running Lumion on laptop

Hi, everyone. First time posting in the forum here.

I just purchased a new Alienware 17X R4 laptop with a 3rd gen Intel i7, 24G RAM, 1 TB HD, and an NVIDIA GeForce GTX 675M.

With the 675M being a highly rated GPU for gaming, I had no idea until downloading the free Lumion trial that it was insufficient for running Lumion.

Looking at the NVIDIA site, the highest-performing GPU for laptops is the 680MX which also does not get a high PassMark rating.

All of the higher-rated GPUs on the PassMark list are made for desktop PC only.

So, is Lumion simply incompatible with laptops, or is there some other laptop-grade GPU that will meet or exceed the GPU requirements for Lumion?

Thanks in advance for any help and advice.

i have the gtx 675m in my laptop, too.

lumion is running without any problem with my scenes. (one very very detailed zoo scene produced some errors while rendering but not while working ..)

maybe you havent applied your nvidia card to lumion, and you laptop uses the onbaord grafik card with lumion.

you can choose via nvidia settings what program should use what grafic card.

hope this helps

Hi witttiger93

Welcome to Lumion and the community.

As stucki mentions, please check which GPU is being used for Lumion.  Details in this topic: Crash/Driver crash/Blue screen/"Not the same" error on laptop PCs.

In regard performance with Lumion; many laptop GPU's are heavily reduced in performance in order to balance with power consumption, so many of the similar versions to desktop are only half the power of a desktop eg a 675 versus 675M.

The exception now is the 680M and MX which have much closer performance and specs to the desktop GPU.  Refer NVIDIA and Passmark web sites, also I see the 675MX is much higher than the 675M.

Lumion can be pumping through a heap more polygons, textures and graphics processes/pos-t-processing than many games, but as gaming is the closest real-time environment to Lumion it is often used as a guide to specs needed.

Please refer to this post on specs for Lumion: LUMION 3: Minimum hardware requirements.

The key is also to note about complexity of scenes as to what and how much can be achieved.
Quality of hardware does also have an influence, as no 2 pieces of hardware or brand produce exactly the same performance.  NVIDIA cards seem to do better with Lumion.  VRAM is also an important factor, the more the better.

There are many users with less spec laptops, or desktops, than you have and do manage OK.  If you can swap out and improve on the GPU you have, then that will help with your experience of Lumion.

Thanks, everyone!

That was indeed the problem...assigning Nvidia specifically to Lumion through the Nvidia CP fixed the display issue.

Still, I was disappointed to find my brand new 3rd gen Intel i7 processor and GTX 675M are both kind of "meh" as far as Lumion is concerned (as shown in the meters under "Speed").

Thanks again for the help!

What is the NVidia graphics card?

Please refer to this post on specs for Lumion: LUMION 3: Minimum hardware requirements.

Lumion is currently in version 3.  All products (Free, Lumion, Pro and Edu versions) have the same system requirements.  Please also refer to the Lumion web site regarding the product versions and comparison for the differences in each.

Where as I know about this I think that there is something problem with your configuration. If it is best GPU for gaming then how it can not be fine with it. You should check out your n Nvidea setting for this purpose.
