Understanding FPS and its importance

Before jumping into solutions, it’s crucial to comprehend what FPS is and why consistent frame rates matter in gaming. FPS stands for Frames Per Second, and it indicates the number of individual images (frames) that your computer displays each second. In simpler terms, it’s a measure of how smoothly a game runs.

High FPS generally translates to smoother animations and a more responsive gaming experience. On the other hand, when FPS drops, the game might stutter, lag, or freeze momentarily, greatly affecting gameplay. For fast-paced games like first-person shooters or racing games, a consistent and high FPS is crucial as it can make the difference between a game-winning move and a frustrating defeat.
