Generally, a polling rate of around 500 Hz is considered substantial for gaming across mice and keyboards. On the other hand, too low polling rates will reduce your input accuracy. Increase in extreme polling rates such as 1000 Hz will only make the computer (PC or console) work harder in keeping tabs on the device and may increase input lag instead of reducing it. Now, you may think that higher polling rates will reduce input lag, but that is not generally the case. ![]() Where a mouse reports on its position, a keyboard reports on the key presses made just as a controller or joystick. The polling rate is the number of times an input device reports the inputs made on it to the computer. There are two reasons that might cause input lag from these devices – Polling rate Input lag is most common across mice and game controllers although you may face the same with your keyboard as well. The second possible cause of input lag can be the medium for providing input commands or instructions, i.e. Read on and you will find a lot more input lag adding to the already obvious 20ms display lag. It May not seem much, but 20ms is a huge margin in esports or competitive online gaming. Add this to the hardware-end input lag, a few more milliseconds, you get around 20 milliseconds of input lag already. Now understand that at 60Hz, you get one new frame displayed every 16.67 milliseconds (1/60 = 16.67.) That is your inherent display lag. ![]() It will obviously take some time for your console or PC to render the required graphics and some more for your monitor or TV to display it. Know that there is nothing like 0 input lag. Without these refinements, you are sure to face some form of lag. High-end displays come with inbuilt tech that enables them to perform functions such as upscaling, motion, or edge smoothing. This is caused solely by your display or monitor. In display terminology, input lag is known as output lag. So, here is a complete explanation of every type of input lag you might be facing! 1. Frames per second or FPS is the number of frames rendered by your gaming console or PC.īut displays are not the only reason you might be facing input lag although it is the most common cause. The refresh rate is the number of times your monitor or TV refreshes with a new displayed frame every second. Although the human eye is not capable of detecting these static images or frames, you will surely notice ‘smoother’ video quality with higher refresh rates. At max resolutions, frame rates may be further reduced.ĭisplays show you several static images in a second. Note that this will also depend on the resolution. With a 60Hz monitor, you get 60 frames per second at max. Input lag is most common on low refresh rate displays, where the screen displays a low number of frames every second. The results may be as simple as missing the kerb on FIA GT or getting killed on COD Warzone even after you take the shot first! You may left click to shoot or press left to steer, but the input is registered too late. ![]() With input lag playing its part, you may see your target much later than when the target was originally simulated. Input lag is the time delay when the action happens on screen and the moment it is visible you or you get to react to it. Although troubleshooting cannot make your display show higher frames per second, it can easily root out other possible causes. Professional gamers and esports aficionados swear by devices with the lowest possible input lag and so should you!Įven an amateur gamer can easily diagnose input lag and use basic troubleshooting to reduce it. Input lag can be a detrimental factor, especially in multiplayer games high on action and on FPS requirements. It is a time delay of milliseconds in displaying frames or actuating actions, gifting your competition the winning edge. ![]() Input lag is one of the most annoying issues for gamers.
