I restored windows 10 and installed the driver version 17.1.1 (fresh install, even if Win 10 auto-installs some divers I used the autoremove tool to have a clean system).
It asked me if I wanted ReLive, installed it but I can't find it in AMD Settings. I tried to purge and install all again but nothing changed.
