Hello,
When I open octane viewport and render with 3080ti i get around 24 samples/sec with 4090 just 3.

4090 is display card but still why is so slow?

The PC has 3 3080 tis and 1 4090 as the main card

Thanks

Hi coilbook,
The main GPU handles peripherals and anything that relies on the graphics card, but it looks like your rig is pulling pretty heavily on the 4090. Have you tried running separate Octanebench tests on each GPU to see how they perform individually just make sure to close any running applications first (including your web browser)?

Hi Paride,

here are the results. I think octane 2023.1 has bugs. I'll try a newer version

This might be the reason RTX on does nothing or actually makes rendering by 10-20 sec slower.
