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.
