Blender Rigid Body Simulation Low CPU Usage on Ryzen 9 5900X

Support Particles and Physics Simulations

I’m running rigid body simulations in Blender on a Windows 11 machine with an AMD Ryzen 9 5900X 12-Core Processor and 32GB of RAM. However, I’m noticing that the CPU utilization in Task Manager is only around 15%.

Any help or suggestions would be greatly appreciated!

Blender version:4.1
Operating System: Windows 11
CPU: AMD Ryzen 9 5900X 12-Core Processor
RAM: 32.0 GB

If you don’t look at statistics, but if you separate each core, you’ll see that one core is working at 100%.
The simulation of the blender doesn’t use all the cores. (I haven’t checked if this feature has been improved recently :sweat_smile:)
