I have tried to verify that feesync is working with my monitor, so I downloaded Nvidia pendulum demo, because AMD does not officially provide any such a demo and with Nvidia pendulum demo I see tearing even if I enable freesync.
Does anybody know how to make freesync work and how to test it?
If it's enabled in your monitor's OSD, and enabled in Radeon Settings, then it's working.
It is enabled in monitor and also in Radeon Settings, but it is not working. There is massive tearing in test application - there is simple vertical bar that is traveling left to right and freesync should make this movement smooth but is it not, there is massive tearing.
Try testing some games instead.
I made incorrect testing having incorrect assumptions. I have not studied freesync details, I believed that it somehow works but it does not. My monitor has freesync range only 55-75Hz, so freesync is pretty pointless with my monitor.
Nvidia pendulum demo application works perfectly and I was able to verify freesync works. I also created custom monitor resolution ans was able to override freesync range to 35-75Hz.
I will however not use freesync or any monitor overclocks due to ailing Radeon drivers, I will use everything stock to avoid crashes and system hangs.
