Very simple scene - a product and a HDRI environment. Short times for an animation are needed and so I did some tests (1920x1080). (V-Ray for Rhino Next)
Cuda
1x2080ti..................22,2s
2x2080ti..................16,6s
2x2080ti+1080ti .....17,2
RTX
2x2080ti.................19,1s
I wonder that the additional 1080ti increase the render time. Also it seems to be the best to test RTX before using it for a scene.
Finally the best time I got per bucket mode and 2x2080ti .... 12,1s.
