What Is Screen Tearing and How to Fix It in Games

5 min read

Screen tearing is the horizontal split that appears when a game shows parts of two different frames at once. A line cuts across the picture, and the top and bottom halves seem slightly out of step, especially during fast camera turns. It is not a broken screen, and it is one of the most common visual faults in PC gaming.

This guide explains what screen tearing is and how to fix it in games. You will learn why the graphics card and the monitor fall out of sync, which settings stop the tearing, and which fix suits your hardware.

What Screen Tearing Actually Is

A monitor redraws the picture at a fixed rate, called the refresh rate. A graphics card draws frames as fast as it can, at a variable rate. When the graphics card delivers a new frame in the middle of a monitor refresh, the monitor shows the top of the new frame and the bottom of the old one. The seam between them is the tear you see.

Tearing is most visible during fast horizontal movement, because the two frame halves differ the most then. A quick camera pan in a shooter, a fast drive past roadside objects, or a rapid turn in a racing game all make the seam obvious. In slow scenes, the two halves look nearly identical, and the tear hides.

Tearing is a timing problem, not a quality problem. The graphics card and the monitor are both working correctly; they are simply not working to the same clock. Every fix for tearing works by syncing the two clocks, by holding frames until the monitor is ready, or by letting the monitor adapt to the graphics card.

VSync: The Classic Fix and Its Cost

Vertical sync, or VSync, forces the graphics card to wait for the monitor before delivering each frame. The graphics card holds the finished frame until the monitor starts a new refresh, so every refresh shows exactly one complete frame, and tearing vanishes. It is the oldest fix, and it is built into nearly every game.

VSync has a cost: input lag. Because frames wait for the refresh, your mouse movement and key presses reach the screen slightly later. In slow games the delay is barely noticeable, but in competitive shooters it can make aiming feel sluggish.

Use VSync when tearing bothers you more than a small delay, and when your frame rate stays above the refresh rate. In story-driven games and relaxed play, VSync is a good trade. In fast competitive games, the adaptive sync options below are usually the better answer.

Adaptive Sync: G-Sync, FreeSync, and VRR

Adaptive sync flips the problem around: instead of forcing the graphics card to match the monitor, it lets the monitor match the graphics card. A monitor with G-Sync, FreeSync, or generic variable refresh rate support changes its refresh timing to match each frame as it arrives.

Check that adaptive sync is enabled in two places. Turn it on in the monitor on-screen menu, and turn it on in the graphics driver settings on the computer. Both switches must be on, and the game must run in fullscreen or borderless mode as the driver requires.

Match the monitor to your graphics card brand if you are buying new. FreeSync monitors work with most modern graphics cards, while G-Sync support depends on the monitor and driver combination.

Frame Rate Caps and Triple Buffering

Capping the frame rate just below the refresh rate is a cheap fix that helps even without adaptive sync. If your monitor runs at 60 hertz, cap the game at 58 or 59 frames per second.

Triple buffering is a middle option. It gives the graphics card an extra frame buffer, so the card can keep working while one frame waits for the monitor. Triple buffering reduces the stutter that VSync causes when the frame rate dips, at the cost of a little more input lag and memory.

Many games offer these options in their graphics menus, and the graphics driver can force them globally. Try the in-game cap first, since it is the simplest, and add triple buffering only if the game still stutters with VSync on. Change one setting at a time, so you can tell which change actually helped.

Choosing the Right Fix for Your Setup

If your monitor supports adaptive sync, use it. Enable it in the monitor menu and the driver, turn VSync off in the game or set it to the adaptive mode, and cap the frame rate a few frames below the refresh rate. This combination gives a tear-free picture with the lowest input lag, and it is the setup most gamers should aim for.

If your monitor has no adaptive sync, use VSync for slow games and a frame rate cap for fast games. Accept a little input lag in story games, where tearing is more distracting than delay. In competitive games, prefer the cap and live with rare tears, since a fast response matters more than a perfect picture.

If tearing persists after every setting change, check the cable and the port. A damaged cable or a port that cannot carry the refresh rate can produce artifacts that look like tearing but are really signal errors.
