Slow rendering since version 4

Hi Paride,
it seems that octane renders slower than it used to. In the video attached is a blank screen and it takes 7 seconds to render it. There are 5 x 2080TIs and 11 x Titans X pascals total 16 cards
I don't understand why it goes to only 240 m samples/s and it takes a while to get to this speed and it took 7 seconds! . I remember octane 3 would do this in a second or less with like 3000 m/s on 780TIs we used to have.

And I think GPUs are also not sued at 100%



Thanks

Hi coilbook,
I'm not a developer then I cannot respond appropriately, but SA works as 3dsMAx plugin.

Hi Paride,
can you please open octane viewport in a brand new scene and see what is your samples/s then load Octane Profile (attached) into the preset and open octane viewport again. There is a bug. After loading saved preset rendering went from 500 m/s to slowly going to 150 samples/s in the empty scene
I also attached 2 videos. After loading preset profile rendering speed drops a lot

Thanks

Thanks
Also I noticed when denoiser is enabled that's when rendering slows down by half.

Hi coilbook,
I made some test, personally I'm not sure there an issue.
Imade a new setting like your and I tested it; then I got your preset and rendered.
To finish I exportated to SA and tested it.
I had 3 same time, so all seems work well.
I will ask to developers what they think.

Paride
