Right Now Do any ATI cards support HDR??

HDR can be done on most any card however the performance hit can make it unplayable. The Geforce 6 & 7 series cards include a 16bit floating point frame buffer, which allows for hardware acceleration of HDR. Using FP16 HDR games such as Far Cry, SC, etc. can have HDR enabled and still have a reasonable frame rate to play the game. It is rumored that the next ATI chip will include support for FP16 HDR.

FP16 HDR (such as OpenEXR) is the preferred method because of the specific hardware acceleration that can be used without having to use the pixel shader rendering (which is busy doing other aspects of the game).

Exactly. The only downside to Floating Point Blending HDR is you cannot use AA.

Other was such as Pixel Shading HDR, should allow for AA... however, the performance hit via the pixel shaders will be much greater than that of the Floating Point Blending; it also AFAIK will not look as good as the FP-Blending HDR.

As, far as im concerned though, something is better than nothingl but i would rather have FP-Blending.
