I never looked at that tab. It still had the original install defaults, so I changed them.
I did read this page:
but it is not clear on how to optimize video card render times without actually setting each of the parameters to see if you like that quality.
In summary, using the same settings except for bucket size I am surprised that my fancy new video card is not that much faster than my CPU.
3090 GPU best times: 122.5 sec
i9-10980xe best time 218 sec.
each image look to me indistinguishable in quality, and GPU is not even 2 X faster.
So why in Blender 2.79, using the same Cycles engines, do I get at least 3 to 6 times faster render times? Even more so in Blender 3.x
This is why I consider this to be a technical question.
As you can see not a lot of room for extra fans. I have to keep the side open, back is off because I am doing some rewiring. The drive that gets hot has the silver heatsink just below video card.
Yes I am sucker for drive space. Three 6TB HDDs and 3 assorted SSDs in addition. Knowing that my HDD will still have data after 20 years, as opposed to bit rot on SSD after 5 years unpowered, means I will still use them. Also I use DVD and bluray disk for archival storage, that's why I bought this case. Had to shoehorn my CPU cooler as you can see. Tie-wrap holds up the video card to keep it from sagging.
