V-Ray | CUDA - Sampling Issues

Render: V-Ray 3.6

Engine: CUDA

 

When using the CPU engine the option "Use local subdivs" is right there under DMC sampler, but whenever I switch to the CUDA engine that option is no longer there, it completely disappears.

 

Therefore while on CUDA, my reflecion / lighting sampling is greyed out.

 

If I enable use local subdivs while on CPU engine and I switch to CUDA, sampling is no longer greyed out.

 

So I add reflections to my render elements, I leave my material reflection samples at 8, that render pass comes out noisy, I increase the sample to 256, not a single difference, therefore it was just a visual bug.

 

 

TL;DR:

 

How do I enable "Use local subdivs" on the CUDA engine if that option disappears completely?
