Okay, this is strange, as well... all three GPUs are maxing out at only 80% usage... I have them all set to use the max 120% power target. How do I increase that to get them all to 100% usage?

You can't do that manually. Renderer use them as much as possible. It depends to calculation requirement ...

try unchecking "low priority" in your devices settings in c4d.

None of them have priorities set (low or high)... none of them are checked

to give You propper reply. based n numbers & speeds..

gk110 based cards like 780Tis or Titan Blacks could score around ~110 in OctaneBench
1080s for now score ~140 & in some cases 160.. so 3x 140+ is around the same as 4x 110..

Consider the fact You're comparing High end card from one generation ...

hi, Edensoto,

Here is a thing, & I'll try to explain what happened =) the reason OctaneBench has different scenes.. is because You can not judge cards performance based on one specific kernel or one specific scene. As far as I understand cards from different architectures behave differently..on ...

Just made a similar post myself:

viewtopic.php?f=30&t=58072

I was expecting a much bigger boost coming from 4 x 780 Ti's to 3 x 1080 SC's and my test render results were almost identical... as in... no performance increase whatsoever.

Have an ASUS Z9PE-D8 WS and previously had 4 x 780 Ti GPUs on it, just upgraded to 3 x 1080 SC GPUs and before swapping them out, I made a test scene for myself... on the 780 Ti's, it rendered in 10:00 min... with the three 1080 SC's, it rendered in 10:04. Even tried keeping one of the 780 Ti's in ...

Virtual toast! You are amazing. Thank you again.

Make a color tranform with python
linear -> srgb
or
srgb -> linear
don't forget to multipy octane values by 255.0 for 8bit color outputs

THANK YOU! I will give that a shot, but given ...

Having a hard time wrapping my head around an issue... what I'm trying to do is convert an Octane Diffuse channel's Color RGB values to C4D's RGB value with no success. My closest attempt was feeding the Octane's RGB value (0 to 1) through a Range Mapper using a min/max of 0 and 255 to Octane's 0 to ...
