Render View behaves weird

Rendering V-Ray
, ,
1

Hi guys,

I am working with Rhino [for windows] and V-RAY for almost 10 years now.

Something strange happened today.

While zooming in/out and changing from render view to ghosted view solids keep dissapearing, or showing inaccurate locations. Vray materials not showing correctly [more than the expected]

And the file becomes VERY slow with navigation.

I updated the drivers of my graphics card [NVIDIA GFORCE GTX 1050 Ti]

Please help!! I have a tight deadline with my clients.

if you work outside of a dropbox (save the file and render assets locally and work from there)
does it get better?
