Thanks for the information.
1. How do you know how much VRAM is being used?
2. What is the Stats of your scene in Build Mode, top right corner? And, also from Movie Mode from a clip where Stats text is coloured red indicating heavy scene and effects.?
That message definitely indicates the GPU has run out of memory. Usually low memory shows up with the vertices being incorrect in some places, and strange triangles appearing. This does not always happen, as there is management to swap content off the GPU. It's also the GPU, and rest of the systems response times, rather than Lumion going slower as it tries to manage limited space.
3. Is it causing Windows to crash, or just the card drivers to reset?
Would you please add your Lumion 5 license key to your forum Account (click here
