Title: Nvidia Quadro
Post by: samardac on February 24, 2015, 10:14:42 am

Will NVil work better with Nvidia Quadro?

Also does NVil depends on Video card? Or it is no meter witch one to use? I had expensive game card but it was broken and now I put cheap 45 USD NVida card and can not understand if something was changed in view port navigation, looks like everything stay the same. So what card is good for NVil or it is no matter witch one to use?

For screen/viewport navigation the GPU(graphics card) is used, but for object translation/rotation/scale, CPU is used.

Nvidia Quadro (or an AMD Firepro) will not give any better performance for Nvil than a regular gaming card.

steve, tell me pleas, now I have this card http://www.asus.com/Graphics_Cards/2101GD3L/, have I bought something better? Does it change something?  What is the rules for video cards for NVil?

It will depend on the models you build / how many polygons. The more polygons, the better card you will need for good viewport navigation.
If you are not having any problems/slowdowns with the card you have, then keep using it.

I curently use mid range Nvidia/AMD card (GTX580 or HD7850) and they are good for Nvil.

It uses Open GL? Also as I understood it does not use Cuda.

Nvil is using SlimDX (http://www.slimdx.org/) which is currently set to use DirectX 9

A ok, so it uses Direct 3D, that is why it is not so sensitive to Video Card?

I talked with developer of MoI and what he said about MoI video -
Hi Andrei, MoI does not really need the special "high end" cards - those are mainly for OpenGL programs. MoI uses Direct3D and is not as sensitive to the graphics card vendors limiting driver functions as they tend to do with OpenGL.

Looks like the same thing is with NVil.

Steve,
can you you download this file and tell me what fps you have rotating Viewport usig GTX 580? Make sure NVil is maximized and only it is opened. Tell me what shade mode you use when navigate.
As you said CPU is not used when navigating so specs of your PC is not important.

If you're interested in other cards too, on a GTX660Ti and with your scene I'm averaging at 11.58 fps when orbiting around the object. In shaded-only view the average is about 23.77 fps.

Smooth solid with edges = 12.9 fps
Smooth solid = 25.6 fps

Thanks,
with GeForce 210 I have 2.5 without edges.
Looks like Video Card means.

Steve how managed to reach 25.6 fps?
I have a GTX 780 3gb - 1fps !

Please send me the settings from C:\Users\Vlad\AppData\Roaming\DigitalFossils

Hm, interesting, Steve may be you have some secretes settings ;D?

It is not my settings, it is just the GPU is used for viewport navigation. (I get the same fps with a new config)

Make sure that your GPU is being used, you can use (for example) MSI Afterburner (http://event.msi.com/vga/afterburner/download.htm) which will show GPU usage. It is possible SlimDX may not be accessing your GPU/Chipset.

little sorrow :-)

And what do the owners of gtx 780? Is there a method of optimization?

For example XSI twists 120 million polygons, and Nvil 600,000 face

Personally, I think that such a narrowly specialized program as Nvil must be productive

Title: Re: Nvidia Quadro
Post by: steve on February 27, 2015, 10:48:31 am

Did you check to see if your GPU is being used?

Title: Re: Nvidia Quadro
Post by: Darcvizer on February 27, 2015, 11:00:31 am

Yes of course.

Title: Re: Nvidia Quadro
Post by: steve on February 27, 2015, 11:11:36 am

Does that mean your GPU is not being used?

Title: Re: Nvidia Quadro
Post by: Darcvizer on February 27, 2015, 11:34:03 am

used gtx780

Title: Re: Nvidia Quadro
Post by: steve on February 27, 2015, 03:23:13 pm

If your GPU is not being used, then it needs to be reported as a bug.

I was looking a litle more at this. It appears that the implimentation in Nvil is possibly using the SlimDX sample framework, as the fps appears to be locked to 60fps.

I will start a post about it in the bug section.

If this option is on, viewport performance will be reduced dramatically

View > Object Shading > Back Face In grey.
