What is Low Framerate Compensation?
AMD’s Radeon Software Crimson Edition brought a bunch of improvements in graphics performance for AMD graphics card users in a variety of ways.
Amongst these improvements was the much-anticipated frame doubling feature called Low Framerate Compensation (LFC).
To be clear this is not the first time this type of technology has been released as NVIDIA’s G-Sync has already had the feature present since its launch.
This was possible because of the embedded hardware module that comes with every G-Sync monitor.
Since AMD’s FreeSync does not have its own module the company has resorted to using software to implement this function.
Previously when a game was played with V-Sync on and the frame rate fell below the refresh rate the monitor wouldn’t have screen tearing, but it would still suffer from motion judder.
Now with Low Framerate Compensation the judder is eliminated and the motion is smooth.
Through Low Framerate Compensation whenever a game’s frame rate falls under the minimum refresh rate then the graphics card output and refresh rate will automatically be adjusted in order to stop screen tearing and motion juddering.
How is Low Framerate Compensation enabled?
This feature should be automatically enabled if your Radeon software is up-to-date… that is with a small caveat of course – your monitor supports it.
Low Framerate Compensation only works on FreeSync monitors in which the maximum refresh rate is at least 2.5 times greater than its minimum refresh rate. For example, if you’ve got a newer FreeSync monitor with a 40Hz to 144Hz range then you are good to go otherwise you’ll have to sit this one out.
No amount of tinkering in the Radeon settings will help since your monitor either supports it or doesn’t.
With the new FreeSync 2 certification process, every monitor attempting to pass has to support Low Framerate Compensation so if you see a monitor that’s marketed as having FreeSync 2 then you know it has Low Framerate Compensation support as well.
