Vray 3.6 for sketchup 2018

I tried ‘Vray 3.6 for sketchup 2018’ on the laptop with specification

‘Intel ® Core ™ i7-7500U CPU @ 2.70 GHz 2.90 GHz,

Ram: 12 GB,

System type: 64-bit operating system, x64 based processor,

Graphic Card: Radeon version 17.1.1,

Windows: 10 (64bit).

Software was working well till I was building grey structure, it start hanging after I applied material from vray with interactive render.

On the same system I used ‘Vray 3.6 for sketchup 2016’ and it is working better now. Can you please recommend changes I need to do in my system to be able to use ‘Vray 3.6 for sketchup 2018’ I find it better version and can find more objects from 2018 warehouse as compare to 2016.

Waiting for some help
