Hi Dr. Sassi,

thank you so much for your speedy reply and answer. You guys are doing a fantastic job!

I think my system is currently misconfigured. searched a bit on reddit and I think my SSD might be sharing bandwidth with my graphic card. CPU-Z indicates under Graphic Interface, Current Link Speed is 2.5GT/s, although Bus is PCI-Express 4.0. Max. Supported is 16.0 GT/s.

Hope to fix this issue on my side. Still not entirely sure what's wrong yet.

Good day!

My workstation is an Intel i7-14700, paired with an Nvidia Geforce RTX 4070 Super (latest studio drivers), with 32GB RAM. Windows 11, Cinema 4D 2025.1.0.

In the tutorial, the particles generated very quickly and played back smoothly, when it was set to emit at a rate of 10,000,000.

However, when I set 10,000,000, it's very sluggish during playback with my workstation. Under Project Settings / Simulation / Scene, Device is already set to GPU. It says Compute Device is "0: BusID 1 : NVIDIA GeForce RTX 4070 SUPER"

What could be going wrong here?
