Lumion - Problems with running

Hello, after having properly installed Lumion, the home menu screen appears and everything runs ok. After that, after I press the NEW button in the menu, my laptop tells me that the graphic card reader has stopped working and it terminates the program. My graphic card is NVIDIA GeForce GT 540, 2GB VRAM. In my opinion, it should be strong enough to support the program?

Thank you in advance

Hi Danail, I assume you mean the 540M?

If so, you'll need a faster graphics card to be able to run Lumion properly:

In addition, if your laptop uses Optimus technology, you'll need to configure that before running 3D applications. Here's how:

Hello,

My video card has 2GB of memory - this is the model of the laptop I am having difficulties to use Lumion on - http://reviews.cnet.co.uk/laptops/acer-aspire-5755g-review-50005088/
It has no problems using other heavy 3D applications. What is strange for me is the fact that I used Lumion on a machine with far weaker configuration before.

the problem described here is quite the same as mine - The same problem with program (latest with SP2) crash (videoadaptor stops working) with a further system crash (blue screen). win7 x64 NVidia GeForce GT555M 2 GB + NVidia Optimus  (Intel HD - the 2nd graphic card) 8 GB RAM

How can I check if my system uses Optimus technology anyway?

2) Have you already added Lumion to the list of applications in the Nvidia control panel  -> Manage 3D settings, and have you set the "preferred graphics processor" to "High-performance Nvidia Processor"?



I'll do that and then I'll tell you again if there is a result :)

Try googling for "Acer Aspire 5755G optimus".

All the search results confirm that it's using Optimus technology (typically a slow Intel-based card for 2D applications and a faster card for 3D graphics), so please follow the procedure in my previous post and let us know if it works.

Hi Danail,

I have the same laptop and indeed it uses this technology. Here are a couple of screenshots of the steps you need to make to set nVidia as your card for Lumion.

My system is Hungarian (Win 7 64 bit) but hopefully the screenshots will hel identifying the individual panels.

First, go to your system control panel and select "Hardware and sound" (or what):



There, go to your vide card settings (maby already saying "nVidia settings" and find this (nVidia control) panel where go to 3D settings. Here you can set nVidia as your preferred card in the global settings.



In this case, unless you specify differently under the Program specific settings (there is always an option to use global settings), the above setting will be used.

You can however go to the other tab and select Lumion (here SketchUp is displayed as originally I made these screenshots for the SU help forum) and define specifically that it should use your nVidia card.



That's it. This card is not particularly strong to run Lumion very effectively but I guess it is good enough to put some smaller projects together. If I had had twice the money, I would have ended up with a better laptop but since it's almost exclusively my wife watching videos on it, I do not think it would have been a better investment. :)
