Hi Aoktar,

With a new scene, cube primitive, panning left right continuously I get 70-120 in the C4D viewport.

With Octane IPR running, 7-14.

The RS IPR in comparison gets 70-100.

This is on a 5,1 with 2x 1080ti
10.12.6
Nvidia 378.05.05.25f01
CUDA 387.178
R20

I can try some other systems ...

Hm. I just loaded up the 4.01 plugin update, no change.

Has this been addressed yet?

I was testing Octane out on two systems, and was immediately put off by how bad C4D lagged with the live viewer running. Even a new scene with a cube in it is choppy. I tried changing priorities and enabled cards, no change. Standalone runs fine.

One system is an iMac ...

Hello there

How does one go about having an image as a backdrop?

I checked out the example demo scene 'background_and_matte' which was promising, but reflections/refractions do not show the background object material. They just render black. What am I doing wrong?

Cheers
