This software comes along with your graphics drivers and there’s no need to install it separately. If you have a supported GeForce GTX graphics card that is GTX 960 or newer, you will be able to easily enable it on the NVIDIA Control Panel. In conclusion, if you aim to completely eliminate all screen tearing issues, you need to enable Fast-Sync as well, in a G-Sync capable monitor.Įnable Fast Sync Using NVIDIA Control Panel That being said, G-Sync doesn’t eliminate screen tearing if the rendering rate of the GPU is above your monitor’s refresh rate. In order to solve this, you’ll need a G-Sync monitor that eliminates screen tearing by reducing the monitor’s refresh rate to the GPU’s rendering rate. This means you’ll still experience screen tearing if the GPU is rendering at a frame rate lower than the monitor’s refresh rate. It’s worth noting that Fast Sync only works as along as the GPU is rendering at a frame rate above the monitors refresh rate. As a result of this, the game engine is not slowed down as the Back buffer is always available for the GPU to render to, and you don’t experience screen tearing as there’s always a frame store in the front buffer for the scan, thanks to the inclusion of Last Rendered buffer. Now, the Last Rendered Buffer sends the frame to the front buffer for scanning and displaying it on the monitor. In the meantime, the Front buffer undergoes the scanning process, and the image is then sent to the monitor. Initially, the GPU renders a frame into the Back buffer, and then the frame in the Back buffer is immediately moved to the Last Rendered Buffer. After this, the GPU renders the next frame into the back buffer and while this happens, the frame in the last rendered buffer is moved to the front buffer. Now the Last Rendered buffer waits for the next frame, from the back buffer. NVIDIA manages to make this possible by introducing a new additional “ Last Rendered Buffer” that sits right between the Front and Back buffer. With Fast Sync, that’s not the case at all, as the latency is significantly minimized and pretty close to what you’d get when V-Sync is turned off. Nowadays, most of the gamers prefer keeping V-Sync disabled as the latency could even go over 100 ms. One of the biggest disadvantages of enabling V-Sync for gaming is input lag, which hinders the gaming experience, especially if you’re playing fast-paced games. NVIDIA Fast Sync is the company’s newest solution to fix all the screen tearing issues, while keeping latency to a bare minimum, thereby making it a much better option than the traditional V-Sync technology.
