Have you ever been exploring a stunning new savanna biome in Minecraft, panning your view across the horizon, only to see a weird, jagged line rip across the middle of your screen? It’s not a bug in the game or a new, terrifying mob. That distracting visual glitch is called screen tearing, and frankly, it can completely ruin the immersion. The good news is, there’s a simple setting built right into Minecraft to fix it, but it comes with its own set of confusing trade-offs. So, what is VSync in Minecraft, and should you actually use it?
Let’s dive deep into this. I remember years ago, running Minecraft on my first real gaming PC build. I was so proud of hitting over 200 frames per second (FPS). But then I noticed it—that ugly tear every time I moved quickly. I thought my brand-new graphics card was broken. It turns out, my hardware was working too well for my monitor, and VSync was the answer I was looking for. It’s not just a button; it’s a piece of tech with a fascinating job to do.

What Exactly Is That Horrible Screen Tearing I’m Seeing?
Before we can even talk about the fix, we have to understand the problem. Screen tearing is a visual artifact that happens when your graphics card (GPU) is sending out new frames faster than your monitor can display them.
Think of it this way: your monitor refreshes the picture on its screen a specific number of times per second. This is called its “refresh rate,” measured in Hertz (Hz). A standard monitor is 60Hz, meaning it draws a new image 60 times every second. Meanwhile, your GPU is working hard to produce as many frames as it can, measured in FPS.
When your GPU is cranking out, say, 100 FPS while your monitor is still trying to draw a single 60Hz image, they get out of sync. The monitor might start drawing a new frame from the top of the screen, but before it can finish, the GPU sends another new frame. The monitor, trying to keep up, then starts drawing the second frame from the middle of the screen downwards. The result? The top half of your screen shows one frame, and the bottom half shows another, with a nasty tear in between.
It’s most noticeable during fast motion, like:
- Quickly looking around in a PvP fight.
- Flying with an Elytra.
- Galloping on a horse across the plains.
Essentially, your GPU and monitor are having a communication breakdown, and your eyes are the ones that suffer.
So, How Does VSync Come to the Rescue?
This brings us to the core question. VSync, which stands for Vertical Synchronization, is a graphics technology that acts like a traffic cop between your GPU and your monitor. Its one and only job is to force your graphics card to slow down and wait for the monitor to be ready for a new frame.
When you turn VSync on in Minecraft, you are telling the game: “Hey, don’t send a new frame until the monitor has completely finished drawing the last one.” This simple command synchronizes the two components. Your GPU’s frame rate is effectively capped at your monitor’s refresh rate.
- If you have a 60Hz monitor, VSync will lock your Minecraft FPS to 60.
- If you have a 144Hz gaming monitor, VSync will lock your FPS to 144.
By making the GPU wait its turn, VSync completely eliminates screen tearing. That jagged line vanishes, and you get a perfectly whole, smooth image every single time the screen refreshes. Problem solved, right? Well, mostly.
Should I Turn VSync On? The Pros and Cons
This is where things get a bit more personal, and there’s no single right answer. Turning on VSync is a trade-off. For some players, it’s an absolute necessity. For others, it’s a feature they wouldn’t touch with a ten-foot pole.
Why You Might Want to Enable VSync
The most obvious reason is, of course, to get rid of screen tearing. If those visual glitches are driving you crazy, VSync is the most direct solution. It provides a tear-free, stable, and visually consistent experience.
Additionally, because VSync stops your GPU from running at 100% all the time, it can actually lead to some nice side benefits. Your GPU won’t have to work as hard, which means it may run cooler and consume less power. I noticed this on my laptop when playing on the go; turning on VSync gave me a little extra battery life and kept the fans from sounding like a jet engine.
So, What’s the Catch with VSync?
The single biggest drawback, and the reason many competitive players avoid VSync, is input lag.
Input lag is the delay between you performing an action (like clicking your mouse or pressing a key) and seeing the result on screen. Because VSync forces your GPU to wait before sending a frame, it introduces a small delay into the entire process. The frame sits in a buffer, waiting for the monitor’s signal.
Does this matter? It depends entirely on what you’re doing.
If you’re calmly building a new base in your single-player survival world or just exploring, a few extra milliseconds of delay is completely unnoticeable. You won’t feel it at all.
However, if you’re in a fast-paced PvP battle in Bed Wars or trying to land a critical hit on the Ender Dragon, that tiny delay can be the difference between winning and losing. You click to place a block to save yourself from falling into the void, but because of the input lag, the action registers a moment too late. For this reason, many serious gamers prefer to deal with a bit of screen tearing in exchange for the most responsive controls possible.
Another issue can pop up if your PC struggles to consistently produce frames at your monitor’s refresh rate. If you have a 60Hz monitor and your FPS suddenly drops to 55, VSync might overcorrect and drop your FPS all the way down to 30 to maintain stability. This can cause noticeable stuttering, which can feel even worse than tearing.
How Do I Actually Enable VSync in Minecraft?
Alright, let’s say you’ve decided to give it a try. Finding the setting is incredibly easy. Here’s a quick step-by-step guide to turning on VSync.
- Launch Minecraft and from the main menu, click on Options….
