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.

I see, can we expect a fix for this? We haven't heard anything for the last 2 or 3 builds and now we're on RC1 and still no mentions about it.

Thx Tom!

I'm very intersted in this as I will be buying/using a M2 MBP when they come out. But for clarity - as we assuming there is a fix needed at the Corona end. Or is there a issue at the Apple end?

Are any of the testers on this thread also using a comparable CPU engine that they could also check? Is there also a dropoff using the new Redshift CPU mode for example? Or Vray CPU? (I think these are silicon enabled now?)

Ha - don’t even consider comparing RS CPU - it’s terrible on everything - very very early days!

Just bought a new M1 MAX MacBook 16 and I have same problem, when it is 'Automatic' or 'High Power' mode selected it drops to 60-70% CPU load, while selecting 'Low Power' it goes to 80-88%. Can we expect a fix sometime soon? Also, on intel, CPU load was close to 95-97%, so even with 'Low Power' we ain't getting the best performance.

Thank you!

Posting in the one place (https://forum.corona-renderer.com/index.php?topic=38220 ) is sufficient, and better, as it keeps all messages in one place making it easier to gather the info for the team here, and easier for them to reply and ask questions.

First of all, I would like to thank the developers and the corona team because thanks to this rendering engine my work is easier and the results are very popular in my infoarchitecture area. I am a mac user, and I have renewed my equipment. I currently have the latest iMac i9 128GB that apple makes with an intel processor... it works great, I've had it for two years and both cinema 4d and corona work perfectly. I have acquired a mac Studio M1 ultra and it is incredible how cinema 4d, photoshop, illustrator works... a performance improvement is very noticeable when it comes to processing, saving, executing files and plugins. Cinema 4d moves wonderfully, everything is much more fluid. When rendering with corona I only see a slight speed around 10%-15% faster than the mac Studio M1 Ultra compared to the latest model iMac i9. However, Cinebench and Geekbench benchmarks show that the mac Studio is almost twice as powerful as the iMac i9. When I render with corona, that difference is not seen, but when I render with the native cinema engine, yes. I have selected a movie scene and I have rendered it with the iMac and with the mac Studio. The iMac returns a time of 8min-48sec and the mac Studio a time of 4min-56sec. I have a lot of trust in the Corona team and you are the ones who have more information than us. We do not question your work, quite the contrary, we appreciate all the news and corona operation. I just want to add that after several tests I have the feeling that the optimization so that Corona is native in Apple Silicon processors is not being able to take advantage of all the performance of these processors. I can guarantee you that these processors are wonderful because I have 3 different computers with apple silicon and both in 3d and in graphic design I have noticed a great performance improvement in the software I use. I just want to ask you to give this topic one more review and tell us how we can help. Possibly we have to talk to Apple to help us all, because there is some concept of this transition that we are forgetting. I am going to continue using corona because I feel very comfortable with the render engine and cinema 4d, I also feel more comfortable on my mac computers than on windows. My plans are to acquire the third corona license because I want to expand the workforce, but what would make me happier is that this issue be studied again in case there is the possibility of improving the performance of corona render when rendering and taking advantage of all the power of apple silicon. Thank you very much for everything and best regards.

At the end of the day a 10core iMac (20 threads) i9 has much higher speed base clocks than the 20 core Ultra - so there I would expect the i9 to win in certain tasks - and also the Intel Embree rendering libraries that had to be converted to work on Apple Silicon are no doubt still in their early stages of optimisation - so I think there are still things going on/ being developed.

I would like to add that I am trying to pass this matter on to the apple developers to see if they can provide some help on this issue.

Thanks for your comment. The way you explain it, I understand it very well and what you say makes a lot of sense. But... why when I run the cinebench test on multicore is the mac Studio almost twice as fast as the iMac i9? Shouldn't it be logical that something similar would happen with a crown? Is it possible that when those libraries are ported to apple silicon, Corona will return results that are more similar to those of the native cinema 4d engine? I'm just trying to help and see what limits can be reached with these processors and this rendering engine.

I agree on the Cinebench - that doesn't make a lot of sense!

According to Embree on its website, it says that both cinema 4d and corona use the Intel® Embree library. It seems that previous versions were already prepared for apple silicon. There is a new version, but I don't understand if it has optimizations for apple. Do you think that this is where the optimization can be to improve something? If so, I can't know, I still don't understand the results I get with the native render of cinema 4d. This is the point that makes me doubt that we can have better rendering times on apple silicon. Thank you so much.

Could it be the overheating issue as reported in https://forum.corona-renderer.com/index.php?topic=38220.0 ?

It's a long thread, but basically some Apple machines are not able to keep themselves cool under continuous full load. Yes, Corona can put things under "more load" than other software even if the crude high level monitoring says "100% usage" for Corona and the other software, not every 100% is created equal. After some minutes of rendering they can throttle themselves due to the heat. This can be avoided using low power mode, depending on how long the render is and how long before the machine throttles; that is, does "full speed for X minutes + throttled for Y minutes" give better times than "lower power mode for Z minutes" - the longer the "Y minutes" the more likely the low power mode option is best.

The main overheating "issue" shouldn't be a thing on the Studio as much as on the laptops - but who knows what "cleverness" Apple have put in there.

Short message regarding slow speeds on the New M-Macs.

I think that many people are forgetting that Corona Renderer is a CPU-based renderer not a GPU renderer. It's all about the machine's CPU performance and the number of cores. I am still using the Mac Pro Desktop 2013 (trashcan). It has 12 cores CPU and I honestly do not see the benefit of buying a new M1 or even M2 if Corona renderer is my end-game.

My wife uses a fully spect M1 MacBook Pro, 16". I did a hands-on test using everyday workflows and I am extremely glad I did not buy the M1. It has exactly the same speed as my trashcan, if not slower due to its 10 cores CPU vs my 12 Cores CPU. As mentioned earlier this is purely a CPU test.

On the other hand, if you are rendering in Redshift or even Arnold, my trashcan is dead in the water. I could not believe the speed in which the M1, 16" mac performs the same scene, literally 3-4 times faster! This is a massive improvement. Having said that, I am going to wait it out to see what Apple has in mind with the 3nm chips expected in Oct.

Hope this helps!

Have a lovely Sunday everyone!

@Chules - just wondering - you haven't accidentally limited the number of cores on the i9 Cinebench in the preferences have you? (Something I've done before!)
