used anyways (ARB_fragment_program in this case). gfFX did not showed really much power..
the dx9 pixelshader 2.0 where rather slow on the gfFX compared to the radeon. dunno about the actual test-programs that ran, but well.. give me gfFX and i can test it myself.
for demos using dx9 features (as i said, ARB_fragment_program mainly in opengl that is), check for example http://esprit.campus.luth.se/~humus/
or http://www.area3d.net/nitrogl/
or others.
but no, there is no 3dmark2003 out, wich uses dx9. so no "gfFX has that much points, r300 has that much". but one thing's for sure. the gfFX does not have any amazing performance on dx9 as well.. the same as on the rest of the tests, more or less..(the dx8 tests that is)
