Hi @adrianjuarez10
If you are using the build-in Rhino render the short answer is no - it’s a CPU render, and the GPU is not involved in the process. What you can do, though, is use the Raytraced viewmode, which is a completely different render engine, based on Blender’s Cycles render. Cycles is a GPU enabled render that will eventually (hopefully from V7) replace the current, slightly outdated, Rhino render. @nathanletwory is the brains behind the operation, and he also made a small plugin Called Rhino-render-next that lets you “replace” the current render with Cycles - See this post “Shadow does not show up in render view port when i use a rectangular light” for details. I think the plugin is mentioned about halfway downand it’s installed via the testpackagemanager command.
HTH, Jakob
