Posted this over on the Redshift forums and it appears that Deadline doesn’t currently support GPU affinity when doing a USD Render. Redshift as this attribute redshift:global:RS_gpuX_enable that Deadline never seems to configure. In my case I’m writing the USD out of Houdini 18.5, but it’s likely an issue with all DCC’s.
Everything works as expected when rendering with a traditional Redshift ROP, so this seems specific to USD. Can we request this feature?
