I’m getting very grainy renders from ProRender and when trying to use the new PBR materials.
The standard render engine is also producing very grainy renders.
Could this be caused by an incompatible graphics card driver?
- Quadro K620
- driver ver: 391.74 (newest)

attachments: material with grainy sample sphere
proRender sample
standard render sample

I’ve tried area lights and omni lights. both seem to make grainy surfaces when I use multiple reflection layers in the material.

Hi Michaelbp,

The hard ware and driver combinations are certainly a tech support part, please check with the support team directly:

Compatibility:

Rendering
“ProRender”, a new GPU based render engine
Based on OpenCL 1.2, working on Nvidia and AMD cards on Windows and AMD cards on macOS

From the images I really can’t tell a lot. Since it is for you in the Standard Render as well, are you using “Roughness” for the Reflection layers?
This is what I get going with multiple Reflectance layers:

If possible, for any question, share a scene file, reduced to the problem or if needed with dummies (if the original content is not for public use). But of course, it will not clear any Graphic Card problems/question…

Let me know how it render in the picture viewer.

Cheers
