Does Anti Aliasing Lower Fps?

Anti-aliasing has become a popular technique to improve the visual quality of graphics in video games. It smooths the jagged edges of lines and edges by blending the colors of pixels. However, there is a widely held belief that anti-aliasing negatively impacts the performance of video games, specifically by lowering the frames per second (FPS).

FPS is an essential metric in gaming, and players want to achieve the highest possible FPS for a smooth experience. It is evident that anti-aliasing requires system resources to execute, and it’s a reasonable assumption that it can compromise FPS. In this article, we will delve deeper into the concept of anti-aliasing and how it affects the gaming performance, specifically FPS.

Does Anti-Aliasing Lower FPS?

Anti-aliasing is a technique used in computer graphics to smooth out jagged edges and create a more visually appealing image. However, it requires additional processing power and can impact overall performance, including FPS (frames per second).

Here are some key points to consider regarding anti-aliasing and FPS:

– Anti-aliasing can lower FPS. This is because the graphics card has to work harder to process the additional calculations needed to smooth out edges and create the anti-aliasing effect.
– The impact on FPS can vary depending on the level of anti-aliasing used. Higher levels require more processing power and can have a bigger impact on FPS.
– Some games and graphics cards may have built-in optimization settings to balance anti-aliasing and FPS. For example, a game may offer different anti-aliasing options (such as FXAA or MSAA) that have varying levels of impact on performance.
– Lowering anti-aliasing settings can improve FPS, but it may also result in a less visually appealing image with jagged edges. Finding the right balance between visual quality and performance is key.
– Overall system specs, the specific game being played, and other factors can also impact FPS in addition to anti-aliasing. It’s important to consider all of these factors when trying to optimize performance.


1. Does anti-aliasing affect FPS?

Yes, anti-aliasing can lower FPS as it requires additional processing power from your graphics card to smooth out jagged edges in images and reduce aliasing.

2. How can I reduce the impact of anti-aliasing on FPS?

You can reduce the impact by lowering your anti-aliasing settings, using a less demanding form of anti-aliasing, or upgrading your graphics card to handle higher levels of anti-aliasing.

3. Do all games support anti-aliasing?

No, not all games support anti-aliasing. Some older games or games with simpler graphics may not have anti-aliasing options available or may have limited options.

4. Are there any benefits to using anti-aliasing?

Yes, anti-aliasing helps to improve image quality by smoothing out jagged edges and reducing aliasing, which can make images look sharper and more realistic.

5. Is it worth sacrificing FPS for better anti-aliasing quality?

It depends on your personal preferences and the type of games you play. For some, smooth, realistic graphics may be more important than FPS, while others may prioritize performance over image quality.


In summary, anti-aliasing is a helpful tool that enhances the visual quality of your games. However, it can negatively impact your FPS, especially on lower-end hardware. It’s essential to consider your system’s capabilities before enabling this feature. You can also adjust the settings to find the right balance between image quality and performance. By doing so, you can enjoy smooth and stunning visuals without compromising your gameplay experience.
