Hi!
I recently noticed some bugs with my most recent PC station while using Cinema4D R19 (or R20) with Octane 2020. It's about the render time/performance..
The specs for that one are :
- 2x RTX2080Ti 11Gb
- Intel Core i9-9900KF 3.60 GHz
- 64 Gb RAM
- Windows 10 64 Bits
And I have another station that has :
- 1x GTX1080TI 11Gb + 1X GTX1080 6Gb
- Intel Core i7-7700K 4.20 GHz
- 32 Gb RAM
- Windows 10 64 Bits
If I use the Octane Benchmark 2020, I got a 701.37 score on the RTX's and 334.5 for the GTX's, so everything seems fine here.
But whatever scene I used on Cinema4D with the last version of the plugin, with the EXACT same scene, same C4D version and same render settings.. My RTX's station is rendering every frame almost 2 times slower than my GTX's station...
In fact, it seems that the RTX's cards are just not running full speed when using C4D. During the Benchmark test, I could see a huge difference regarding the fan speed, noise etc compared to a normal Octane scene render. I really don't get it
Here is some screenshots of benchmarks and actual renders:

I've also tried several C4D scenes, same issue.. And all my drivers are updated on both stations..
Hopefully this is just tiny thing to adjust.. because it hurts to pay twice the price of a 1080Ti and gets that result...
Thanks for reading,
