[QGIS-Developer] QGIS 3D and Graphics Card Requirements

[Jean Felder]

Hi Luke,

The higher end card should indeed give you better performance.

However, there is a hard coded limit in QGIS 3D at the moment. A 3D 
scene cannot load more than 500 Mo of 3D objects even if you video card 
has a lot of available memory when the 3D scene is created.
The idea is to avoid out of memory crashes or GPU hangs. For example, a 
lot a 3D scenes could be loaded or other program may consume some gpu ram.

Benoît de Mezzo and I have been trying to remove this limit but the code 
is not ready yet.

Cheers,

Jean
