test scene

Thanks you so much Vlado to always beeing here to enlight us !
You did a really great job about supporting your customers like that .

If Iray and Arion Do the job job by filtering the picture, it's a good thing i think . Everything that improve the rendertime and kill noise faster is welcome .
If it's degrade quality, maybe you can let us choosing if we want it or not with a Check box in the parameters. and maybe a slider to setup how much we want to filter the render.

Do you plan to add some filtering ?

1mn with 3x580Gtx
1 580GTX inside my workstation, and 2 inside a Cubix Xpander desktop pro 2.

[ghiom3d]

I've a strange result .

1 mn : 3x 580GTX ( 1 inside my workstation + 2 in a cubix Xpander )

1mn 10 sec : 3x 580GTX + 1x 480GTX( 1 580gtx inside my workstation + 2 580 GTX in a cubix Xpander + 1 480 GTX on a Render node )

Adding a 480GTX in distributed rendering make my render 16% longer !

That's not altogether surprising. Network overhead?

[vlado]

What is your network connection speed (e.g. gigabit or slower)?

Best regards,
Vlado

[ghiom3d]

it's gigabit everywere in my network.
I've only 2 turn ON the 2 computers wich are working for this test .

[vlado]

Ok then; did you change any settings in the test scene?

Best regards,
Vlado

[ghiom3d]

No , and i've render the scene just after without Gpu in DR in 1 minutes.
Redo with DR , 1mn10sec .
I've try with one of my scene ans it's faster with DR ... i think it's something in your test scene wich make it slower with Gpu DR. But i don't know what

Not bad Which driver version?

Best regards,

[dmeyer]

Sounds like you may have to find a scene that takes longer...

[vlado]

Well, that's trivial - it can just be let to run longer, f.e. not for 512 samples, but 2048. Then the result can be divided by four to get it down to the 512 scale - it will still be a valid measure for the performance of the setup.

Best regards,

the 2.00.02 one mixed with the 2.00.01 on some nodes.
