RT-GPU always slower than CPU

[KiboOst]

Hi,

We just installed VRay 3.50.3 and it confirms what we always saw:

When using VRay-RT, cpu mode is always faster than GPU or OpenCL.
We use win7SP1 x64, max 2014 uptodate, Corei7 6850K 32Go ram, EVGA GTX 1070 8Go
On two fullHD monitors

Is this something normal, or is there a magic settings somewhere to make VRayRT GPU fast ?
We are working on arch-viz animation scene, mainly IR+LC.

Thanks

It shouldn't be slower. Can you send a scene for us to check ?

Best,
Blago.
