I've recently upgraded to a Sapphire Nitro+ 5700XT and dual Acer Nitro VG271UPbmiipx 144Hz FreeSync enabled monitors and I'm having a strange issue regarding FreeSync and black screen stuttering, although seemingly not uncommon I've yet to find a solution which works for me.
Whenever opening a game from a cold boot (by cold boot I mean full power off and left off for a few minutes) the black screen stuttering will occur with any interaction (occurs with CS:GO and WoW). If I turn FreeSync off, the problem goes away. Also this did not seem to occur when the monitors were set to 60Hz.
The problem is always resolved on a reboot (reloading GFX drivers does not seem to work). But this solution is annoying at best... and particularly after my first PC component upgrade in quite a while
I've tried a number of v19 and v20 Radeon drivers and the problem persists (with and without the bloated software). DDU''d several times both nvidia and AMD. I've also installed the monitor drivers from the Acer website.
Some more details:
Windows 10 64bit
Both monitors connected via HDMI (issue occurs on both monitors)
ASUS P8Z68-V PRO mobo with i7-2600K (Yes old, this was step one of upgrading my PC whilst improving my working from home experience..)
850W Corsair PSU
Does anyone have any suggestions? Many thanks
