Hi all,

I'm running Cinema 4D 2025.0.2 and OctaneX 2024.1-R3 on macOS Sequoia 15.1. This is running on a Mac Studio M2 Ultra with 76 GPU Cores and 128 GB RAM.

No matter the render settings in regards to priority I can't get Octane to utilize more than 50% of my GPUs. Is there any known issues like this or anyone else having the same problem?

If I render a test scene in OctaneX Standalone 2024.1 it maxes out my GPUs.

Sorry, I cannot reproduce the slowdown here, the GPU usage is 100% in both Live View and Picture Viewer, in C4D 2025.0.2 and c4doctane 2024.1-R3... but I'm working in Sonoma 14.7, not Sequoia: Have you tried with different scenes?

ciao,
Beppe

Thanks!

Did you connect both MacBook Pro to power supply during test?

Yep, Power supply on both (same results whether 'automatic' or 'high power' in system settings).

Standalone 2024.1
M3 Max (Sonoma 14.1)
M4 Max (Sequoia 15.1)

I can't get near 15s with M3 Max (which you have listed), so I'm guessing that was an earlier Standalone version?
Would be great to see M-series results replaced with the latest standalone (if you can collect them).

That said, the M4 Max feels significantly faster than M3 Max in C4D Live Viewer C4D 2024.4.1 / Studio 2024.1-R3).
So I'm pretty happy with this upgrade!

Strange results with your MacBooks :-/

My MacBook Pro M3 Max 40-Core: 15 sec
My Neu MacBook Pro M4 Max 30-Core: 12 sec

Both plugged in or on battery with same results.

Thanks davidvonbehr for confirmation on M3 Max result, and for M4 Max 30 core result!

Here is the updated chart: Happy Mac GPU rendering!

I'll have to figure out what's going on there then?

Have you installed a macOS beta update?
