Right, that's a known trade-off we had to make. Our old tone adjustment could get by with the DX7 fixed function pipeline. The new tone adjustment needs Pixel Shader 2.0 to do high dynamic range and color management, neither of which the old did.

Can you give me an idea of how prevelant Pixel Shader 2.0 is?

It came about about 4 years ago? And it's required for Windows Vista "Aero":
That said I don't know what percentage of cards out there have it, but it's the minimum we could get away with for our tone adjustment.
