Let’s cut right to the chase because you’re here for a straight answer. Does motion blur increase FPS? The simple, direct answer is no. In fact, it almost always does the exact opposite: it decreases your FPS.
It feels counterintuitive, I know. I still remember getting my first real gaming PC over a decade ago. I’d spend hours in the settings menus of games like Crysis and The Elder Scrolls IV: Oblivion, tweaking every little slider and dropdown menu, convinced I could unlock some secret combination for perfect performance. I thought, “Hey, motion blur makes things blurry and less detailed, so surely my computer has to work less, right?” I toggled it on, expecting a magical FPS boost. The number didn’t go up. It went down.
That moment of confusion is precisely why this topic is so misunderstood. Motion blur is a graphical effect, an extra layer of paint the game has to apply to every single frame. It’s not a performance-saving shortcut; it’s a performance-costing feature. But why does it exist, and why do some people swear it makes their games feel smoother? Let’s dive deep into the world of simulated blur and what it’s really doing to your gaming experience.

What Exactly Is Motion Blur in Video Games Anyway?
Before we can properly talk about its effect on performance, we need to be on the same page about what motion blur actually is. In the simplest terms, motion blur is a visual effect that simulates the natural blurring our eyes perceive when we watch fast-moving objects. Think about waving your hand quickly in front of your face or watching a car speed down the highway. The edges soften, and you see a trail of motion.
Cameras produce a similar effect, especially in movies. Filmmakers use it deliberately to create a sense of speed and smooth, cinematic action. Video games adopted this technique to achieve that same “movie-like” quality and to make the on-screen action feel more dynamic and intense.
How Do Game Developers Actually Create This Blurring Effect?
It’s not just a simple smudge filter slapped over the screen. Developers typically use a couple of primary methods to create the effect, and how they do it directly relates to the performance cost.
- Per-Object Motion Blur: This is the more advanced and graphically intensive method. The game engine calculates the velocity of individual objects on the screen—your character, an enemy, a vehicle, a thrown grenade—and applies a custom blur to each one based on how fast it’s moving and in what direction. This looks incredibly realistic but requires a lot of computational power.
- Screen-Space Motion Blur (or Full-Screen Motion Blur): This is the more common and less demanding technique. Instead of tracking every object, the game’s engine analyzes the difference between the previous frame and the current frame. It then uses this data to create a blur effect across the entire screen, particularly when you whip the camera around quickly. It’s less precise but gets the job done with a much smaller hit to your FPS.
In both cases, your graphics card (GPU) is being given an additional job. It has to render the entire scene with all its textures, lighting, and shadows, and then it has to perform extra calculations to apply the blur effect on top of it all. More work always means more processing time, and that translates directly to fewer frames per second.
So, Why Do Some Gamers Believe Motion Blur Increases Performance?
This is the core of the confusion, and it’s based on a fascinating trick of human perception rather than technical reality. Motion blur doesn’t increase your frames per second, but it can absolutely make a low frame rate feel smoother.
Imagine you’re watching a flipbook animation. If you flip through it slowly, say at 20 pages per second, the animation will look choppy and stuttery. Each individual image is sharp and distinct. Now, imagine if each page in that flipbook had little “blur” lines drawn on it to indicate the direction of movement. As you flip through it at that same slow 20 pages per second, the choppiness would be less jarring. The blur helps your brain connect the motion between each distinct page, creating the illusion of smoother movement.
The Brain’s Interpretation: Perception vs. Reality
This is precisely what happens in video games. A game running at a shaky 30 FPS can look very stuttery. Each frame is on screen for a relatively long time, and the jump to the next frame is noticeable.
When you turn on motion blur:
- The effect helps to blend one frame into the next.
- The harsh, juddering transitions are softened.
- Your brain interprets this blended motion as being more fluid and continuous.
I ran into this exact scenario years ago trying to play a notoriously demanding game on a PC that was, let’s be honest, not quite up to the task. The framerate was hovering around an unstable 25-35 FPS. It was a mess of stutters. In a moment of desperation, I turned on motion blur. My FPS counter didn’t budge—in fact, it dipped by a couple of frames—but the game suddenly felt more playable. My brain was being tricked, and in that case, I was happy to be fooled. This is also a major reason why developers enable it by default in many console games that are locked to 30 FPS. It’s a deliberate artistic and technical choice to mask the lower framerate and make it feel more cinematic.
Let’s Get Technical: How Much Does Motion Blur Actually Impact Your FPS?
The performance hit from motion blur isn’t a fixed number; it varies wildly depending on several factors: the game itself, the quality of the motion blur implementation, your graphics settings, and of course, your PC’s hardware.
To get some concrete, real-world data for this article, I decided to do a little “at-home” research. I fired up my rig, which is a fairly standard mid-to-high-end build, and ran a few tests in a couple of popular games. I used monitoring software to track the average FPS in a repeatable section of each game, first with motion blur completely off, and then with it cranked to its highest setting.
My Personal Performance Test Results
Here’s a breakdown of what I found, which should give you a general idea of the performance cost you can expect.
