I have GPU rendering problem with some files because CPU, RAM and Hard Disk up 100% and when rendering finished is bad but with CPU is 100%, RAM stable and Hard Disk stable and rendering is good.
Windows 10 PRO 64 bits
I have 16 Gb ram intel i5-3570K
Nvidia Quadro P4000
I updated to graphic card’s last driver and this was tested on Sketchup 2016 and Sketchup 2017 with Vray 3.40.04. In Vray 2.0 GPU rending don’t run.
