I just picked up and installed a RTX 2080 Ti. The current OctaneBench does not support the GPU yet, whereas Octane in Modo and LW does.
I'll perform some renderings of the example scenes and write some numbers..
Modo & LightWave 3D| Win 10 x64 | RTX 2080 Ti | Threadripper 2920x | 128GB
A really great thanks for sharing these very interesting results
It is a pity you do not have a 1080 Ti.
I will try to order two RTX 2080 Ti for a render slave.
