After many mails from support now is silience. Nothing helps. I think I have to wait until next patch in december.There is suggestions in order from the earliest to the latest. (Maybe will be useful for someone)A)B)Please perform clean boot to see if applications running in the background are interfering with Gwent:C)Perhaps a clean installation of the latest graphics card drivers will solve the issue.At first please delete your current drivers by using the following application => http://www.guru3d.com/files-details/display-driver-uninstaller-download.html Afterwards please install the newest drivers from the website: http://www.geforce.com/drivers/ D)Please check if uninstalling GeForce Experience will help (if you have it installed). Please also make sure you won't run any apps that use Overlay e.g. Discord when running Gwent._________________________________________________________________________________________________I did everything correct but nothing helps.
