The render results with the mac book pro M1 Max are worrying. I have been greatly disappointed. I don't know if the mac is not as powerful as we are told or that at the moment corona render is not optimized. Surprisingly other applications work amazingly on M1, much better than on Intel Mac. The cinema 4d itself on the M1 is a joy to use, much smoother than the latest intel i9 iMac. Do you know if work is being done to improve the corona performance in M1? Because I get the feeling that the M1 and M1 Max processor is very powerful, but that the crown does not take advantage of it. Thank you and greetings.

I work with a Mac Studio m1 128Gb.
I think the performance is what you expect from a 20 core CPU. The benchmarks equal those of PC's with the same amount (hyper)threads. I notice though that the kind of scene or model and how "smart" it is modeled makes a huge difference. That aplies to PC's as well I would say.
The Mac Studio with its fast read and write RAM and SSD is a joy to work with. I think if you want GPU performance on final high res renders you need a different set up.

Do you have some specific test scene that could be rendered on various CPUs so that the results could be compared? What exact kinds of results do you find worrying?

Are you able to monitor the temperature and usage of your CPU? Is it showing 100% CPU usage during rendering?

Hi, as Maru said, please provide us with your test scene files (including all necessary assets) and your hardware/software specs (OS version, CPU model, C4D version, Corona version, etc.).
You can include it here, or you can create a support ticket to include the files.
Please let us know the outcome.
Kind regards.

Yep its not magic - a 10 core CPU is just a 10 core CPU. My perfomance to is what I would expect on my M1 Max - i.e. the same if I was on a non-Hyperthreaded 10 core PC.

I guess any optimisations will have to come from the Intel Embree raytracing kernels that everybody uses? (guess)

Also, would be good if we could finally get a native M1 Benchmark tool?

I've been tracking scenes with my macbook m1 pro and I notice on the latest release vesion 8 hotfix 1 every now and then the cpu reach only 70% of it's power and it wont pass that, a fix for it is restarting the mac  but after awhile it caps at 70% again. With the latest daily it happens less frequently.

Monterey 12.4
Macbook pro M1 16"
Cinema 4d R26.107

I found the thread describing the same problem:

No mention about the performance issue on the new build??

sad

Guys news about performance? I got a MacBook Pro M1 and I have this rendering issue with hotfix 1 as well.

Hello,

Thank you for your replies.
Please consider that Macbook's cooling system could not be enough to keep the CPU working at its full all the time.
Someone already mentioned something about expected performance using a Mac Studio, which has a better cooling system compared to a MacBook.
Are you using a specific monitoring tool that shows the 70% CPU capping issue?
If so, could you please let us know the tool and the steps you followed to find out the issue?
Please be as descriptive as possible so we can try to reproduce the issue.

Can be seen just in Activity monitor. Ironically - if energy setting in system preferences is set to Low Power it squeezes out the most CPU usage - setting to High Power drops it to 600-650%.

Definitely some kind of "algorithm" going on.

Why render on Mac, Whyyy ????. Price/Power is ridiculous about Mac Computer
Go for it to RenderFarm

Philw is right.. I managed to get couple of screenshots one in low power mode and high power:

I dont believe it's temperature issue, mine never get above 80-85ish C.

All my renders are always with the mac plugged in "High power" most of the time the cpu runs full speed and out of nowhere it drops to 650 ~.

Seems like something triggers LOW/High power mode and thats when it drops.

Im on r26

hello all,

I see the new RC1 is out and no mention about the performance issue while hipower mode is on for macs M1, anyone tested this latest build ? Or any Dev could tell us if it was fixed on the latest buid'?

Thx

If it's not in the changelog (https://forum.corona-renderer.com/index.php?topic=36221.msg203964#msg203964) likely nothing changed - sometimes something can be overlooked in the changelog but that is very rare, sorry.
