BAH! HDR doesn't work on X800 cards, only 6800 cards, even though we've seen these kinds of effects on ATI hardware before. What utter nonsense!
F**king hell. Do these developers really need to pick sides when doing stuff like this? I can put up with it if they make it perform better on one hardware or another but to hold out features like this altogether!? A pox on them!
It probably was impractical to run it on ati's hardware. It can run, but it would require more passes to do the same thing as compared to nv's 6xxx archetecture. I also think they should have enabled it, but maybe they had good reason not to is what im saying. Or maybe theyre working on it for the "next" patch which we all know will come out within a '04.
I lost the link but there was an interview (perhaps at Sharky Extreme) about it and their excuse is pretty weak, and a thinly veiled ploy.
They talk about how for quality they decided to code HDR for FP32 instead of FP16 (they neglect to even mention FP24, which half of the market uses).
Then the interviewer asks something to the effect of "oh, so if it supports FP32 then it should work on the FX 5900's then (obviously with lower performance)" and the Crytek guy says something about "well, no, because the FX6800 has a type of blending technique that we use (so it's 6800 only)" .
It's bollocks - just a convenient excuse to cut out owners of older cards and ATI users for not having FP32 (funny, HDR seems to be working fine in HL2 on both ATI and Nvidia cards).
It shouldn't even be an issue of "ATI vs Nvidia," it's just common sense - support what your userbase runs. Perhaps FP24 would run faster than FP32 on the X800 series vs the 6800 series. So what? It's an apples to oranges comparison anyways, as the 6800 series is running it at a higher quality (whether this would make a significant difference or not in actual visual quality is currently unknown). It's just annoying. ATI has the support for HDR right there. It runs fine in RTHDRIBL and Pixel Shader demos...
