HI guys,
I noticed that the latest release 10 daily build (Daily Build 2023-04-03) is slower than the official 9 release.
Of course is not stable so I'm expecting this but in some scenes it's like 2x slower (9 takes 2 minutes to render, 10 takes 3:30 minutes).
I'm attaching here a test comparison in a simple scene with only 1 hdri.
Is there any workaround or is the latest 10 version still buggy?
I'm in love with the shaders in the corona lights so I really want to use the latest daily build lol

Hi guys,
I've just tried the latest build (2023-05-17) and still is way slower than the official build.
Are the developers aware of this?
Thank you!

Hi there, could you please send us this exact scene so we can test it as well? Please use the "save project with assets" option to ensure everything is linked to the scene. Thanks in advance :)

Hi Bengamin.
The problem is not related to this specific scene, the problem happens in any single scene I work on.
Is it a hardware problem? Maybe is windows 10?

Hi there,
Did you try testing the performance using the same C4D version?
I can see you were using C4D R23 and 2023.
What happens using the same version? Does the issue persists?
Looking forward to hearing from you.
Kind regards.

Hi Benjamin,
Yes I tried on the same version and got the same problem. I did the test on 2 different versions because it was less time consuming for me.
But yeah, the problem is still there.

Based on your example given, I'm only seeing a difference 12 seconds between the two. You mentioned the V9 was twice as fast, can you please share the scene where this is happening? I also ran a few tests, 1 identical to yours and another that was more complex (interior scene) and I also only got a few seconds difference between the 2. Thanks in advance!

Hi Bengamin,
here I'm attaching my latest test, done with the same c4d version (2023), same scene settings, no other process running in background. Lighting done using hdri, some corona decals here and there, mix of cad data and poly models, dispalcement and so on.
As you can see v10 is 27 seconds slower, in this scene the v9 is about 10% faster, that is a lot for me.
If you apply this to a 20 seconds animation (let's say 500 frames, 2 minutes render per frame) it would take almost 1 hour and 30 minutes more to render on v10.

I will log this for further investigation.

Hi guys, I have some updates.
I've just tested the latest daily 10 build (05-30-2023) and it is still slower than version 9.
This time I'm testing using Intel i9 13900k, 64gb ram ddr5 6000mhz, windows 11.
No process running in background.
I've used the same scene I rendered in previous posts but I can guarantee that the problem is there in any scene.
Scene parsing and denoising times are always the same, render times are different tho.
