1. 10 minute render



2. 100 passes = 44 seconds

3. CPU: E6850 @ 3GHz GPU: 2 x Quadro FX 5800

Render on i7 with 4 x GTX480 to follow shortly.

Hi,

Hp xw6600, Bi-Xeon E5420 2.5Hgz, 16 Gb Ram, GPU 8800GTS

100 passes : 1 min 22 sec

10 min:


should be interesting to compare it with mental ray, vray, vray rt and other solution (octane... smallLux) ?
Let see beside computer which is the best renderer for that particular image.

I think it's not fair to compare other renderers because they have different material structures.
But nevertheless, if you wanna test, you can do it with this obj file.

And thank you for the posts, friends. Let's keep going.

you are right but today there is so many solutions that anyone can choose, it's quite disturbing.

It is an interesting opportunity to make an almost clear gallery of the different renderer :
- rendering time for simple but close to production case scene (like your bedroom), but will need different scene settings according to the rendering engine.
- best settings
- for most 'realistic' rendering,
- or fastest render
this should be multiplyed by a factor based on the simple case time (like iray 100 samples for gpu accelerated and an MR version for CPU only)
- for a single pciture and a smal animation (camera + character)
- maybe a chart with the feature, and pros and cons with polls and rating
- we could even compare software with simple scene

I suppose this to be a difficult work but it can be very usefull for all of us.

Let s consider that we are currently trying to define the configuration of a few new computer, and it was so hard to finally find proof that quadro is far even powerfull than standard Geforce.

I think that the cg talk forum is the best place i know to handle and gather that kind of clear and real and solid information.

I may be dreaming, but Who is with me ?

Quote: something wrong with you or Intars5d

you get a better render time for 100 iterations but he gets less noise after 10 min.


You think with my gpu I should get better results? My gpu according to info from Nvidia official site has only 48 CUDA cores. Not so much of a power compared to those GTX cards. And my 100 passes render looked worse than 10 minute one.

Thumbs up

i7 2.8GHz
4 x GTX 480

100 passes in 11 seconds

10 minute render

Here is a comparison with V-Ray RT:

1. iray 10 min, CPU+GPU (1x i7 + 1x GeForce 480):



2. V-Ray RT 10 min, GPU only (1x GeForce 480):

It's interesting that the Quadro doesn't do that much better than a GeForce, now I don't feel too bad about not having a workstation card

but AA is off on the vray one

Very interesting results here.

But maybe I donīt get the point of this Iray hype. Mental Ray is slow as hell. Nothing new here for me. Then Iray is 10 times slower than MR. Mental Images told me for years, that their renderer IS physical correct. NOW there is Iray and NOW Iray is physical correct.

The renderings from this two renderers are more than just different. So "physical correctness" seems to be just a marketing phrase. You are unable to asure that every face in your scene has a "really" physical correct surface. You always have to tweak on geometry AND materials AND lights. So what is a physical correct renderer good for if the best you can get out of it is an estimation of what "looks like physical correct"?

If I cheat my scene just a little bit with 10 seconds effort, I can spare 2-3 hours of rendering time per frame. I donīt think that Iray will be a kind of production renderer for me. It is barely to slow for material editor. But I agree, itīs a nice toy and may be a little window to the future of rendering.

How about this: Put some cheap GTX 470 or GTX 480 in your renderslaves in you little local renderfarm. Then render with "VrayRT GPU" via Distributed Rendering on all your cheap cards over your intern network in nearly realtime parts of your scene with Vray RT GPU as ActiveShade Renderer. Tweak materials, geometry and lights and render the entire scene over the same network on CPU without limitations.

Sounds more of workflow to me. What I really like to see is some support from Vray for the Meta-SL shaders. I think thats the way to go (for every renderer in the future).

Regards
Claus

Nope, it isn't. It just has no filtering (same as box filter with 1 pixel).

Isn't iray unbiased and vrayRT a biased renderer?

Nope; it's all in the settings. iray can be turned into a biased renderer and V-Ray RT into an unbiased one. For this test, both had the same settings.

ah nice, both the Renderings Quality looks the same, but the AA from iray looks better and where come the black spotches at the VrayRT rendering?
