来源:百度知道 编辑:UC知道 时间:2024/06/18 18:01:45
我的系统是XP SP3
我的鼠标的刷新率能达到500HZ~但是SP3的USB默认刷新率是125HZ
玩游戏时有点不爽~~在网上搜索了半天(所有方法都不行)~
哪位大大知道解决办法,谢谢了~~希望写详细点~~非常感谢~~
PS;那些没有试过的人就不要回复了~~因为本人已经试过N次了~~
回答的好的我会加分~~

我的系统是XP SP2,所以我没试过(试了对你也不能照搬),但我觉得是可行的。有中文和英文的参考,英文的有新的东西,也很值得参考。

正文(要改两个目录下面的驱动文件):
To do this, you need to use a hex editor (xvi32) and edit the file in Safe Mode. Not only do you edit usbport.sys in C:\WINDOWS\system32\drivers, but you must also copy the patched file into C:\WINDOWS\system32\dllcache (hidden by default, edit your folder options to reveal protected OS files).

Once you've got the patched usbport.sys in both the drivers/ and dllcache/ directories, reboot and you're good to go.

To check your mouse polling rate, use the dx_mouse_timer_dialog
