Over the next month or so there will be a couple of interesting releases via Steam, in addition to the upcoming Counter-Strike map de_compound.

First, we'll be releasing an update to Half-Life 2: Deathmatch that will include the Slam, Stunstick, and the Crowbar. We're not ready to release the contest winning maps just yet, but we will be releasing a new map we've built at Valve to tide people over while we sort out the contest winners. There will also be a release to Counter-Strike: Source around the same time that will address a few minor issues.

One feature that we'll be adding to the Source engine in the coming months is high dynamic range lighting. To showcase this we've taken a part of the Highway 17 chapter of Half-Life 2 and worked it into a single level that incorporates HDR along with some new gameplay. We're calling this short level "The Lost Coast," and it will be made available free of charge to Half-Life 2 customers that meet a specific set of high end hardware requirements. We'll be publishing those requirements soon.

Below are a few early concept sketches of the level early in its development.
I hope they dont have only the high end ATI's getting HDR.

Yeah HERE (http://pc.ign.com/articles/585/585596p1.html) is the IGN preview talking about it.

This is the ATi levels we have been hearing about for so long!

Now we get to take bets of weahter it 'supports' nvidia products yet ; ) ; )

I hope so. If they dont, im sure someone might figure out how to get it to run on nvidia cards.

Yeah what about that 3DAnalyze program?

Of course they will, Nvidia has 3Dc support through the driver. :)

From what I gathered from that post, they said that you won't even be able to download the levels unless your hardware meets their "high-end" requirements

Great .. now we know when the R520 will be launched ;)

These aren't really "new" levels then, are they? All they did was take the existing level and add HDR. It's not any new areas or anything. Weak.

Look at the concept art. Where in HL2 is that "high walled keep on the cliff" or that character?

None of us know how much they did, but its obviously more than just adding hdr.

If they don't, I don't think I'll ever buy a Valve product again.

They will support nvidia because there is no (technical) reason to do it otherwise except maybe a nice big check from ATI...

That's what I'm afraid of. The Valve ATi love affair is sickening, and who knows what ATi'ed pull to dominate the market once again.

Well, I geuss they'd have to support nVidia if they are going to release the showcase level "over the next month or so", as the 6x cards are the only ones capable of true HDR right now, so there is hope...

Bah higihway 17 was long and boring. why not make a new map or release a map from thoose videos that were only shown at E3 that would be cool but no :(

Valve is going to release a new map for HL2 SP soon. The HDR map is a map from the coast scene not seen before.

No...it's the same highway scene, apparently they're just adding a little bit to it.

Rthdribl HDR demo uses FP16bit per component, which is true HDR, and works fine on Ati hardware. It's the blending required for openexrHDR which Ati lacks, but this blending can be done with a workaround.

Got it. Sorry, I was under a mistaken impression, apparently. My bad.

Yes, the RTHDRIBL demo uses textures which have color information stored in FP16 per component, the actual HDR calculations however are being rendered and displayed in 8-bit/16-bit Integer, that's why it also works on ATI cards.

This method is NOT offering the same image quality as FarCry's FP16 HDR shows, this true FP16 HDR method only works on 6x00 cards.

oh and BTW, "OpenEXR HDR", as you call it, doesn't exist. The correct name is "FP16 blending HDR".

The blending indeed can be done through shaders, but it's noticeable slower than nvidia's "native" method and therefore I don't think that it will ever be used for real in games but most probably only in techdemos or other showcase demos (like the U3 engine)

So in the end, calling the one or the other method "true HDR" is wrong and correct at the same time. Both method are true HDR implementation however only the 6x00 cards can render a "higher" precision HDR (still not quite "high" precision HDR but rather "medium" precision HDR) and all other PS2.x cards can render a "lower" precision HDR or simply "low" precision HDR.

But all implementations are true to the HDR specifications.

Valve uses 16bit integer buffer HDR for Ati cards in HL2:

Looking at the Source HDR demo movie (rendered with 9800Pro) it looks like that FSAA is working. That's a big plus in comparison with FP HDR.

Heh,that is tricky PR. If you read his statements carefully, he is saying that their HDR offers Integer 16-bit precision (he says values [0,16] which means integer). When he mentions floating point and nVidia not using floating point, he is referring to the shaders and how the FX5800 had integer 12-bit precision for shaders. Meanwhile the current 6800 series beats ATI cards in HDR handily.

Anyway, not too much of a concern to me since I returned the game :)

FSAA is nice, but every demo I have seen of integer 8-16bit HDR has looked extremely poor compared to floating point 16bit HDR, sometimes it looks worse than when HDR is disabled.

this reminds me of farcry, everyone is gonna sit here and speculate what method of hdr it uses, argue back and forth, sit in anticipation, and then b*tch about how ugly and over-exposed it makes everything look when it is arrives. Sometimes I wonder why developers bother, they never get any positive feedback from communities.
