I had the opportunity to test E-Cycles on a freshly packed scene, to have a margin of comparison.
I must admit that the results are amazing.
Here the Thread.
The main scene, calculated at 2500 samples, 2400px, previously used almost 3 hours for the calculation.
With E-Cycles we are at 1h 20 … Less than half.
Same with the other scenes.
Before we were on 2h and over, now with E-Cycles on the 16 minutes at the end of the calculation (2400px, 2000 samples).
Obviously in terms of performance I believe the data speak for themselves.
On 8 images, 2h one I lost a day of calculation.
With E-Cycles, in just over 2 hours I solved everything.
Surely, by making some improvements to the settings, I could gain more time.
