does Vray RT CPU automatically switch on cpu when the gpu memory is not enough to render a scene?

Enabling a mix of cpu and gpu processors, RT GPU renderize respecting the GPU missing features?

With GPU is possible to enable alpha on trasparent objects to do compositing?

If in the scene I have a texture of 4000x4000 pixels a mix of RT GPU+CPU renderize the scene resampling the texture size?

Best regards.

i think that when rtGpu swich to CPU, it's work like GPU but with the speed of CPU.

When i have setup my render farm in GPU to render in distributed mode , all my rendernodes refuses to use my GPUS and use my CPU instead.
the picture renderer was exactly like the GPU render of my worksation. Even, if i switch my workstation, the cpu render is different than my gpu render.
so, when you start a GPU render, and then it's switch automaticly to cpu, it's working like GPU .
that's really good .

now that my renderfarm use my GPU, it's better again . It's soooo fast !

How can I use only the CPUs in mixed mode?

In GPU mode my renderfarm starts always with GPUs
