Hi all,
When I render images on my iMac (2017 27" 5K model, i7 4.2GHz, 64GB RAM, AMD Radeon Pro 580) with Twilight Render Pro in SketchUp Make 2017 I noticed that after a while, the fans start slowing down to almost silent... I always thought that was normal, but when checking the activity monitor I noticed that the processor usage drops to +/- 50% usage instead of +/- 100% after a couple of minutes? Only when I interact again with SketchUp, it spools back to 100%.
In the render settings I specify that it has to use all 8 cores. Using render setting 09.
Below two screenshots.
One of activity monitor after a couple of minutes not interacting with SketchUp.
One of activity monitor when I reinteract with SketchUp. Notice the sudden spike in CPU usage...
Anybody else having this issue?

There may be tools that work on Mac for monitoring CPU temps second-by-second (CPU-Z is commonly used for this purpose in the world of Windows machines.)
If you intend to use the machine for production rendering you will probably need to greatly increase the cooling capability of the machine - either by adding fans, using an after-market cooler. This is why Windows machines are more common in this space because they can be modified more easily.

Macs are notoriously bad for 3D rendering, an issue long-known among 3D professionals.Fletch wrote: ↑Wed Feb 05, 2020 11:35 pm Unfortunately, it's probably a "thermals" issue common to Macs. It's essentially throttling itself to control heat. Definitely start by getting a good cooling pad under the machine.
