Hi all
i'm curious to try my gtx1070 with flip fluids, but even though it's selected in the miscellaneous settings and i enabled opencl in the solver, the gpu doesn't seem to kick in at all. I used “hgpuinfo -c” also which doesn't show anything wrong on my video card.
Nvidia drivers 432.00.
Is there another way to enable it?

No, OpenCL only works on limited resolutions. Most vRAM is not large enough to hold a decent simulation. You may have set your FLIP resolution too “high” with a low particle separation. When this happens Houdini politely degrades to CPU calculations, instead of GPU calculations. This make OpenCL more of a “toy” to play with, rather than a production acceleration tool.
How are you monitoring your GPU usage?

I have 2x3090 and OpenCL on fluids still feels like it makes it worse than if it's on. The only time I see a benefit of it is in the pyrosolver and axiomsolver (duh!). Feels like it needs a rehaul!
