#Using optimus-manager - switches graphics with a single command (logout and login required to take effect).#Using PRIME render offload - official method supported by NVIDIA.Using both (use NVIDIA GPU when needed and keep it powered off to save power):.This utilizes the same underlying process as the optimus-manager and nvidia-xrun options, it should be utilized for troubleshooting and verifying general functionality, before opting for one of the more automated approaches. #Use NVIDIA graphics only - gives more performance than integrated graphics, but drains more battery (which is not welcome for mobile devices).#Use integrated graphics only - saves power, because NVIDIA GPU will be completely powered off.
