Gpu render with geforce rtx 2080 ti

Hi Everybody

HEEEELPPP!!

I’ve correctly installed in my pc V-Ray Standalone and V-Ray for Blender.
During the render appears that V-ray next is now use only 2% of my two Geforce RTX 2080TI 11GB.
The hardware is working properly with Cycles.
I’ve also tested my hardware config with your Vray Benchmark, and following the ranking it seems a that V-ray Next works better with a GTX 1080 than a RTX 2080, allthough this latter has double amount of CUDA.
Is there any specific drivers for RTX technology I don’t know about?
Is it a matter of waiting for the next V-ray future release, which will optimized RTX tech?
Do you confirm that currently V-ray Next works better with GTX than RTX?
Thank you for support.
