In the viewport it takes a long time until the 3D model is displayed.

Can you help me, what could it be when I open the scene or switch from one scene to another, takes me a file quite long until the object (house pool garden) appears in the viewport at the other fils it goes much faster. at the fast about 1-2 seconds at this about every time 12 seconds. Strange is that the objects and materials loads very quickly, but the view is not. First I thought it was the Cosmos objects but also only partially, have now deleted them but still too slow. Is there maybe a list where it is pointed out what to look for when the view slows down? Because earlier I had the problem never Vray 3.7 since Vray 5 it is now occurred.

Hello alex_obrist,

Does this happen with a specific scene or any scene you try to load? Keep in mind that the size of the scene could affect the loading times. Could you please share the scene in question with us so we can have a look? Also, please specify the exact versions of V-Ray, Cinema4D, and your OS. Thank you.
