Does Capping FPS Improve Performance?

Imagine yourself in the heat of a virtual battle, adrenaline pumping as you dodge bullets and unleash attacks. Suddenly, the game stutters, your character freezes mid-action, and your immersion shatters. What happened? This is where Frames Per Second (FPS) comes in.

FPS is a crucial metric in gaming, representing the number of images your graphics card (GPU) can render and your monitor can display in one second. Higher FPS translates to smoother, more responsive gameplay, while lower FPS can result in choppy visuals and lag.

But what if there was a way to potentially improve performance even further? Enter capping FPS, which involves setting a maximum limit on the number of frames your GPU renders. While it might seem counterintuitive, capping FPS can offer several benefits, but also comes with some potential drawbacks. Let’s delve deeper and explore both sides of the coin.

Does Capping FPS Improve Performance?

Capping FPS, or frames per second, can actually improve performance in several ways, even though it might seem counterintuitive.

Arguments for Capping FPS

Reduced System Workload

Think of your computer as a team working on a project. The GPU is the lead artist, responsible for crafting the visuals. When uncapped, the GPU pushes out as many frames as possible, demanding significant resources. Capping FPS acts like a project deadline, telling the GPU to prioritize quality within a specific timeframe. This frees up resources for other components like the CPU, potentially leading to:

  • Smoother gameplay: By alleviating the GPU’s workload, the CPU can dedicate more processing power to other game aspects like physics and AI, leading to a more responsive experience.
  • Reduced stuttering: Stuttering occurs when frames are delivered unevenly, causing the game to appear to “hitch.” Capping FPS helps maintain a consistent frame rate, minimizing stutter and ensuring a smoother flow.

Lower Power Consumption

Capping FPS effectively reduces the workload on your GPU

Just like a car engine working harder consumes more fuel, your computer components use more electricity when under heavy load. Capping FPS effectively reduces the workload on your GPU, leading to:

  • Lower electricity bills: This benefit is particularly noticeable for desktop PCs, where prolonged gaming sessions can contribute noticeably to your electricity usage.
  • Extended battery life: For laptops, capping FPS can significantly improve battery life, allowing you to game for longer without needing to plug in.

Cooler Operation

Less workload translates to less heat generation. This is beneficial for several reasons:

  • Quieter fan noise: Your computer’s fans spin faster to dissipate heat. By reducing heat generation, capping FPS can lead to quieter operation, making your gaming sessions more peaceful.
  • Potentially longer lifespan for hardware components: Excessive heat can shorten the lifespan of your hardware. Capping FPS can help keep your components cooler, potentially extending their longevity.

Mitigating Screen Tearing (Optional)

Capping the FPS to match the refresh rate can help prevent this visual artifact

On monitors without G-Sync or FreeSync technology, exceeding the monitor’s refresh rate can lead to screen tearing, where the image appears to be ripped apart horizontally. Capping the FPS to match the refresh rate can help prevent this visual artifact.

Arguments Against Capping FPS

Reduced Visual Fluidity (for very high refresh rate monitors)

While capping FPS generally improves smoothness for most gamers, those using high refresh rate monitors (e.g., 240Hz) might perceive a slight reduction in visual fluidity when capping the FPS below the refresh rate. This is because the monitor can still display more frames than the GPU is rendering, potentially leading to a less responsive feeling.

Potential for Input Lag (especially with certain methods)

Input lag refers to the delay between your input (e.g., pressing a button) and the corresponding action happening on screen. While capping FPS can improve overall performance, some methods, like Vsync, can introduce slightly higher input lag. This might be noticeable in fast-paced games where even small delays can affect your performance. However, alternative methods like in-game frame limiters often have minimal impact on input lag.

Final Thoughts

Capping FPS is a double-edged sword. While it can offer numerous benefits like reduced system workload, lower power consumption, cooler operation, and potentially smoother gameplay, it might also come with drawbacks like reduced visual fluidity for high refresh rate monitors and potential for slightly higher input lag with specific methods.

Ultimately, the decision to cap FPS depends on your individual preferences, hardware capabilities, and specific game requirements. Experiment with different settings and find the sweet spot that balances performance and visual fidelity for the most enjoyable gaming experience.


Q. What is the best FPS cap for my system?
A. There’s no one-size-fits-all answer, as the ideal FPS cap depends on your monitor’s refresh rate, hardware specifications, and personal preference. Experiment with different caps and find the one that offers the best balance.

Q. How do I cap FPS in games?
A. Most modern games offer built-in frame limiter options within the graphics settings menu. Alternatively, you can use your graphics card’s control panel (e.g., NVIDIA Control Panel or AMD Radeon Settings) to set a global FPS cap that applies to all games.

Q. Should I use Vsync instead of capping FPS?
A. Vsync synchronizes the frame rate with your monitor’s refresh rate, potentially eliminating screen tearing but also introducing some input lag. If screen tearing is a significant issue and you don’t mind slightly higher input lag, Vsync can be a good option. However, for the best balance of performance and responsiveness, capping FPS directly might be preferable.

Q. Will capping FPS affect my online gaming performance?
A. Capping FPS shouldn’t directly impact your online gaming performance in terms of latency or ping (connection speed to the server). However, if capping FPS introduces significant input lag, it might affect your reaction time and overall performance in fast-paced games.

Q. Are there any downsides to not capping FPS?
A. While not capping FPS can potentially offer the highest possible frame rates, it can also lead to:

  • Increased system workload: This can put a strain on your hardware, potentially leading to stuttering, especially on older or less powerful systems.
  • Higher power consumption: This can result in increased electricity bills and shorter battery life for laptops.
  • Louder fan noise: Due to the increased workload and heat generation, your computer’s fans might need to spin faster, making more noise.
