Win 7 mouse can also play overclocking

CS and other FPS games, the requirements for the mouse is relatively high, although there are many professional gaming mice, with super high DPI and refresh frequency, but the price is also high. For many game enthusiasts who use ordinary mouse, is there any way to improve the performance of the mouse, so that the ordinary mouse can also get a better gaming experience? Let's take a look at how to overclock an ordinary mouse in Windows 7.

Tips: The two most important indicators of the mouse: DPI and refresh rate. DPI is the number of dots per inch, which is the number of points the mouse moves on the screen for every inch of movement of the mouse. The higher the DPI, the more accurate the positioning. The refresh frequency mainly refers to the refresh frequency of the mouse interface. Currently, the refresh frequency of the USB interface is 125HZ, which cannot meet the data transmission requirements of the high DPI mouse.

The DPI of ordinary mouse is mostly between 400-800. This can't be changed, so what we have to do is to increase the refresh rate of the mouse. We can first test the mouse refresh with mouseerate. Rate, the average mouse value will be lower than 125HZ, so it is necessary to carry out overclocking.

Step 1: First find the usbport.sys file under WindowsSystem32drivers in the partition where the system is located, and then copy it to any directory backup to avoid restoration when there is a problem.

Tips: Overclocking method is only valid for USB mouse.

Step 2: Right click on usbport.sys, select Properties, then select Security - Advanced, in "Owner" Click Edit to change the file authorization to Administrator, then click on “Change Permissions” in the “Permissions” setting to search for permissions that can be inherited from the object's parent, and then give the Administrator full control.

Step 3: Right click on usbport.sys, select Open as Open with UltraEdit, click on “Search”, find the string “3C 08 73 09 C6 83”, then change this string to “B0 01” 73 09 52 8A", after the modification, overwrite the original file with the original usbport.sys file and restart the computer.

Step 4: Run the mouserate software again, you can see that the refresh rate has become Around 360HZ, after playing the game, do you feel that the mouse is more flexible?
