FSAA+HDR on NVIDIA?

I thought that Nvidia couldn't use HDR and FSAA at the same time, but yesterday I was suprised that when I went to play DoD to see what it would do on my new SLI rig I saw that I was running both?!?!? Then, today I told a BF2 clan member about it and he said that you could do that and in fact he was doing that. I just thought that you could only run them together with an ATI card.

Does anyone know the specifications or the limits to using these features between ATI and Nvidia?

DON'T SCARE ME LIKE THAT :|
(I got all excited for a minute) :p

DoD and all other source games use Pixel Shaders or something to that affect to do their HDR. It takes longer to impliment, but is often more compatible which I think thats why they choose it for the Source engine.

It's not fp16 or fp32 with AA which they still CAN'T do (which every other HDR game uses).

Nvidia can only do HDR + AA in Source-based games, like DOD, CS:S and Lost Coast. Those games implement HDR via pixel shaders, and thus it will run on any DX9 hardware, even with AA. Other games, like SS2 and FarCry, use FP blended HDR and NV can not do MSAA with HDR in those games.

I got a question, can NV to SSAA with HDR?

Yeah it can, most likely dirt slow since MSAA + HDR is slow enough already.

Oh ok, thanks for the info. I was just shocked/excited when I saw that happen. It looks really good with how Source did it. I've got Far Cry and the HDR on that, I think, isn't as good as Source's is. Of course, maybe that's because it's in the beta stages for the official patch that will release it. Why do the other engines use it differently so as to lean to one company? I mean, if I were a business I would want to provide that feature like Source did and make it available for both Nvidia and ATI.

Oh, one more thing. Can regular HL2 implement HDR+FSAA like HL2:LC, CS:S, and DoD? Because I keep the same settings that I do when I play DoD (the same ones that let me get them both) and when I use those and play HL2 I don't notice it. Do I need to do something to enable it?

No, you can only use HDR+AA on the Lost Coast level.

HDR+AA is turning into this gens "True Form", a check box feature unused by games.

No, it's just taking the normal amount of time to make its way into games. SM3.0 was loudly touted as "The Feature" to have, yet a year later there were less than a handful of games that actually used it.

That could be true.

It may well be that 1st gen HDR+AA proves to be sort of a moot point, like good DX9 was on the 9700Pro vs 5800U. By the time DX9 titles came out, you didn't really want a 9700Pro to run them anyway.

So I agree it will likely be the case HDR+AA will be too weak on current hardware when games get around to using it, and we'll want ATI or nVidia's next card for that.

Good point.

I never said current hardware will be too weak. Perhaps todays cards will be powerful enough be able to run those effects on future titles, perhaps they won't.

Only time will tell.

Sorry, perhaps I misunderstood.

In any case, we can agree that 5 months after the introduction of EXR HDR+AA it's largely irrelevant.

Similar to how HDR was when first introduced on 6800 series. I see your point.

Only if the developer codes for it in the game engine, which is the case in AOE3, but the performnce would tank. Forcing SSAA in the control panel would not work with HDR.

Just like plain old primitive HDR and soft stencil shadows you were pimping a year ago, eh Rollo? :roll:

Didnt seem lacking to me when I played Farcry with HDR and AA.

LOL

How many times have you played Far Cry now Munky? I played it as much as I wanted to a couple years ago...

:)

I won't play it next year if they figure out some other way to make it look a little different either....

Rollo, nobody cares what your banned and now re-registered AEG paid ass has to say. Lucky for you there isn't a mod that closely monitors these forums for re-registered trolls like yourself.

Maybe there will be a beta patch for pac man. :roll:

At least the option is there. Beats having to use a shrinked rehashed core from the last year that has subpar IQ. I feel sorry for all the people who get taken in with nVidia hype and then have to use a core that needs emergency beta service pack drivers just to get OK performance in new shader heavy games like Oblivion and FEAR at the expense of OGL performance. BTW Oblivion benefits greatly from angle independent AF, I feel sorry for those new 7900 owners that have to put up with shimmer IQ in a great looking game like this because they bought into the nV hype.

As opposed to the hot, noisy, power hungry, subpar AA, crap driver, lack of support, follow the leader card you seem to support? People have been waiting 10 years for an OpenGL patch from ATI. Go back to Rage3D, as no one is buying your BS here.

I hear Serious Sam 2 supports HDR+AA, too bad your 2 primitive gtx's couldn't run that with all the eye candy.
