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.
