E-cycles vs Cycles

Hello

what is the purpose of E-cycles?
since the Cycles rendering time that comes with Blender is almost the same.

thank you

Well it is the same for you its indeed not useful.

E-Cycles has several patches from the developer website that are currently not in master and other small things from the developer that sells E-Cycles. Could be more or less and i am sure it was a lot of work but still most of the performance boost come from patches from the blender devs.

In short it shut fasten up the render times and thats basically it i think.

can you tell me if it pays to use E-cycles, at render time, compared to Cycles?

I am pretty sure in the E-Cycles thread is a comparison. I guess it even can be googled…
In my opinion its only worth it when you render a lot and that thing is also pretty pricey… In the end you have to decide.

Well look at that it works…

There are many videos and comparisons out there that prove that it’s much faster, not sure where you got that it’s almost the same.

It has a very nice integration of Light groups and a more reactive viewport in E-Cycles 2021.
It’s up to you to decide if it is worth it or not.
