the equality of visual quality in GT4 doesnt neccessarily mean ati is using a general PS2 codes, which is what futuremark is trying to measure in GT4.
You keep saying this and it doesn't make an inkling of sense to me. We already know
that ATI detects 3dmark03 and then optimized the shader routines in GT4. The sky shader and water shader optimizations only work in those specific situations. Of course they do, they are specific programs. How and why would they work anywhere else?
It's like saying that an optimization for Quake3 should work in UT2003, when they are different programs.
