In other words the monitor is ready to move onto a new frame before the GPU is ready to send it. Some frames will be processed by the GPU more slowly than the monitor is able to display them. When the frame rate drops below the refresh rate of the monitor this disconnected feeling increases to a level that will bother a large number of users. It is still there, though, and some users feel it disconnects them from gameplay somewhat. On a 120Hz monitor the input lag penalty is half that of a 60Hz monitor and on a 144Hz monitor is even lower. Whilst this eliminates tearing, it also increases input lag as there is an inherent delay before frames are sent to the monitor. It also locks the frame rate to a maximum equal to the monitor’s refresh rate. The solution to this tearing is the ‘VSync on’ option which essentially forces the GPU to hold a frame until the monitor is ready to display it, as it has finished displaying the previous frame. Because only some of the screen is displaying the most recent information this can be thought of as a source of visual latency, too. Even if users don’t notice distinct tearing, the effect of that tearing (texture displacement and ‘juddering’) is often more obvious. It is generally less noticeable but it is definitely still there. Even on a 120Hz or 144Hz monitor, where some users incorrectly claim that there is no tearing, the tearing is still there. This results in a distinctive ‘tearing’ on the monitor that really bothers some users. This lack of synchronisation coupled with the nature of monitor refreshes (typically from top to bottom) causes the monitor to display a different frame towards the top of the screen vs. There is an excellent detailed technical explanation of these two modes and what they involve, using a 60Hz monitor in their example, on this AnandTech article.Īt the most basic level ‘VSync off’ allows the GPU to send frames to the monitor as soon as they have been processed, irrespective of whether the monitor has finished its refresh and is ready to move onto the next frame. They are forced to choose one of two main options that determine how the GPU handles its ‘passing of frames’ to the monitor– ‘VSync off’ or ‘VSync on’. This introduces something of a dilemma for gamers in particular. When running graphically intensive content, such as games, frame rate can be expected to fluctuate in response to varying levels of ‘demand’ from the game or application. Traditionally monitors operate at a fixed refresh rate – commonly 60Hz, 120Hz or 144Hz. How does G-SYNC act below the refresh rate floor of the monitor?.How does G-SYNC act at the refresh rate ceiling of the monitor?.Nvidia G-SYNC – a variable frame rate solution.Alternatively, it is possible to update your GPU drivers by using Nvidia's own software suite: GeForce Experience. To enable G-Sync functionality on a FreeSync monitor that lacks Nvidia's official certification, follow the walkthrough below.įirst, download and Install the latest GeForce Game Ready Drivers from Nvidia's official Driver Downloads page. Operating System: Windows 10/11 (64-bit).Driver Support: GeForce Game Ready Driver Version 417.71 (or newer).Supported Graphics Cards: Nvidia GeForce GTX 10/16-Series and RTX 20/30/40-Series GPUs.HDMI 2.0/2.1 support for G-Sync Compatible TVs and BFGD (Big Format Gaming Displays). Connection Options: DisplayPort 1.2 (or higher) for AMD FreeSync monitors.For G-Sync to work on a FreeSync display, ensure that your system meets the following requirements: Unlike AMD's FreeSync implementation, which works on both HDMI and DisplayPort (over USB Type-C as well), Nvidia's proprietary Adaptive-Sync solution seems somewhat limited in terms of connectivity. Nvidia G-Sync on AMD FreeSync Monitors: Setup and Compatibility Since both FreeSync and G-Sync technologies support VESA's (Video Electronics Standards Association) Adaptive-Sync protocol, any limitations that you might face are based solely on the manufacturing standards. For more information, check out Nvidia's official list of FreeSync monitors that have been certified as G-Sync Compatible.Īlthough official G-Sync Compatibility has its perks on quite a few occasions, it is possible to drive Nvidia's Adaptive-Sync solution on most non-certified FreeSync monitors, provided that you possess the right set of hardware. However, if the minimum VRR range went up to 75Hz, which does not comply with Nvidia's VRR threshold, the display loses an official "G-Sync Compatible" certification.Īs of November 2022, Nvidia has validated over 150 FreeSync monitors that can run G-Sync at an adequate VRR range. For instance, if your FreeSync monitor supports a wide VRR range of 48-144Hz, which is greater than Nvidia's recommended value of 2.4, G-Sync functionality should be enabled right out-of-the-box.