- In a Graphically Intense RPG (Cyberpunk 2077): This game is a visual powerhouse. In a busy city scene with lots of movement, turning motion blur from off to high resulted in a performance drop of about 6-10 FPS. That’s a significant chunk, especially if you’re trying to maintain a stable 60 FPS.
- In a Fast-Paced, Well-Optimized Shooter (DOOM Eternal): This game is famous for its incredible optimization. The impact here was much smaller. Toggling on motion blur only cost me about 3-5 FPS. While not huge, in a game this fast, many competitive players would still trade that for maximum performance.
- In a Popular Indie Game (Hades): In a less graphically demanding title like this, the impact was almost zero. The simple art style and top-down perspective meant the motion blur effect was very lightweight, and I barely registered a 1-2 FPS difference.
What does this tell us? The more complex the scene and the more advanced the motion blur effect, the bigger the performance penalty.
When Should You Consider Using Motion Blur?
Despite the performance cost, motion blur isn’t a universally “bad” setting. There are legitimate reasons why you might choose to turn it on. It really boils down to personal preference and what you’re trying to achieve with your gaming experience.
You’re Chasing That Cinematic, Movie-Like Feel
For many gamers, immersion is everything. If you’re playing a story-heavy, single-player game like The Last of Us or Red Dead Redemption 2, your goal isn’t necessarily to have the highest possible framerate. You want the experience to feel like a blockbuster movie. Motion blur can significantly contribute to that cinematic quality, making sweeping camera movements and frantic action sequences feel more epic and polished. In these cases, sacrificing a few frames per second for a huge boost in atmospheric presentation can be a worthwhile trade-off.
You’re Gaming on a Console or at a Lower Framerate
As mentioned earlier, motion blur is a console developer’s best friend. When you’re locked at 30 FPS, making the game feel smooth is a top priority. Motion blur works wonders here, helping to hide the inherent choppiness of that lower framerate. If you’re playing on a PC that struggles to maintain a high FPS and you find the stuttering distracting, enabling motion blur might paradoxically make the game feel better to play, even with the slight performance dip.
When Should You Absolutely Turn Motion Blur Off?
On the flip side, there are definite situations where enabling motion blur is a clear disadvantage. For a large portion of the PC gaming community, especially those with a competitive streak, it’s one of the very first settings they disable in any new game.
Here are the times you should head straight to the graphics menu and turn it off:
- You Play Competitive Multiplayer Games: In titles like Counter-Strike, Valorant, Call of Duty, or Apex Legends, clarity is king. You need to be able to spot an enemy in a fraction of a second. Motion blur actively works against this by smearing details and obscuring your vision, especially while you’re turning quickly. Every top-tier competitive player turns it off for a reason: it’s a competitive handicap.
- You’re Chasing the Highest Possible FPS: If your goal is raw performance—maybe you’re trying to take full advantage of a 144Hz or 240Hz monitor—then every single frame counts. Disabling motion blur is one of the easiest ways to claw back a few extra frames without a major degradation in core visual quality like textures or shadows.
- You Suffer from Motion Sickness: For a not-insignificant number of people, the artificial blur effect can be disorienting and even induce nausea or headaches. Our brains are used to a certain kind of natural motion blur, and when a game’s implementation doesn’t feel right, it can be extremely uncomfortable. If you ever feel queasy while playing, motion blur is a prime suspect and should be the first setting you experiment with disabling.
The Psychology of Blur: Why Our Brains Accept the Illusion
It’s fascinating how readily our brains fill in the gaps to create a sense of fluid motion. This isn’t just a gaming phenomenon; it’s fundamental to how we perceive the world. Visual information is processed in a way that prioritizes a continuous, stable reality over a series of disjointed snapshots.
This concept is related to deeper topics in visual psychology. For instance, research from institutions like Purdue University on the topic of “change blindness” has explored how people can miss major changes in their visual field if their attention is disrupted. While not exactly the same, it highlights a key principle: our brains are constantly making assumptions and smoothing over imperfections to present a coherent narrative of what we’re seeing. Game developers cleverly leverage this trait. By strategically adding blur, they feed our brain the cues it needs to perceive smooth motion, even when the underlying technical data (the framerate) is less than perfect.
The Final Verdict: To Blur or Not to Blur?
An emphatic no. It is a post-processing effect that costs performance, plain and simple.
However, the more important question is, “Should you use it?” And that answer is entirely up to you. It’s a classic battle between objective performance and subjective feel.
Think of it like this: motion blur is a tool. For a competitive gamer, it’s the wrong tool for the job—like using a paintbrush to hammer a nail. For a cinematic single-player enthusiast, it can be the perfect tool to add that final layer of immersive polish.
My personal approach has evolved over the years. When I’m playing a fast-paced online shooter, motion blur is off before I even load into the first match. But when I’m settling in for a long session with a beautiful open-world RPG on a weekend, I sometimes toggle it on. I’ll take the small FPS hit for the enhanced cinematic vibe.
The best thing you can do is experiment. The next time you launch a game, don’t just stick with the default settings. Play a section with motion blur off. Then, turn it on and play the same part again. Pay attention not just to your FPS counter, but to how the game feels to you. In the end, that’s all that really matters.
