The graphics on traditional displays are typically refreshed at a predetermined rate. On the other hand, if a game requires greater frame rates that are outside of the range that was chosen, particularly during sequences with rapid motion, the monitor might not be able to keep up with the abrupt rise in frame rate. After then, the monitor will display a portion of one frame along with the beginning of the subsequent frame at the same time.
Consider the following scenario as an illustration: your game is running at a rate of 90 FPS (frames per second), while the refresh rate of your monitor is only 60Hz. This indicates that your graphics card is performing 90 updates per second, while the display is only performing 60. The result of this overlap is visuals that are fragmented, appearing almost as if there were a tear in the screen. These lines will ruin the otherwise stunning visual experience and make it difficult to actually play the game.
Stuttering in video games, sometimes known as micro-stuttering, occurs when individual frames are skipped, repeated, or frozen. This typically takes place whenever there is a delay in the input being sent from the GPU to the display. Games, particularly those with a high emphasis on visuals and a rapid speed, will have a sluggish and jerky feel to them, and players will observe pauses in the action and abrupt hiccups on the screen.
A drop in frames per second (FPS) is frequently the root cause of input lags. This occurs when the graphics processing unit (GPU) renders images at a slower pace in comparison to the monitor. V-Sync is one of the factors that might contribute to a dip in frame rates that are lower than the refresh rate of your display. This will create stuttering and input delays when playing games.

What is V-Sync?
V-Sync, which is often referred to as Vertical Sync, is the name of the original GPU technology that was designed to synchronize the frame rate of a game with the refresh rate of a monitor. This technology is present in virtually all modern graphics cards. Its primary purpose was to prevent screen tears, which inspired its creation.
When the Vertical Sync (V-Sync) feature of a display is turned on, it assists in limiting the frame rate output of the graphics card to the refresh rate of the monitor. Because of this, the monitor is able to avoid handling more frames per second (FPS) than it is capable of, which minimizes screen tearing. However, if the game's needed framerate dips below the refresh rate of the monitor, having V-Sync enabled will cause the frame rate to drop even further so that it matches the refresh rate of the monitor. This results in additional latency, which slows down performance and increases the amount of time it takes for inputs.
Because of this issue, a solution known as Adaptive Sync was developed to eliminate screen tearing while also concurrently reducing lag and stuttering.
What is Adaptive Sync?
Various gaming sequences necessitate a wide range of framerates. More effects and complexity (like as explosions and smoke), the longer it takes to render the variation in framerates. Instead of using the same framerate for all scenarios, it makes more sense to adjust the refresh rate based on the complexity of the scene.
On the fly, the display's refresh rate can be adjusted to match the GPU's output frames thanks to Adaptive Sync, which was developed by the VESA. To reduce input lag and screen tearing, every frame is displayed as quickly as feasible and never repeated.
Aside from video games, Adaptive Sync can also be utilized for smooth playback of multiple framerates, from 23.98 to 60 frames per second. Stutter-free video playback is achieved by adjusting the refresh rate of the monitor to match the framerate of the video source.
V-Sync VS Adaptive Sync: What’s the Difference?
Unlike V-Sync which caps your GPU’s frame rate to match with your display’s refresh rate, Adaptive Sync dynamically changes the monitor’s refresh rate in response to the game’s required framerates to render. This means it does not only annihilate screen tearing but also addresses the juddering effect that V-Sync causes when the FPS falls.
To illustrate Adaptive Sync with a diagram explained by VESA, you will see that Display A will wait till Render B is completed and ready before updating to Display B. This ensures that each frame is displayed as soon as possible, thus reducing the possibility of input lag. Frames will not be repeated within the display’s refresh rate set to avoid game stuttering. It will adapt the refresh rate to the rendering framerate to avoid any screen tearing.
AMD FreeSync VS NVIDIA G-Sync: What’s the Difference?
There is no difference between VESA Adaptive Sync and AMD FreeSync. It does this by employing VESA's royalty-free technology in order to synchronize the refresh rate with the frame per second. It is also compatible with the majority of monitors, which helps to keep costs low. However, AMD has chosen to leave the framerate range up to the discretion of the OEMs, which makes the sync technology less useful.
Both Adaptive Sync and NVIDIA G-Sync are based on the same fundamental idea. However, it is dependent on specialized circuitry that has to be incorporated within the display itself. Monitors that enable G-Sync come with additional hardware and are subject to stringent restrictions that are enforced by NVIDIA. As a result, the quality control on these monitors is more stringent, and therefore cost more.
Both of these solutions are limited by the hardware. If you already have a display that supports G-Sync, then you will need to purchase a graphics card made by NVIDIA. Similarly, an AMD graphics card is necessary in order to use a display that supports FreeSync. On the other hand, AMD has made the technology available for free usage as a component of the DisplayPort interface. Because of this, FreeSync is now accessible to users of competing devices. Monitors that are G-Sync Compatible can also be purchased to use in conjunction with an NVIDIA graphics processing unit (GPU).

Your requirements and personal preferences should guide your selection of a sync technology. It is recommended that your gaming monitor has Adaptive Sync capabilities in addition to V-Sync capabilities if you are looking for a more fluid gaming experience. If you play a lot of combat or shooting games, which demand accurate clicks and lightning-fast reflexes, then a few frames of difference can mean the difference between victory and defeat. This is especially true if you play a lot of games requiring lightning-fast reflexes.
