Render Region settings seem broken in CUDA mode

[GregCooper]

Do the render region settings actually even work in GPU mode? Does dynamic splitting work in GPU mode?

Any change I make doesn't seem to do anything. The only thing I've found that makes a change is if I switch measurement from Region W/H to Region Count and all this does is change my bucket size from fairly large to tiny. None of the other settings seem to make a difference. This is in a completely new scene btw. I've got scenes I'm trying to render that keep hanging on the last couple of buckets cos its only assigned them to one GPU so I have to wait a couple of minutes for one GPU to finish the render while the others sit idle.

Both the bucket size control and dynamic splitting are intentionally not supported in V-Ray GPU for functionality purposes.

I see, well might be a good idea to hide it from the settings when switching to CUDA mode if that's the case. I was looking through help docs to see if this was supported on GPU but couldn't find anything so assumed it must be.

But it also seems to me like it would be better to enable both of these functions on GPU. Particularly dynamic splitting. I have frames with certain areas that take a lot longer to render than the rest containing things like SSS and XGen hair and my render is basically hanging on those buckets at the end as its only dedicating 1 GPU to finishing it off. It's basically forcing me to use progressive render for my finals as I can't match the speed with bucket rendering.
