I have been trying to run, Lumion 3D Architecture Program but it does not run on the proper designated NVIDIA GeForce card. Instead it runs only on the Intel 4000 card so then the graphics are horrible and lumion doesnt work as its suppose to. It states that my laptop needs better graphics card but thats because it doesnt detect the NVIDIA card that my (Toshiba Qosmio X870-Q7280) laptop has, which should be well more than enough to run lumion. I have tried all the suggestions that i have found online, such as changing the settings on the NVIDIA control panel, Changing the settings on the device manager, right clicking the lumion icon and selecting "run with high performance NVIDIA", ....etc. I have even gone on to the NVIDIA support forum But nothing has solved this issue. If theres any one that could help me ASAP i would extremely appreciate it.

these are some of the specs of my laptop

-Intel Core i7-3610QM 2.3 GHz (3.3 GHz with Turbo Boost Technology 2.0), 6MB L3
Cache

-NVIDIA GeForce GTX 670M with Optimusâ„¢, featuring 3GB of
GDDR5 discrete graphics memory

I am attempting to use Lumion PRO 4

Hi

The card is OK, but only just OK to run Lumion.  It's Passmark 1931 is just above minimum recommended of 1500.

There are occasional times when Optimus does not switch correctly, probably due to driver install and re-installs etc.

Which version of Lumion Pro 4 are you using?

As you have tried everything else, the only remaining suggestion, that has worked for a couple of users, is to re-install Windows.  This will clear all drivers, so after doing that, update to the 330.87 driver.
