to manage a scene 21.6 million points, what should I change to have a frame-rate highest?
The video card
or should I add more ram?

this is my configuration:

INTEL Core i5 Ivy Bridge 3450 - 3,1 GHz - Cache L3 6 Mo - Socket LGA 1155
SAPPHIRE TECHNOLOGY Radeon HD 7850 - 2 Go GDDR5 - PCI-Express 3,0
CORSAIR Mémoire PC Dominator DHX+ 4 x 4 Go DDR3-1600 PC3-12800 CL9

Hi,
Your CG and maybe your CPU in order to avoid CPU bottleneck....
cheers

the new Nvidia 780 is not in the benchmark yet ....
But it will cost less than the titan....

Thanks Gga,

and does anyone know why the video card radeon, appear to behave worse with lumion compared to nvidia?

Thats an old long story ;)  Called driver ...

If you plan to buy a new card go Nvidea...

What sort of fps are you getting?

Do you also do things such as placing objects in to layers to hide, alter Editor Quality Settings etc?

Hi Peterm,
my problem is the management of this old project.
I wanted to remake the images using the new features in Lumion, but when I deactivate the simplification of the texture, everything becomes white I can no longer do anything.
I have tried:
move the lights on a level that I deactivated
turn off the GI and reflections in editor
recharge the texture heavier with more light

I can handle the model with only the limitation of texture, it will be the fault of my system?

Hi 3dmarius

Thanks for those details.

Your system does seem to be fine and looks most likely to be able to handle moderately complex scenes.  Not quite sure how close your scene is to moderate or very complex with 21m points, but the card and amount of VRAM seem fine.

..when I deactivate the simplification of the texture, everything becomes white

Are you referring to the Setting: "Limit all texture sizes to 512x512..." ? (see attached pic)

There certainly were a number of changes "under the hood" for Lumion v3 over v2.

Any effects set in V2 need to be removed (after noting the setting values) and re-applied as new for Lumion v3 scenes.

1.  Presume no other applications are running at the same time as Lumion?

From you screencapture of the Scene, it does not seem as if there is much complexity to account for 21m 3d points.

2.  How many lights?
3.  From your My Documents\Lumion 3\Library folder how large is the file/s for the model textures (*.txx)?  I am just wondering if there are some extremely large textures used in one or more models.
4.  What screen resolution are you running?
5. Could you please go back to the Benchmark tool and run the DXDiag and post here.

sorry can't be of much more help at moment.  May have to directly take a look at your scene including imported objects to ascertain how heavy things are for v3.

thanks peterm

 "Limit all texture sizes to 512x512..." yes it is!
1.no, non more application open
2. the light are on a layer desactivate
3. i must see at house
4. 1920x 1080
5. i will post

I think I've figured out what the problem is.
The fact is that the scene was conceived in Lumion 2.5 pro, on a computer that I had been given, and of which I was left with only the scene exported.

when the first time I tried to call in Lumion 3, I had problems and serious slowdowns.

I think I'm like you advice, to clean everything, and reload the 3d scene from the original files with the new FBX export.

I'm just sorry to lose the trees and plants, which I remember were long to be placed.

I will continue to experiment, in order to understand if this is the problem.

Thanks for your time.

Hi 3dmarius

Thanks for replies.

Yes, when you get a chance, it would be interesting to see what those texture file sizes are like.

The fact that the Limit Texture Size switch causes problems, the FPS and the other things you have tried sort of points in that direction.

As you have access to the source files you could also check texture sizes from the export files/folders.

A new import will/should help as in V3 there was an enhancement to optimise models on import and that will help the scene.  Do a new import rather than a reload.

If you take some higher up, top down screencaptures or quick renders of the scene, then it will be that little bit quicker to re-place the plants as you will already know where to place  :).
