Oil Paint/openCL is grayed out and Nvidia control panel doesnt show preferred graphics processor

So Im trying to enable oil paint to run some actions but it's grayed out. I found the basic fix to enable it but it seems Im missing a key aspect to get it working, to enable the feature in nvidia control panel to select the preferred graphics processor for photoshop in order to get openCl working in photoshop. Has anyone found a work around to get that working? Any help would be great thanks
