After installing the latest NVidia drivers 411.70 and starting MSI Afterburner the program constantly activates the discrete NVidia graphics on my MSI laptop with NVidia Optimus (status led is constantly orange). After exiting MSI Afterburner the graphics switches back to Intel and the status led is back to white. This causes the laptop to constantly drain more power. This does not happen with NVidia drivers 399.24 and before (switching graphics works with MSI Afterburner running in the background). ????
