Many people already made a thread about that, but most of them are pretty old now. So: Why is there an flickering on my screen while playing games. I disabled V-Sync, i got the newest drivers and ReLive is ON.
Now, when i open a game, there is this flickering. When i TAB+ALT out and disable FreeSync, everything works just fine.
My PC Specs:
AMD Ryzen 7 1700 3.00 Ghz (3.70 Ghz)
AMD RX Vega 56 8GB by Sapphire
Gigabyte Aorus GA-AX370-Gaming 5
16GB DDR4 Ram by Corsair
2560x1440@144Hz 27' Monitor connected with DisplayPort
Windows 10 Home (Fall Creators Update)
EDIT: This guy describes my problem pretty well: Brightness flickering when freesync is ON in multiple games (worse since last driver update)
The thread you linked no longer exist OR i have been locked out of that thread in some way since it says im not authorized.
Well, i have the same problem but it seems Adrenalin 17.12.2 drivers mitigate the problem a lot.
Give it a try.
EDIT: I can access the thread again
