Radeon Pro WX7100 compatible with V-Ray NEXT GPU?

[CMP_Design]

I need help please. I am using 3ds Max 2019 with V-Ray Next with a Radeon Pro WX700 graphics card.
I have set my renderer to V-Ray GPU Next and when I look down the the V-Ray GPU Render Devices Select, the Engine type is set to CUDA and only my CPU is shown.
When I select OpenCL I see the device names appear for the GPUs. I have tried both Engine types and none are actually using the GPU's when I check the performance. I have also tried changing the Display Drivers from Nitrous Direct3D 11 to Legacy OpenGL when I switch to OpenCL on the Engine type.
Am I missing something here?

Hey there,

If you don't have an NVidia GPU, the CUDA tab is expected to have the CPU only. AMD GPUs do not support CUDA.
AMD GPUs only support OpenCL so you have correctly switched to the OpenCL engine.

What you are experiencing is strange. How did you measure the GPU performance? What tool did you use?
Do you get any progress on the render at all?
