.... nVidia have just released a new driver v364.72 and the Geforce Experience is updated to v2.11.2.46 with the new driver. CyberLink have carried out a quick test and found the PowerDirector crash issues caused by Geforce Experience seems not happen with the new Geforce Experience version. CyberLink are implementing more testing and confirming with nVidia.
... the suggestion is for members who are still expecting to use Geforce Experience, to update to the new version.
