No HDR on NVIDIA cards

[dscowboy]

Woah... remember all those bloom and reflection HDR lighting effects in the latest video? According to Beyond3D the NVIDIA cards won't render those at all with current drivers:

http://www.beyond3d.com/misc/hl2/index.php?p=6

present NVIDIA drivers do not support any floating point rendering targets and hence HDR would not operate on NVIDIA's DirectX9 boards.

I thought the FX cards could perform all the DX9 functions, just poorly. Can anyone more knowledgable clear this up? Haven't FX owners been able to run those HDR demos that have been linked to from this forum?

20 FPS between 5900 and 9800 is a fairly big deal... but FX cards being completely incapable of high-profile DX9 features? That's huge.

yea... ouch... That will suck for people with the FX cards...

I feel sorry for you.

Or maybe you were seriously... on that note, whats wrong with you?!

the hdr demo that was linked was a 'video' so any one can play it, any video card can play a video.

ofcorse im serious i dont want all my lights and reflections all blury and shit.

that shit looks ghey

No, that's not what I meant. I'm talking about the completely separate, non-HL2 related demos out there that people can use to show off DX9 effects on their cards. EXECUTABLES, not MOVIES.

 

[Direwolf]

That's distressing if its true.

[Mountain Man]

What's HDR?

 

[scribblehead]

High dynamic Range rendering....sheesh that took 2 edits, to get it right

 

[Direwolf]

Its mostly the effect of not being able to see in dark places from light areas and vice versa.

 

[dscowboy]

High Dynamic Range. The 'bloom' effect seen in the latest video (where the light through the holes in the ceiling is bright enough to partially occlude surrounding geometry) is part of HDR. So are the reflections on the tiles of the roofs.

EDIT: The antilion/roof video to me looks prety 'magical' and a lot more photorealistic because of the HDR effects. Apparently it wouldn't look anything like that on an NVIDIA card, which seems pretty strange.

You saying this because of:

It says Nvidia DRIVERS do not support HDR. This is something Nvidia can and probably will include with their 50 driver series.

It will probably look like crap if Nvidia keeps up the bad work.

 

[shapeshifter]

yes they can probably include them on their drivers, but there fps will drop from like 30 on the 5900u to probably like 15-20 fps, so that will suck.

 

[Mountain Man]

Alright. Thanks for the explanations.

This doesn't really concern me because I have a Geforce 4 Ti4200, so I'm stuck with DirectX 8, which Gabe said will give visuals on par with what was seen in the E3 videos (which isn't shabby by any stretch!). Still, if it weren't for the fact that ATi's Linux support was non-existant, I might consider an ATi card as my next purchase, although rumor has it they are looking to port their latest Catalyst drivers to the *nix platform.

 

[Piecemak3r]

well i must admit that i've been an nvidia fan boy ever since i bought my ati fury back in the day and was very pissed off at the driver support. But alas, my poor nvidia days are dead (at least until they get there sh*t together :/ ) I guess i'll be buying a 9800 soon *sigh*

New Linsux drivers have been released at the same time as Cats 3.7s.
There's a Linux Beta Testing in progress too.

I really hope NVidia shapes up...

I used to really like their products. Bummer for the NVidia boys here, this is why I don't like the whole concept of fanboyism...

 

[kider]

i can run the hdr demos with my nvidia card... its runs alright... not the fastest but about 20-30 fps on most of the lighting effects... i have a fx 5900 ultra 256mb by the way... just so you know.. the card is capable of running hdr effects...

I know exactly what you mean, I had a bad time with my Fury card a few years ago and said I'd never buy another ATI card, but having looked carefully into it I went back to ATI (9800 Pro), when I bought my new computer in July. It's a very good card with very solid drivers, I'm pleased to report.

The demo works on my fx5600 as well, although at a mere 5 fps.

No. It's a video, not a real-time rendering. Your card is not making those HDR effects, sorry. ;(

That's because the nv3x series doesn't run DX9 in HL2, it something in between 8.1 and 9, they had to create a whole new path to render through. It's neither pixelshader 1.4 (dx8.1) nor ps2.0 (dx9)
It's called the nv3x path I think.

 

[Incitatus]

I wish people would get the concept behind HDRI's down, it's bit frustrating to see people talking about HDR lighting while they obviously have no idea what it is.

HDRI - High Dynamic Range Image

These files are used as a light source instead of traditional point lights or area lights, its a form of image based lighting. The range of values that the pixels of the hdr image can contain create a VERY realistic lighting.

Pixels in a traditional bitmap can contain a brightness value between 0 and 255. A pixel in an HDRI can contain values between e.g. 0 - 20000. And these values are realistically scalebale which means you can change the 'exposure time' of your HDRI to create different, but still equally realistic, lighting values in your scene.

At least, I was. It's definitly not a video. I could toy around with the camera and glare effects in real time. That is, if you can call 5 fps "in real time".

O.K., perhaps I should not have said that ATi's Linux support is non-existent, but the reality is, the current Linux drivers are pretty much shit making ATi's Linux support virtually non-existent. The new drivers certainly look promising, but ATi has done a piss poor job keeping the Linux community informed about their progress.

True. The stupid thing is, Beyond3D never said which path they were testing the NVIDIA cards on. If they tested NVIDIA cards on the mixed-mode NV3x path, but ATI cards on the full DX9 path, you can't make comparisons between the results, NV3x is poorer image quality. If they were testing NVIDIA on the full DX9 path, then HDR effects should have been rendered on NVIDIA cards... doesn't make sense to me.

 

[A2597]

or it could just be that Nvidia messed up even more then we had thought, and really DIDN"T add all that cool DX9 code...

 

[MaDMaXX]

The cards DO support it, they are dx9 cards, but the effect is not currently enabled in the offical release drivers, i suspect it will be in the det 50's.

 

[Mother]

So is the mix of DX8.1 and DX9.0 that runs on the NV3X known as DX8.55?

But people with FX cards on this thread are saying they're able to run the DX9 demos (I am NOT talking about MOVIES, people, EXECUTABLE DEMOS that are not HL2) that show off HDR effects. And Detonator 5x drivers just became publicly available a couple hours ago.

 

[kider]

i wasnt talking about the video.. i was talking about the benchmark program... it is my card rendering it after all eh.... :cheese:
