No matter how fancy new consoles get, PCs are still on the cutting edge of gaming tech. They allow for greater graphical fidelity and motion smoothing than PlayStation 5 and Xbox Series X can fathom. However, these advantages have their own downsides as well: your frame rate is likely to jump around more than on a typical console.
In a particularly demanding scene, you might get 45 frames per second, while easier-to-render scenes can jump all the way into the hundreds. That much variance can introduce annoyances like stuttering and screen tearing, or if you turn on Vertical Sync added input lag.
