When buying a gaming monitor with higher refresh rates, most of the monitors comes with one of these FreeSync or G-Sync certifications but what are these certifications and which one is best for you and which performs well in gaming? Before that let’s have a quick overview of VSync and Screen-Tearing.
Normally when buying a gaming monitor, we have many different variants with different refresh rates. A higher refresh rate means how many times the monitor refreshes within one second. In gaming, the FPS rate(Frames Per Second) is used to show how many frames are getting rendered withing one second. In the marketplace, manufacturers have to specify this refresh rate for each monitor or else according to the standards it’s a monitor with 60Hz refresh rate when it’s not specified.
With the huge improvement of the technology, GPUs are getting much better in performances so when using a well-performing graphics card or the game you are playing is quite old, the GPU can push more frames to your monitor more than it’s designed. For example, if your monitor has 60HZ refresh rate and you are playing GTA V with an RTX 3080, it’s definitely sure the GPU can push the FPS rate to 80-90 range. Due to this, the monitor is getting pushed too hard and as a result Screen Tearing occurs and this gives a bad experience to the gamers in competitive gaming as well as in normal gaming
As a solution, the VSync or Vertical Sync came to life, and the mechanism is to limit the GPU performances to the maximum limit of your monitor without pushing beyond the limits. Although the explanation is simple, this process is quite complicated because a game should be able to function according to players inputs and commands. But when limiting the performances can cause to input lags which makes a delay in displaying the responses according to the inputs given by the users and also FPS Drops and Shutterings can also occur due to holding the GPU.
Because of these drawbacks, VSync technology had failed to solve these issues in gaming. After that the VESA organization bough up some standards and introduced Adaptive SYNC technology to the display ports on the standard of DP 1.2a
Based on this adaptive sync technology, AMD introduced the FreeSync technology and Nvidia introduced there G-Sync technology to the gaming industry. Doesn’t matter whether it’s FreeSync or G-Sync, both of these technologies can improve the gaming experience without limiting the GPU performances.
What are FreeSync and G-Sync
Both FreeSync and G-Sync are known as adaptive sync technologies and they serve as an alternative to V-Sync which you can find in the graphics menu in many video games. In the adaptive sync mode, both monitor and GPU are getting synchonize in the same method. By that, the monitor can perform with a variable frame rate which can be given by the graphics card. The monitor can adjust the refresh rate according to the performances of the GPU without limiting the performances. To maintain this process a scaler unit was developed and by combining with the GPU, the refresh rate of the monitor is getting controlled according to the GPU performance.
FreeSync is an open standard produced by AMD so that any manufacturer can buy the AMD scaler unit and manufacture the monitors while Nvidia kept that as a proprietary service which manufacturers have to buy the license directly from Nvidia and manufacture the monitors according to the strict guidelines over the developments, panels, certifications and etc. For this reason, Freesync certified monitors are sold for lower affordable prices than a G-Sync certified monitor.
Moreover, in the FreeSync standard, it supports to a specified range of frame rates but Nvidia has no such limitations at any moments. But when picking a G-Sync supported monitor, you’ll only have few different options to continue with. These are the main problems that you’ll face when using FreeSync certified monitor. You can check from the official sites that the monitor you wish to buy has the G-Sync support and the specific range to each model.
In 2019, Nvidia released a driver update that gives the facility to use G-Sync technology in a FreeSync certified monitor. To use the G-Sync technology, both monitor and GPU need to be connected with a display port cable while FreeSync designed monitors works with both HDMI and Display Port Cables. To get the maximum performances, connecting with a display port cable is important in the FreeSync as well.
When we hit G-Sync and FreeSync each other, which adaptive sync is better?
G-Sync is the superior technology from an objective standpoint. But objective standpoint is not the one you are always using. When you are working on a strict budget, FreeSync is the best option for you that can help you to save money and give better performances. But if you have money to afford one of the G-Sync monitors, it will be the best option with its own side features as well. When buying a FreeSync monitor make sure you find the supportive FPS rate according to your model.
