My System consists of a 390X, 8 GB of ram, Windows 10 x64 creators update, crimson relive 17.5.1. Ever since I updated to creators edition, I can't change my display resolution in Windows settings after some reboots (happens randomly). The options are then just greyed out. This also leads to some games not starting at all. Some run in windowed mode instead. I tried reinstalling (different) drivers, but with no success.
