Title: Corona performance affected by VFB zoom level
Post by: Fluss on 2017-05-09, 14:02:32
I've just noticed that the zoom level in the VFB drastically affect rendering performance. When i look my render at 1:1, I get about 6 800 000 rays/s and when I set the zoom level to 1:32, I get about 7 800 000 rays/s which is a hudge gap imho. Does anybody else noticed that ? I have not tested that behavior on other scene but if it does behave like that on every renders, don't forget to zoom all the way out when you're rendering.

I just tried and... yes, the numbers rise, seems to be around 10% in my case.

hi,
what CPU do you have, and what refresh rate do you have set up in system wide settings?

That's interesting. Curious to see if render will finish faster also? Could be nice boost mode :]

I'm on a dual xeon e5-2683 v3 (total 28 cores/56 threads) - 64Gb RAM.
Refresh rate on default - 1000ms.

Thanks for moving the subject.

After further testing, it seems to be inconsistant, but overall, I experienced a performance drop from 10% to 25% in some case.
