Are the two computers identical hardware? The speed of the PCIe bus plays a role in GPU computing. Review your motherboard's specs.

I might guess you'd have to Unpack the alembic before you can assign materials. Otherwise, you'll just be adding attributes to the points representing the packed parts, and not the actual surface.

Try dropping down an Unpack node right after the file or alembic node.

The way I understand it is that VEX wrangles running over points and primitives are multi-threaded. When you run a VEX wrangle in detail mode, it's running single core.

What first comes to mind is duplicate faces. I would critically inspect the mesh geometry.

Check out this link on applying drag based on distance. You may be able to modify it for your use.

You may want to re-tool your network to work with TOPs for that.

That's the particlefluidsurface node's function. It makes a mesh. Delete it from your network to avoid mesh creation.

That doesn't happen using H20.5. Try upgrading from 19.5 to the latest version.

Instead of deleting the path attribute, why not rename it to "my_PATH" and see if that works. The @path attribute will be gone so import should still work, but you'll be able to reference my_PATH to construct a material or ID.

Without seeing a hip file, I'd guess you ran out of physical ram or your overclock is set too agressive. Try rendering to disk, not MPlay. It holds every frame it rendered in physical ram and can build up over time.

MPlay is essentially a wrapped OpenGL ROP. You may want to focus there instead.

Unfortunately, the setup is not simple. Here's about as basic as you can get. Unpacked RBDs hang out inside a flip volume, being affected by it.

Sounds like a redshift problem. Can you test it using Karma? Does Karma use your eGPU?

If you have any nodes locked with geometry, that could be what is slowing things down. Is your HIP file size huge?
