I own 2 Vega 64 and I am experiencing lots of issues with the Adrenalin drivers.
I got lot's of flickering DisplayPort and FreeSync doesn't appear to work at all.
Freesync not good working, Virtual Super Resolution not supported.
Version: Adrenalin 19.1.2
Monitor: Samsung 49" CHG90 QLED Gaming Monitor - FreeSync
Graphics Cards: 2 Asus RX Vega 64 - Crossfire
Resolution = 3840 x 1080
Processor: AMD Ryzen Threadripper 1950X
RAM: 48 GB, CL 14
AMD, this issue has been around since almost 2 year and 30 different driver versions now. There has to be a fix for that.
We all spend a decent amount of money on your GPUs and again a lot of money on FreeSync monitors. So please don't let us down.
