Sitting in front of the computer, starting to handle it and checking that the mouse does not respond to us immediately as it should, is something especially annoying, and although it may be due to a hardware problem, it is normal that it is mainly a problem related to the software that makes the system not allow the movement of the mouse or does it with a certain latency.
What is mouse lag and what causes it
When we talk about lag when using the mouse we are referring to that delay that occurs with the movement of the pointer that is not done in synchronization with the movement of our hand. It also happens that the clicks with the right or left button are slower or that the pointer freezes and we cannot move it. We can find different problems caused with lag, such as:
- Problems during the execution of video games, capable of ruining any game.
- We find problems in our productivity if the pointer does not move smoothly, so completing our daily tasks can become quite an odyssey.
- Problem with mouse locks when not responding to our prompts
- The buttons do not react so our mouse loses effectiveness.
It should be noted that these problems can occur both in the use of wired and wireless mice. These problems can have their origin in different causes, such as the drivers of the mouse itself, the Windows Fast Startup or the power manager. Likewise, the battery or the connection port can also be the cause of this annoying problem.
Troubleshoot mouse latency
Next, we are going to see a series of measures that we can perform on our Windows 10 computer in the event that we have latency or lag problems with our wired or wireless mouse.
Check the battery and connection ports
In the event that we have a wireless mouse it is important that the first thing we do is check the status of your battery or batteries. In the event that these are worn or in low levels of charge, it is possible that it ends up affecting problems of slowdowns or blockages during use. Therefore, we must turn the mouse over, slide the cover and replace the battery to see if it is the cause of the problem.
If we use a mouse wirelessly, the problem is derived from the connection ports. Computers generally have USB 2.0 and USB 3.0 ports, so the mouse may not support the speed of the port. Therefore, we must locate the USB ports, and once we know what the USB 2.0 port is, we connect it and restart the PC.
Check your mouse drivers
Usually Windows is responsible for installing generic drivers for our mouse. These may not be updated frequently, so it can cause us problems at any time. Therefore, we must check if there are new updates available and in that case proceed to install them.
To do this, press Windows + X and select the “Device Manager” option. Once the window appears, we go to the “Mouse and other pointing devices” section. We unfold it and click with the right mouse button and select «Update the driver»Within the context menu options. Once Windows installs any recommended drivers we restart the computer to see if the problem has been solved.
Disable scrolling through inactive windows
Windows has a function that allows us to move around inactive windows when we pass the mouse pointer over them. This function can cause problems with the mouse, so we can try to disable it.
To do this we are going to press the keyboard shortcut “Windows + I” to access the Settings menu. Here we click on “Devices” and in the left column we select the “Mouse” section. Now we should see an option called “Move inactive windows”, so we will click on the button to deactivate it. Later we restart the system and check if the problem persists.
End the Realtek Audio process
Another option that might work to fix our mouse lag issues is to disable the Realtek Audio process. To do this, we right-click on the taskbar and select Task Manager. We make sure to find ourselves in the “Process” tab and go to the “Background processes” section.
Here we must look for the option “Realtek HD Audio” and click on it with the right mouse button. We click on the “End task” option and check if the problem has been solved.
Disable Windows Quick Start
Fast Startup or Quick Start is a Windows 10 functionality specially designed to start the PC faster than usual. This has a handicap and is that the system does not shut down correctly, which can lead to problems with the mouse. Therefore we can try to disable this feature.
To do this we must write control panel in the search box of the Start menu and select it from the list. Once it appears we must organize by small icons and select the “Power Options”.
On the left side we select “Define behavior of the start / paid buttons” and then “Change the configuration that is currently not available”. We scroll to the bottom and uncheck the box “Activate fast startup and restart the computer.”
Change power manager options
We can also try to change the mouse power management options so that Windows 10 does not turn it off to save energy. Sometimes it may not work correctly when you turn it off and on again, appearing the dreaded lag.
Therefore, we use the shortcut “Windows + X” to access the “Device Manager”. We go to the “Mouse” and other pointing devices section and double-click to open its configuration and click on the “Power Manager” tab. Here we uncheck the “Allow the computer to turn off this device to save energy” box. Finally, we restart the PC and check if it has solved the problem.
