RTX 3090 D-force Simulation performance?

vitomorantz

Hi there, I've recently built an RTX-3090 PC (with RYZEN 5950x CPU) and 64GB ram. The RTX 3090 is amazing and has sped up my IRAY Rendering performance by 1000 percent. But one thing I've noticed however is that when I run d-force simulations (simple cloth or hair) my system shows very little CPU utilization (max 14%) and virtually zero GPU utilisation during the simulation processing. (See attached photos that show this, as well as my render settings / DAZ preferences etc). Has anyone else experienced this when running d-force simulations with RTX 3000 series? Is there any way to get d-force simulation to utilise more of the CPU and / or GPU, as currently it seems to be using only about 14% of my CPU (at a maximum, usually closer to 7%) and virtually none of my GPU. Thanks for any advice!

dForce uses OpenCL so I would have expected it not to show in the CUDA graph - but on a quick test just now it did.
