![]() Not only that but V-Sync can create awful input lag. Obviously, this is a problem since you are not getting the full frame rate that your graphics card is capable of producing. If your monitor is a 60hz monitor but you have a fancy GTX1080 which is providing you with a frame rate of 200 then your frame rate will be locked to 60. V-Sync locks your frame rate to the refresh rate of your monitor. G-Sync was designed to improve upon what V-Sync was trying to do. This stops the chance of any tearing whatsoever. Some say it is also beneficial to set your frame rate limit to be a couple of fps below your monitors refresh rate. Be careful if you are setting your frame rate to unlimited as this could cause tearing or stuttering. In most games, there is a setting or frame rate limit. For example, if your monitors refresh rate is 144hz then the technology can only prevent tearing for when your frame rate is below 144 fps. It is important to note that G-Sync is only effective for when your frame rate is lower than your monitors refresh rate. You can find a full list of supported cards here. However, nowadays the majority of NVIDIA cards are G-Sync ready unless you have an older card. In order for G-Sync to work your graphics card also has to be G-Sync ready. Which provides the player with crisp, smooth frames. G-Sync allows monitors to support a wide array of refresh rates that might be redrawn at significantly different times. This is what stops the screen tearing and jagged edges because the monitor is only receiving the information when it is ready. ![]() With G-Sync the graphics card will wait until the monitor is ready to receive the next frame before sending it. VBLANK just means the time between when a monitor is finished rendering the current frame and the start of the next frame.ĭuring this tiny frame of time, no refresh data is being transmitted to the monitor. ![]() The G-Sync module manipulates the display panels vertical blanking interval (VBLANK). V-Sync also tries to perform the same task however it does so with the added negative effect of input lag which I will discuss in more detail later. It is almost like your monitor is playing catch-up. This is because your monitor is not capable of rendering the frames in time in relation to how fast your graphics card is producing the information. If your graphics card is powerful enough to be providing you with a high frame rate but you are seeing screen tearing or weird jagged edges then this is what G-Sync aims to solve.
