Freesync solution for screen tearing in monitor


What is project FreeSync?

Computer monitors usually refresh at the rate of 60 frames per second.As the contents like video having constant frame rate of 23.976 frames per second,so there is a sync between the video and monitor.But in games,there is never sync in monitor due to variable frame rates,which causes screen tearing. Freesync is the solution. Let’s see how it differs from traditional method to avoid screen tearing ?

In traditional way,problem in games were solved by vertical Synchronization(v-sync).when the v-sync is ON,the computer delivers the frame rate at the monitor’s refresh rate exactly.the content and monitor were sync and the problem were gone.

                                               But when the game is in action,the monitor may not receive new  frame from the GPU at it’s refresh cycle,so monitor will display current frame at second time.And here the tear will be seen at higher frame rates,that will result into lag,which will still annoy most of the users.

                                                 But AMD has found solution for screen tearing by allowing the monitors frame rate to vary(eg:10-60 times per second) and let the refresh rates controlled by and synchronized to the Graphic cards.This was proposed by AMD to VESA(a standard body for standardizing display specifications) and this technology was accepted by VESA and integerated  into Display port 1.2a specification as “DisplayPort Adaptive-sync”.monitors which will feature Adaptive sync will refresh at the dynamic rates.To utilize the features of such a monitor ,you need a graphic card and a graphics driver.

It is same as that of Nvidia’s G-sync technology, but monitor vendors are mostly using AMD Freesync technology for stutter-free display.

                project freesync is AMD’s name for the solution: a compatible radeon Graphics card,an AMD catalyst driver and an Adaptive-sync aware display for reducing input latency,abolishing tearing and to eliminate sluttering.
