How do you tell if Freesync is working????


Asus Crosshair VI with May 2018 bios

1700 at default settings

32GB  2666MHz

Vega 64 - I've tried drivers 18.7.1, 18.5.1 and 17.12.2.

Acer XR382CQK

Windows 10 pro 64bit


First, World of Tanks and World of Warships seemed to be stuttering and screen brightness flickered, and I could have sworn there was screen tearing so I decided to investigate further. I installed DOOM, and even though it seems smooth, I could see screen tearing with ANY setting (couldn't notice screen brightness flickering). I downloaded older drivers, even back to 17.12.2 as I saw a thread regarding what solved flickering for someone.  17.12.2 seems to have helped solve flickering in World of Tanks and World of Warships. But i still see screen tearing.   So, I installed Skyrim and Wolfenstein.   Skyrim is hard to tell of any screen tearing, but seemed to be BUTTER-SMOOTH only ONE TIME. Now some stutters!?!?!?!   Wolfenstein is nauseating while playing due to the screen tearing.  Is it just the games that don't work with Freesync?


However, AMD's Windmill is insanely choppy. I have tried AMD driver VSYNC, ehanced sync, Freesync on/off, frame limiter, etc.   NOTHING will make this demo work.  I even switched out monitors and tried the 34" version of the Acer (XR341CK) but still no go.


I could have SWORN I saw this Windmill Demo work for 10-15 second once, but restarting the demo, still won't seem smooth.  I've done DDU, and didn't help. I did a full REFRESH, didn't help.  FORMATTED and reinstalled Windows 10, still no help.


Things I've tried

-Windows 10 full reinstall

-Different driver versions

-FRTC changes

-CHILL on/off

-Freesync (driver) on/off

-Disabled Windows 10 xbox game recording stuff

-Double check 75Hz refresh

-Installed Acer's monitor drivers

-Disabled CHROME'S hardware acceleration


Thing's I've yet to try:

-bought a new DisplayPort cable (8Kx60Hz display port 1.4 certified)

-disabling AMD services one-by-one

-uninstalling STEAM

-disabling any service one-by-one.


I'm an avid fan of AMD, but this is starting to drive me crazy.  Is Freesync working? I can't tell with any game yet.  Whats most frustrating is I SWORE I could see the Windmill demo work and was awesomely smooth, and Skyrim was smooth as butter....BUT ONLY ONCE!


Do I need to try a whole different computer platform (intel?) ? Go to Windows 7?  Shake a magic stick?  Seems gaming on a samsung 22" 60Hz IP with a nvidia GTX 960 was a lot more smooth than a Vega 64 on a freesync high-end 38" 75Hz monitor.  I feel like i'm going crazy........
