When testing the results of the Raytraced display, I get top half of viewport partially rendered and bottom half fully rendered. Suggestions?

Please post the results of the Rhino commands _SystemInfo and RhinoCycles_ListDevices

You might want to start out with updating the drivers.

Also make sure you don’t run your cards in SLI (software or hardware), since that isn’t supported.

If that doesn’t make things work try disabling third-party plug-ins.

Let me know how things work out.
