How to play overclocking with normal mouse under Windows 7

CS and other FPS games, the requirements of the mouse is relatively high, although there are many professional game mouse, with ultra-high dpi and refresh frequency, but the price is higher. For many game enthusiasts who use ordinary mouse, there is no way to improve the performance of the mouse, so that ordinary mouse can get a better game experience it? Let's take a look at how to overclocking a normal mouse in Windows7.

Tip: The most important two indicators of the mouse: DPI and refresh frequency. The DPI is the number of dots per inch, which is the number of dots per inch the mouse moves on the screen, and the higher the DPI, the more accurate the positioning. Refresh frequency is mainly refers to the mouse interface refresh frequency, the current USB interface refresh rate is 125HZ, can not meet the high DPI mouse data transmission requirements.

Ordinary mouse dpi mostly in between 400-800, this is not changed, so we have to do is to improve the mouse refresh frequency, we can first use mouserate this software to test the mouse refresh rate, the average mouse value will be less than 125HZ, so it is necessary to overclocking.

The first step: first find the system in the partition of the windowssystem32drivers under the Usbport.sys this file, and then copy to any directory backup, so as to avoid problems can be restored.

Tip: The overclocking method is only valid for USB interface mouse

Step Two: Right-click Usbport.sys, select Properties, select Security-Advanced, click Edit in the owner setting to change the file authorization to administrator, and then click "Change Permissions" in the "permissions" setting to include permissions that can be inherited from the object's parent. The administrator is then given full control.

Modify Permissions

Step three: Right click on Usbport.sys, choose Open Mode to open with UltraEdit, click "Search", find "3C C6 83" This string, and then change this string to "B0 8A", after modification, Overwrite the original Usbport.sys file with the modified file and restart the computer.

Fourth step: Again run mouserate software, you can see the refresh rate has become about 360HZ, and then play the game, is not feel the mouse more flexible?
