VC ORB map problem

[Candy_max]

I'm trying Orb for the first time and the moment I adjust some map settings or just navigate the camera to have a better look, maps on the sphere lag, and sometimes the diffuse map disappears some times bump map shows in the shadow area.

In this image, both maps are lagging. What should I do? Help, please!
