I finally solve the problem ! Installed last GPU driver and changing the way I go offline in Hitman 3. Unplugging the ethernet cable was not a good idea I think...
Thanks for your kindness and patience with a retarded user, guys !
Glad to hear you fixed it and thanks for letting us know how!
How do you actually go offline in HITMAN 3 without disconnecting physically?
As you wrote in the other thread, the simplest option is to not accept the privacy policy.
