Age of Empire III
To test this game, we saved a scene with a movement of units.
Anisotropic filtering was activated via the game.
The Radeons were completely left behind with the "small" 6800 GS almost ahead of the X1800 XT. In addition, gains from the new architecture were reduced.
With antialiasing, the Radeons were back, but it wasn´t enough.
With HDR, the situation was identical. ATI was clearly behind. HDR produced a similar result for NVIDIA and ATI, but it wasn´t processed similarly, based on FP16 for NVIDIA and FX10 for ATI. If only 2 bits are left for transparency this FX10 mode is kept within the standard 32 bits, which is ideal for performances. ATI doesn´t seem to take advantage of this, however.
Like in Far Cry, the X1Ks are the only ones to combine HDR and MSAA.
