GPU Pyro Super Slow


Recommended Posts

Hi there!


I was experimenting with the new NanoVDB stuff in 18.5-- following this tutorial: 

I've realized that my machine doesn't seem to solve the simulation anywhere near real-time, maybe a few seconds per frame-- even though I'm running on a brand new RTX 3080 Ti.

Is there some weird driver thing I need to fix-- or anyone else had issues like this? "Minimal OpenCL Solve" is checked-- but my GPU hovers around 5% usage the whole time.