- Next, navigate to the Video Settings….
- Inside the Video Settings, look for the Use VSync option. It’s usually on the right-hand side, about halfway down the list.
- Simply click the button to toggle it On or Off.
- Click Done to save your changes and head back to your game.
That’s it! You can toggle this setting anytime, even while in a world, to see the difference for yourself in real-time. I’d recommend finding a spot with a lot of detail and quickly panning your camera back and forth with VSync off, then turning it on and doing the same thing. The difference should be immediately obvious.
Are There Any Alternatives to VSync?
What if you hate screen tearing but also can’t stand the input lag from VSync? For years, this was just a compromise we had to live with. Thankfully, technology has moved on, and we now have better options, assuming your hardware supports them.
The modern solution is called Adaptive Sync. You’ve probably heard of the two major brand names for this technology:
- NVIDIA G-Sync
- AMD FreeSync
Unlike VSync which forces the GPU to match the monitor, Adaptive Sync does the opposite: it allows the monitor’s refresh rate to dynamically match the frame rate of your GPU. If your game is running at 87 FPS, your monitor will refresh at 87Hz. If it drops to 72 FPS, the monitor instantly adjusts to 72Hz.
This is the best of both worlds. It eliminates screen tearing completely because the two are always in sync, and it does so without adding the significant input lag of VSync. The experience is incredibly smooth and responsive.
The only downside is that you need a compatible monitor (one that has G-Sync or FreeSync technology) and a compatible graphics card to use it. It’s a hardware solution, not just a software setting. I spent a long time debating whether the upgrade was worth it, and after finally getting a FreeSync monitor a couple of years back, I can honestly say I’ll never go back.
For a deeper technical dive into how these display technologies work, the computer science department at Stanford University has some great educational materials on graphics processing that touch on the core principles of synchronization. You can often find course notes online like this example on graphics hardware that explain the foundations.
Let’s Talk About Refresh Rate (Hz) vs. Frame Rate (FPS)
To truly make an informed decision, it helps to properly understand these two terms. People often use them interchangeably, but they describe two very different things.
- Frame Rate (FPS): This is all about your PC’s performance. It’s a measure of how many frames your graphics card is capable of rendering each second. Higher FPS generally means smoother-looking gameplay. This is a measure of your GPU’s output.
- Refresh Rate (Hz): This is a specification of your monitor. It’s a measure of how many times your monitor can redraw the entire screen each second. A higher refresh rate allows for a clearer picture with less motion blur. This is a measure of your monitor’s capability.
The goal for perfect gameplay is to have these two values align as closely as possible. VSync is a brute-force method of achieving this alignment. It caps your powerful GPU’s FPS to match your monitor’s fixed Hz. Adaptive Sync, on the other hand, is an elegant solution that makes your monitor’s Hz flexible to match your GPU’s fluctuating FPS.
So, What’s the Final Verdict on VSync in Minecraft?
After all this discussion, here is my personal take, based on years of playing on all sorts of different computers. There is no magic setting that is right for everyone. It all comes down to you, your hardware, and how you play.
I would recommend you turn VSync ON if:
- You are playing in a relaxed, single-player, or creative mode.
- Screen tearing is very noticeable and bothers you a lot.
- You want to potentially reduce your GPU’s temperature and power consumption.
- You don’t play competitive game modes where split-second reactions are critical.
Conversely, I would recommend you turn VSync OFF if:
- You primarily play fast-paced, competitive PvP servers (SkyWars, Bed Wars, etc.).
- You are extremely sensitive to input lag and want your game to feel as responsive as possible.
- Your computer struggles to maintain an FPS equal to your monitor’s refresh rate, as VSync could cause stuttering.
- You have a G-Sync or FreeSync monitor and have it enabled, as VSync becomes redundant and can sometimes interfere with it.
The best thing you can do is experiment. Load up your favorite world or server. Play for ten minutes with it on. Then, play for ten minutes with it off. Go with what feels best to you. At the end of the day, Minecraft is about having fun, and the right settings are whichever ones make your experience the most enjoyable.

What are the downsides of using VSync in Minecraft?
The main downsides of VSync include potential input lag, which can cause a slight delay between your actions and on-screen responses, and possible stuttering if your hardware struggles to maintain a stable high FPS. It can also limit your maximum FPS to your monitor’s refresh rate.
Should I enable VSync in Minecraft?
Enabling VSync is recommended if you experience distracting screen tearing and do not prioritize the fastest response time. It provides a smoother visual experience, especially for casual gameplay and building. However, serious PvP players may prefer to keep it off for lower input lag.
Why does screen tearing happen in Minecraft?
Screen tearing occurs when the GPU’s frame rate exceeds the monitor’s refresh rate, causing the monitor to display parts of two different frames simultaneously. This usually happens when the game runs at a higher FPS than the monitor’s refresh rate, leading to a torn appearance on the screen.
What is VSync in Minecraft and how does it work?
VSync in Minecraft is a setting that synchronizes the game’s frame rate with your monitor’s refresh rate to prevent screen tearing. When enabled, it makes the GPU wait for the monitor to be ready before sending a new frame, ensuring only full frames are displayed for smoother gameplay.
