NVIDIA G-Sync is a technology designed to eliminate screen tearing and reduce stuttering in video games. It synchronizes the refresh rate of a monitor with the frame rate of a graphics card, ensuring smoother gameplay and a more immersive experience. This is particularly beneficial in fast-paced games where visual clarity is crucial. G-Sync requires a compatible monitor and NVIDIA graphics card to function. When the frame rate fluctuates, G-Sync dynamically adjusts the monitor's refresh rate, allowing for seamless transitions. This results in a more fluid visual experience, enhancing both performance and enjoyment for gamers.
