Hi Guys,

I'm presently in the process of persuading my boss to purchase Lumion and have downloaded Lumion free 3.2 for appraisal.

Due to the nature of work I need to be able to work on a laptop and have a Dell Precision M6700 with the following 2 graphics cards onboard:-

Intel(R) HD Graphics 4000
NVIDIA Quadro K3000M

I have switched the graphics to run Lumion on the Nvidia card with Optimus but for some reason this isn't being shown on the Lumion benchmark results screen. Is this normal? I'm concerned that I may not be getting the optimum performance out of the machine.

I have attached a screenshot for info.

Thanks guys... great software

Hi Goughy01

Welcome to Lumion and the forum.

No you are fine, you have done exactly right in using Optimus and setting Lumion to use the NVIDIA card.  It will switch as required when Lumion is requested to run.

The text listing the Intel HD Graphics card comes from the DirectX system data used by the Benchmark reporting, as that is the prime system card and it's not possible to detect the switched card arranged under Optimus.

If not already done so, please review hardware requirements for Lumion and the ability of Quadro cards re Passmark marks (1578) and comments in the forum.  Note Quadro based cards are more suited to CAD based applications and we have users that use such cards, but the ability to perform (well) for more complex scenes might be considered limited.

Thanks peterm for such a quick and detailed response  :)

So far Lumion has been working very well on the laptop and I'm getting some great early results. It's such a cool piece of software to use and brings a bit of fun back into producing visualisations.

I have a higher spec desktop machine at home with a Geforce GTX580 which would knock socks of this machine. Do you know if the Lumion licences are transferable? i.e. Is it possible to work on the laptop and then tranfer the files to continue working on the desktop when a little more "grunt" might be needed? Or would this require 2 licences?

Thanks again. The information is really helpful.

Hi Goughy01, yes - that's no problem. Commercial licenses are automatically unlocked when you quit Lumion, so that you can continue working on another PC. You just need internet access when starting and closing Lumion to ensure that the license is activated/de-activated correctly.

P.S. There's some information on how to transfer files from PC A to PC B in this FAQ post (search for WHERE ARE MY LUMION SCENES AND IMPORTED MODELS SAVED?).
IMPORTANT: Please do not send private messages and emails to members of staff - unless we specifically ask you to send us sensitive information, for example License Keys.

And to add to that, if you have a Lumion Pro license, then you can export your entire scene to a single (LS3) file which makes it much easier to work with, as well as allowing collaboration with others.
