The fact that other software can't run the CPU to its full capacity over an extended period.
Sorry Tom, but all Corona Team continue to replay that. I understand that every software developer loves it's creatures...and we love Corona Render too...but please could we try to analyse the fact that Cinema4D Cinebench or Cinema4D standard/physical rendering engine can handle the CPU up to 99% for hours without any overhead, without any CPU throttle and without any ISSUE on Apple Silicon Processor...?
Nejc Kilar is the only one said interesting things about the "different" part of the CPU used for calculations...maybe Cinema4D rendering engine takes part of the CPU for calculation that Corona and Vray don't....it's interesting. I don't know deeply how the pure calculation works...but what I know that Cinema4D push the CPU at it's best, Corona it doesn't...Science is a fact and numbers say that.
Anyway, I wrote many time about that Corona Render "sometimes" reach the 98% of the CPU...and after some loop renders on the same scene, continuous works or long period or "I don't know why", it falls below 800%...sometimes 750% of a total of 1000% of 10 core Apple silicon CPU. The Cinema4D rendering engine stay up to 990% of the CPU, this make the CPU Hot, not as my second iMac with Intel 10K generation processor that become very hot, but the CPU never falls below 990%.
I tested internally the behaviour of:
iMac i9 10K
Apple Silicon M1 Max.
We have the same Cinebench numbers: around 14.000 CB. So when I try a complex scene, my M1 Max and my iMac i9 renders with the same timing...M1 Max is a little bit speedy.. and stay cold..the i9 seems a phon and drive me crazy :)
I tried with a complex Corona Render scene and at first passes my M1 Max outperformed the iMac i9. But after sometime my M1 has fails with a 20-25% of processors percentage unused.
It seems a throttle issue, but it doesn't...
I want to repeat my question: way does Cinema4D rendering engine use 98% of the processor for hours? How different are the mathematical instructions sent to the CPU by Cinema4D rendering engine and Corona Render? Do you think is a good idea to try a Stand Alone Rendering without pass through plugin Ecosystem? Maybe Cinema4D creates a bottleneck?
This pictures from me are absolutely clear.
PS: I don't tested the low power on or low power off...I work with automatic power...my corona issues come up with any settings.
