Help! gpu acceleration not working

I have AMD Radeon R9 290x (4gb memory) connected to my system but won’t be able to render with GPU… Please help me resolve this problem.
motherboard: ASROCK N68-GS4 FX R2.0
CPU: AMD FX-8350

Sketchup version: 2019
Vray: 4.0

Vray GPU works only with Nvidia GPU.


I have nvidia gtx 1080, yet not working. I mean in the vray settings, gpu selection is not clickable

Search in Windows start “GPU selector” or something similar. In this little app choose your GPU. It should help you.

“GPU Device Selection”
