Hello,
I’ve find something strange on GPU mode if we use a simple Vray material with a map on RGlossiness slot.
Because picture are more clear than my english, take a look at it 
Without this RGlossiness map, CPU and GPU are done the same job .
With Rglossiness map, the openCL kernel give some strange square and don’t blur … So it’s bluring my reflection at some place if you look carefully ! it’s near to work, but it’s not fully work and create a strange reflect.
The Blue matrial isn’t identical on GPU and CPU because VrayBlend is unsupported in OpenCL . it’s good that Vray wrote this sort of info for us on the active shade
The GPU is a lot more fastest than CPU, it’s not a news But it also give less white Dot !
So .. back to the strange reflect. It’s a bug or an unsupported feature ?
