REALSTIC HDR LIGHTING EFFECTS WITH ANTI-ALIASING PROVIDES TWICE THE PRECISION OF PREVIOUS GENERTIONS.

Lumenex engine delivers 16XAA and 128-bit floating point HDR lighting at blistering frame rates.

Sure that isnt 128bit HDR?, FP32.. 32bit per channel, 128bit total..
Seems like a more logical step from FP16 then Full out FP128 (128 per channel, 512bit HDR...

Eh. That'd be nice, but: 1) no need for it, double precision fp is 64/80 bits, no need to go over that and 2) it would be slow, definitely too slow.

Although FP64 for each channel would be great not only for HDR, but for gpgpu, too. One of the great limitations of gpgpu right now, for, e.g., physics simulations, is the fact that all gpus out there are limited to single precision fp. There are methods to attain fp64 with fp32 hardware, but the performance hit is quite high.

Anyway, OT. :D

I believe this when I see it. Until then, it's wishful thinking.

similar in spirit to PureVideo and the Quantum Effects engines also featured on G80.so are they saying we are going to have to pay for hdr+AA?

No Quantum effects is actually a built in PPU.HDR+AA is not part of the physics engine.
Anyway whats with nvidia and having to pay for purevideo support.Isn't purevideo part of the gpus core that the consumer has already paid?Its like paying for driver support.

i was being sarcastic. i ment at as a jab as to we would have to pay for it all like purevideo. i think the reason pure video was a pay service had todo with dvd royaties.

All I have to say is, thank goodness the r300 (9700pro) came out a few years back :D

Really pushed both companies to make some solid stuff.

Can't wait to see what these cards are going to be able to do :D

I forgot the "?" in the post..
My point was that they prolly mean FP32 HDR, which is 128bit in total.
And not FP128.. FP128 would be insane, no idea if its even used anywhere..
I think the movie industry uses FP32, and FP16 when they dont need the full FP32 precision..
