X360 GPU emulate 30bit color with 24bit output + dithering?

[Dave Baumann]

then this 30bit range color can't be used for rendering?

I didn't say that. 10:10:10:2 is an acceptible rendering format. What I was pointing out was that Xenos is one of the first consumer 3D chips to introduce a 10-bit display pipeline (which was also introduced on the PC with Radeon X1000 series).

in integer, i presume
FP10 mode rendering it's not adapted for profit to 10bit color?

I thought Matrox won that one with the Parhelia?

Didn't they just have the first 10bit per component DACs, rest of the chip being capable of 8bit per component?

Probably it is the result of gamma-correction.
