Valve's High Dynamic Range Explored

Day of Defeat Performance Tests
Half life 2 is one of those games that usually gives us pretty good framerates on a wide variety of cards. It's interesting to see how Day of Defeat: Source seems to up the ante (so to speak) in the graphics department, giving our cards a work-out even without the HDR effects enabled. The fact that the fps of all the cards without HDR enabled is similar suggests that there is some CPU limitation to the game. It's also safe to say that turning on the full HDR mode causes quite a significant performance hit, especially in the 6600 GT, the only 128 MB card that we tested.
In the past, we've noticed that ATI performs a little better than NVIDIA in Half life 2, and not surprisingly, we see the same thing here with Day of Defeat. While it's true that the 7800 GTX gets higher framerates than any of the ATI cards, keep in mind that NVIDIA's 7800 series is in a class above even the fastest ATI cards out now (although not for very long), and the fact that the framerates on the ATI cards aren't far behind says something here.

I actually meant to ask about the resolution too.In my own bench, starting from spawn point at anzio and then running to the other end of the map while doing some shooting with the bazooka, at:
1680x1050
4AA/16AF All High/Reflect All
MultiSampling AA
Forced Trilinear mipmaps
I get just over 70FPS
4400+ @2.65
BFG GTX @ 480/1360
2gigs mushkin at 241 1:1 2/3/3/8

Is it just me? In EVERY screenshot of HDR vs !HDR that I've seen, I've thought the !HDR looks better. Maybe I need to play and see for my self.wanderer27 - Friday, September 30, 2005 - link
I have yet to see where either Bloom or HDR makes things look better.AOE III - HDR/Bloom looks worse.
Day of Defeat - HDR/Bloom looks worse.
Oblivion - Bloom effect looks bad, haven't seen a shot of non-Bloom on this game yet.
Maybe it will do something for darkly lit games, but so far they all look too glowy (AOE), or washed out (DOD).
So far this looks like a useless technology they're trying to shove down our throats. Thankfully, in AOE you have the option to turn this crap off.
My advice to the Devs, stop wasting time on this and find something that'll actually make things look or play better.

The image with HDR is smoother.Frackal - Friday, September 30, 2005 - link
Frankly I was blown away by the graphics in DOD-S and I've played COD2, FEAR, BF2, etc... If you're running the right rez with all details turned up, its like being in a photograph much of the time.Valve should have gotten way more props for this
I hope I don't have to see you guys exclaiming how good FEAR's crappy graphics are if you ever review that game..
Anyway I love AT but I thought this really downplayed the impressive graphics here.

The very bottom image looks the best to me. Compare it to the top which has alot of the jaggies but witht he HDR the jaggies are missing, it looks alot smoother. Wish I had a better GPU then a 9700 pro.Bonesdad - Friday, September 30, 2005 - link
All the jaggies are definately still there, the entire image is just more washed out...I think the top image has richer colors. Not really impressed, personally.toyota - Friday, September 30, 2005 - link
all the jaggies are still there in the bottom pic. they are just a little washed out. its not any smoother.DerekWilson - Friday, September 30, 2005 - link
We did top end and upper midrange ... this was really just a taste though -- believe me, we'll have more benchmarks with this game soon :-)PrinceGaz - Friday, September 30, 2005 - link
Interesting article though like many others I was distinctly unimpressed by the static screenshots showing the "benefits" of HDR. Maybe it works a lot better while actually playing the game...The choice of cards tested seemed a bit strange to me though. Either a 7800GT or GTX would have been enough for top-end nVidia performance, as would a single good card from the X800/X850 line-up to show how ATI compares with their current generation (ideally figures from an X1800 would be thrown in, but NDAs currently prevent that). The omission of a 6800GT or similar was the main problem with the benchmarks though, as many of us have one of them and would like to know well they fare.
Along with the 6600GT for current mid-range performance, ideally you'd also include an FX5900/5950 series and a 9800Pro as not everyone buys a new card when a new generation of hardware is released. The 9800Pro is still very capable and should be included in all reviews, and an FX5900/5950 should be included too for reference even if it does suffer badly with modern pixel-sharder intensive games, so that people can decide if an upgrade is worthwhile. Anything less than those cards would probably be a waste of time for this review though as they'd be too slow.
In fact I'd say a 9800Pro and FX5900/5950 should be included in *all* graphics-card / game-performance reviews, in addition to the usual 7800, 6800, 6600, X800/850. You must have them lying around somewhere ready to drop in a suitable box I'm sure :)
I'm looking forward to the updated/follow-up article with additional benchmarks, I understand if time was pressing you could only test on a limited number of cards.
