Does Field of View Affect FPS Performance and Sensitivity? | QR #45

Welcome to another QR and in this one we’ll discuss the impact that Field of View can have on your FPS as well as another quite peculiar topic that’s related to mouse/controller sensitivity. Have you ever felt like your mouse sensitivity feels a little off right after you’ve changed your FoV settings? Well, that’s what happens but it also isn’t. The good news are that you’re not the only one so in this article, I’ll also try to explain how it works. Let’s begin!

Does Field of View Affect FPS Performance?

Yes, increasing the Field of View (FoV) will add more objects into the screen that will then be rendered by the GPU. In general, higher FOV in games means that you can detect enemies much easier but at the cost of performance.

Does Field of View Affect Sensitivity?

Wide field of view doesn’t impact sensitivity at all. All it does is adding more stuff in your screen which gives you the perception of lower sensitivity. In a narrow field of view on the other hand, things leave and enter your screen more often which can cause motion sickness.

Below you can see its impact when running Destiny 2 with a GTX 1060 at 1080p Ultra Settings.

Important Notes:

  1. The performance hit of Field of View is not the same for every game. For older games, the FPS reduction will be significantly lower since the extra objects that enter the screen are not as detailed as those of modern games.

Conclusion

To conclude, Field of View can dramatically decrease your FPS if you max it out. However, this is not a very viable way of playing any game. From my experience, as a person with motion sickness, I prefer increasing the FOV ever so slightly to make the game more enjoyable. At the end of the day, if you have a high-end graphics card, it’s up to your personal preferences to set it up. Let me know in the comments, if you have more questions.
