NVIDIA Demo: GeoForms

[fliguy84]

Have anyone tried this demo yet? It supposedly makes AA works with HDR in the demo :shocked:. This demo is targetted toward those with Geforce 7 series card, but I can confirm that it works with my 6800 too. And it looks damn cool IMO

It can't possibly enable HDR +AA on nvidia cards - thats impossible --- according to some on anandtech...

HDR with Antialiasing - Using one of several techniques to achieve high dynamic-range (HDR) lighting simultaneously with multi-sample antialiasing, this scene is rich in bright lights, glows, and reflections, while still having beautifully soft antialiased edges.

Too bad its causing my computer to instantly restart once I try to load it up, but thats probably an issue with my system :disgust:

 

[fliguy84]

Try lowering the resolution, AA or shader detail and try again. It stops giving me error message after I lowered the resolution and disabled AA

No use, I turned all of the settings on their lowest selections and it still did it! Wonder if it has anything to do with me using Windows x64? I really have no idea what it could be I am just speculating - but I do know that all of my games: BF2, CoD2, HL2 all work at maximum settings just fine as well as all of the other NVIDIA demos so who knows...

It is not impossible, Source does it. It is impossible to do both with any Nvidia card in Far Cry, though unlike you were claiming.

Or any game with "true" HDR, like oblivion:roll:

 

[P229SAS]

What is the difference between "true" HDR in Oblivion and that of Source?

FP16

Which is exactly why this demo cant possibly be using FP16 HDR.

Its not physically impossible, Nvidia could easily design a driver to handle HDR+AA if they researched it and built a driver from the ground up. Even if it gives unplayable frames, due to less shaders, they still could do it.

Well what Nvidia can't do right now is OpenEXR HDR FP16 + MSAA.

They can do OpenEXR HDR FP16 with SSAA if the game codes for it like Age of Empires 3, or they can do normal INT HDR through the Pixel Shaders as can any Pixel Shader 2.0 card in Source.

They can't do AA with HDR in FarCry and Serious Sam 2 to my knowledge, these 2 games use the method, they can't do right now. If I also remember correctly, no one can "officially" do HDR + AA in Oblivion either.

Demo worked for me on my 6800GT. *shrug* Looked kinda cool, but nothing amazing. And even with AA, only 2x and I think it was running at 640x480, lol.

LOL well i just read it and it makes absolutely 0.00000% sense to me. Anyone wanna make me a stencil? plzzzz

While they aruge about "officially," us X1k user are officially playing Oblivion with HDR+AA

"Using one of several techniques to achieve high dynamic-range (HDR) lighting simultaneously" - This would certainly be quite a change from when the 6800's were out and nvidia couldn't stop claiming "but we do TRUE HDR using the best possible format available (open exr)" Wouldn't be too shocked if this is the same method of implementation as Source.

Hence I said officially, I am aware that ATI released an unsupported driver to allow HDR+AA with the X1K Series.

Of course Nvidia was pushing it's advantage at the time when ATI didn't have OpenEXR HDR period.

I don't expect anything less from ATI trying to pimp OpenEXR HDR + MSAA in the current generation.

You make valid points and anyone who has objective intentions should agree... But you seem to forget that it's not ATI's fault that the devs conveniently didn't use FP16+MSAA option in their codepath..
Something that as it was proven was pretty easy...

I consider the situation with Oblivion fair enough, the Geforce 6/7 Series don't perform as well on this particular game, even R4xx based hardware can be competitive against Geforce 7 hardware. Since this game has great performance on ATI hardware, there is enough advantage on ATI's side to warrant even another ATI advantage with the official OpenEXR HDR + MSAA which current ATI X1K Hardware support and NV4x technology doesn't. The situation is fair enough for both sides as it is. Remember Nvidia isn't here to hurt themselves to make you happy.

This game is TWMITBP I think right, so you can't keep biting the hand that feeds you now can you?

It is not impossible, Source does it. It is impossible to do both with any Nvidia card in Far Cry, though unlike you were claiming.

Or any game with "true" HDR, like oblivion:roll:

HDR in HL2 is true HDR, its just done with a different method than other games

from Wikipedia:

High dynamic range rendering (HDRR or HDR Rendering) or less commonly, high dynamic range lighting (HDR Lighting), is the rendering of 3D computer graphics scenes by using lighting calculations done in a high dynamic range.

nowhere in there does it say "requires FP16"

That is the inherent problem with using vague terminology like the word "true", HL2 does do HDR, it just uses the INT thru Pixel Shader format that is all.

This one of the areas I have with "true" Dual Core. I don't like vague terminology.

FP HDR is more exact, can use any real number. Integer HDR uses integer only, and therefore only numbers without decimals (less exact, and also therefore less pretty.) This APPEARS to me to be FP HDR, but I don't know, nor does Nvidia make it evident either way.
