How to dedicate a graphics card to Lumion

Hi guys,
I have a good GTX card and a Quadro.  No matter how I set the Nvidia control panel to application specific, it KEEPS using the Quadro...  Highly annoying!  Other software does not have this problem.  Can someone please help?

Hi

Which version of Lumion are you trying to run on the GTX?

Can you do a screencapture of the NVIDIA settings so we can see what you have tried.

What leads you to believe it is still using the Quadro card?  If it is the Lumion Benchmark and if the Quadro is the first system GPU card, then the Benchmark (derived from DirectX reports) will only show the prime card as the one in use.

Please also attach your Benchmark report (screencapture), and the DXDiag report (txt file).

The recent competition version.

See below.  But also, what should I 'try'?

Yes, it's the benchmark - it says 'Quadro' and gives a low graphics score.  But also, when I open Lumion, the 'system speed' on the splash-page reads only 4140.  In use it seems fine but rendering a movie is excruciatingly slow.  I thought a Titan should do better.

Please also attach your Benchmark report (screencapture), and the DXDiag report (txt file).
Attached.

Thanks for your help.

Hi

Thanks for the information.  Certainly a Titan works really well with Lumion and creates fast renders.

AFAIK, you should see a step 2 in the NVIDIA Control Panel that lets you select the preferred graphics card (similar to the image shown in this topic:  this topic.

Your Control Panel does not show that, and that may indicate a problem with installed drivers.

I note that the DXDiag report shows an old GTX 460 driver, and wondering if you will need to try uninstalling and then reinstalling drivers to see if the Control Panel shows the selection.

It may also require complete removal of drivers by reinstalling Windows, but thats a last resort sort of thing.

Users with 2 cards have generally been also running 2 monitors, some of this information in this topic may help: Two monitors (and multi-cards).

Would you please add your Lumion Competition license key to your forum Account (click here, scroll to the bottom and enter your license number).

Also, one further thing to check:  is there a Preferred Graphics Processor drop-down list in the Control Panel tab Global Settings?  If so, what is it set to?

Is the "preferred graphics processor' option not only available for 'M' cards (laptops)?  It's not on my panel.

I doubt that.

I do cuda rendering.  The competition is for my daughter and this machine at work is the most powerful.  That's why there are 3 cards...  Uninstalling a stable driver on a work machine is a last resort for me.  I am not having any other issues with high-end graphics apps.

Users with 2 cards have generally been also running 2 monitors, some of this information in this topic may help: Two monitors (and multi-cards).
  I can't access that forum, even after registering the license...??

Would you please add your Lumion Competition license key to your forum Account (click here, scroll to the bottom and enter your license number).
Done.  But does not help to access other forums??

Is it possible that you could check (not on a laptop) if you Nvidia Control Panel has the 'preferred graphics processor' setting you refer to?

Thanks!

I'll have to ask someone in the general forums that has a two card set up.

Yes, sorry that topic is in the Commercial Section.  Here's the main post of interest:
Quote
I have two cards, a Titan and a GTX 660ti 3gb. I also have two monitors (both Samsung 32")
I have connected my monitors to the GTX 660 and this serves as my default video card. In the Nvidia settings I have set it so that Lumion only works with the Titan (I tried selecting both cards and when I did a speed test it auto selected the 660ti, so now it only uses the Titan) This setup is great also for GPU rendering in other apps like Thea render where it's set to use both cards, however the share is 100% of Titan and 50% 660ti)

Hi seekerfinder

One option that a member uses is for each GPU to run it's own monitor (was for identical GPU's). 

You then just select the monitor for that GPU and set the applications 3D parameters for Lumion (as if each was operating independently as in a single GPU/monitor PC).  So you could set the Titan for one monitor and when you run Lumion, it will be using Lumion.
