iMac M1 16Gb, C4D R25 Native+Corona v8 daily Native. When rendering the cores do not work at 100%. High performance cores and efficiency cores run at 50-60% and the initial pass is very slow. Interactive render does force higher core usage, though not 100%. This will have a solution in the final version? Usage is very stable and cinema, corona and interactive render works much faster than on my iMac i9 (2020)+AMD Radeon Pro 5700 XT 16 GB.
Excellent work, you have created a very powerful tool.
