Why does FreeSync only work in the Windmill Demo?

I am using an LG 34UM68-P monitor tested with both an r9 290 and an rx 480. I have free sync enabled and I cannot tell it making a difference in any game besides the AMD windmill demo. When I play any other game I get tearing as if free sync is not activated, but in the demo I can clearly see the difference free sync makes. Tearing is gone and there's no sync stuttering. I am honestly beyond confused and many people on the internet have sent me through the same steps to try and fix the issue but nothing has worked.

I am using an RX 480 with the driver 16.7.2 with free sync enabled in the radeon settings along with a free sync monitor that has free sync enabled in the monitor's settings.

I am using a display port cable.

I am playing in fullscreen.

I am meeting EVERY requirement to get free sync working but it will ONLY work in the windmill demo. I have reinstalled drivers with DDU, I have tried this on TWO different systems and the same thing happens. Free sync works only in the windmill demo.

Can anyone shed some light on this issue? Could my monitor literally be defective at this point? I have tried limiting my framerate below the monitor's refresh rate of 75z. I have enabled v-sync alongside free sync, but.. Free sync can't possibly require v-sync to work properly. I can clearly see it working in the windmill demo with no tearing or stuttering.

Pls help

The freesync range of that monitor is only 48 - 75 or 40 - 70 depending on which version you got.  Freesync would only work between those framerates.  If you use the CRU utility you can maybe be able to set it to 30 - 70 instead so it would be likely to work more often.  You shouldn't need to use Vsync.

Its not working at any framerate and the freesync range is 40 to 75hz. Even when I am in the range. Its as if its not even UNLESS im in the demo.

Have you got frame pacing enabled in the global profile? If not then you need to enable it.  Have you also checked the monitor OSD to see what refreshrate it is set to? (if it provides that info)  Also you need to be using the Radeon Settings frame limiter not using RTSS to limit them.

Themonitor's refresh rate shows that its 75hz in the settings, matching what I have also set it to in the monitor's settings in windows as well. In other words its displaying 75fps. I've also been using frame rate target control in the radeon settings to limit the frame rate from going above the monitor's refresh rate.

I don't see any frame pacing option available in the global settings. Am I looking in the wrong location? I'm at gaming>global graphics.

Check out this document and ensure you have everything setup correctly and remember, FreeSync only works in exclusive fullscreen mode.

Re: Why does FreeSync only work in the Windmill Demo?

I have read through this post and have the set-up as follows:

LG 34UM68-P with FreeSync enabled

I have a Display port 1.2 cable linking the monitor to the card

I am using an AMD r7 265 graphics card using 16.10.1 software

AMD Radeon Settings is telling me that FreeSync is not supported - why?

R7 265 is a rebranded 7850, neither of which have the necessary hardware to support FreeSync.

Oh, that is a bit of a cheeky thing to do but thanks for the speedy reply
