If the action you’re trying to perform is one that requires interaction with the server for it to register-say, opening a loot box that exists for everyone on the server-then network lag might be the culprit of any visible delay. Online games have some things happening ‘client side’ (on your end) and other things happening ‘server side’ (on the game server’s end).

When gaming online, this might mean that your inputs take a while to translate into game actions, because there’s a delay between these inputs and the server registering and processing them or sending the resulting game state back to you for your PC to display. Network lag is when data takes a long time to be sent or received over your network and the internet. Sometimes network lag can be mistaken for input lag, and vice versa. Especially egregious input lag usually has peripherals or the monitor as the culprit, but GPU and CPU processing capabilities and the motherboard’s data transport capabilities can play a part. Finally, your monitor needs to display the new game frame on-screen, and it can only do this when the display ‘refreshes’.Īll of these things happen between you pressing ‘shoot’ and your in-game character visibly shooting on-screen.Īny one of these steps can cause high input lag.Your GPU then needs to store the information in a render queue, render the new game frame, and send it to the display for output.Your CPU must then process this input and instruct the graphics card to render a certain game state based on this new information, which means transmitting the instruction via the motherboard to the graphics card.First, your peripherals must process your input and send this data to your motherboard and then to your CPU.It occurs because there’s a whole chain of things that must happen between your mouse click and your character shooting their weapon. Input lag, also known as ‘system latency’, refers to the time between your peripheral inputs and the corresponding game actions being outputted on-screen.įor instance, if you press your mouse button to make your in-game character shoot their weapon, input lag would be the time taken between the mouse press and your character visibly shooting on-screen.Įveryone has some level of input lag, it’s just that hopefully the latency is so low that it’s imperceptible.
But it’s possible to fix input lag and doing so doesn’t always have to cost an arm and a leg. Perhaps even more frustratingly, there are several things that can cause input lag, making it hard to diagnose. When you’re lining up the perfect headshot only to miss because the game registers your mouse click a second too late, input lag can mean the difference between winning and losing a match. While input lag might not bother you if you’re sitting a few feet from your screen with a gamepad in hand, if you’re playing first person shooters with a mouse and keyboard, it can become a pain very quickly. There are many things that can ruin a gaming experience-low framerates, high network latency, a squeaky chair-but perhaps one of the most common (and most annoying) problems is input lag.
