Toshiba notebook with 2 graphic cards

I'm trying to install Lumion Educational on a Toshiba Satellite L50-A-1CU notebook equipped with 2 graphic cards.
The first card is an Intel HD Graphics 4600, the second one is an Nvidia GeForce GT 740M.
Complete system's specifications are available here: http://www.toshiba.it/laptops/portatili/notebook-satellite/satellite/satellite-l50-a/satellite-l50-a-1cu/

When Lumion starts benchmark, it seems to recognize only the Intel card, getting very poor results.
How can I configure Lumion to use the Nvidia card?

Which educational version?

Please see: Laptop PC's - Integrated Intel Graphics:

See: How to Set Optimus for Laptops in topic problem with lumion.

Note: re Benchmark report will always report the integrated card as in use, but if Optimus is set then it will be using the NVIDIA card.

Also Refer further to how suitable a GT 740M is for Lumion:
1.  LUMION 3: Minimum hardware requirements

2.  Lumion Web Site: Specifications

3.  Passmark: Videocard Benchmarks

Thank you for your quick answer, Peterm!
It is Lumion Educational Free version.

Is there a way to force DirectX to identify the right graphic card, so to get the correct benchmark results?
Unfortunately, disabling Intel card will completely prevent Lumion from working! :(

No.  The prime GPU for the system (unless there was a way in BIOS) is the Intel, and DirectX sees that and reports it as the GPU in use.

We know that once a user sets Lumion to be used by the NVIDIA card then that is what is being used.  The Benchmark result is for the NVIDIA card, it's just the card name is incorrectly identified as the Intel one.

Thank you again.
I also tried to configure DXDiag to use Nvidia card, but nothing changed!

What is a Toshiba notenook with a good graphic card to be used with Lumion?

Hi IdeaImmagine, the Nvidia graphics card you're using is not suitable for running Lumion (our minimum of 1500 points is for simple scenes only):

We don't recommend particular PCs or brands, but perhaps some of our other users can give you some recommendations.

Thank you, Morten!

Is there anyone using a notebook to run Lumion?
