Vray 3.6 for Rhino

[Pretty Picture Girl]

Hi Peter,

thanks, I tried that. The issue persists.
When I run a rendering I still get the same error message. mIght be also the Nvidia settings. Unfortunately Vray/Rhino is not listed in their settings list.
So for now I use the 3D Visualisation App Profile with:

-Open GL Overlay switched on
-Power management to Max
-Tripple buffering on
-Vertical sync on

Can you suggest which settings best to choose here? At the Nvidia forum I get suggestions to go to the Vray forum. Here I might get the opposite recommendation.

I plan to upgrade to a Nvidia Quadro M5000 in a few days. Hope that helps, it's the fastest card I can put into the machine without upgrading the power pack as well.
Honestly I am not so interested to know how my machine fairs against others. All I want to know is, will the graphic card upgrade solve this specific issue or not.

If yes I will upgrade, if no I will not. A simple answer would be all I want on this.
The new card has 8GB dedicated memory, the old has 2.5GB.

Kind regards Pretty

You could observe the GPU memory usage with an utility like GPUz. I suppose so 2.5GB is to limited. I would look at the benchmarks, my impression was that the GTX series should give you a lot of power for your money. But I don't know so much about mobile GPU.

Hi Micha,

thanks, yes I can see the GPU use in the Nvidia control panel. It says GPU utilisation is marginal when rendering with GPU&CPU in parallel via CUDA, but task manager also indicates that the 2.5GB GPU memory is fully used when doing so.
This seems contradictory to me.

Btw, the Quadro 5000 (which I have right now) and Quadro M5000 (which I am planning on getting) are both workstation cards the Hewlett Pachard P Z800 is not a Laptop. The mobile Quadro would be the 5000M not the M5000.
So far I was under the impression that the Quadro cards are better geared to rendering large still images and using very large files in Photoshop. I'm not doing any games on my computer, only CAD & Graphics and rendering.
Do you have experience using an GTX for that or should I stick with a Quadro?
I do not mind the way it displays on screen, but I do want nice results in the finished images, especially when printing them.

Thanks,

Pretty

OK, I understand. I used a quadro card in the past but there was no big advantage for Rhino. So, finally I bought a GTX1080ti. Also I don't play games, only CAD and rendering.

I looked at some benchmarks and if I'm not totally wrong than you get more more speed and more memory per GTX1080(ti) (for much less money).

The difference is so high, that I'm not sure ... . Looks like you could buy three GTX1080ti.

Great info Micha,

look what I found:

https://wiki.mcneel.com/rhino/nvidiainfo

That suports your comments and answers my question on best settings. At least with regards to Rhino.
Instead of the Quadro M5000 (=1290?) I could even get a Titan Xp (1299?).
Maybe overkill for my current machine, but I could still get it and than use it in the next machine as well.

Thanks for your comments.

I read a german review and the conclusion was - GTX1080ti is nearly 50% of the price and 95% of the calculation power of the Titan Xp. So, I would buy two GTX1080ti for the money. Only one card more and you get half render times.

Great! Thanks for the info. That will be my route then!

What value for GPU texture resize have you tried? There must be a max value which will help you overcome the CUDA error 2, you simply need to experiement a few times until you to find it.
The NVidia settings do not really affect V-Ray GPU. Just make sure you've set your device to max performance.
Regarding the render performance of different GPU models, as already mentioned, we can only advise result comparisons of the benchmark results at https://www.chaosgroup.com/vray/benchmark

Kind regards,
