Turn your mouse from a salad dodger to Premiership player titan.
1) The first task is to find out how fast you optical mouse currently is. Use the Mouse Rate Checker (which you will need to download) found at
http://tscherwitschke.de/download.html . When you run it you should be getting a result between 100Mhz and 260Mhz, hopefully we can increase this.
2) Next job is to download and install USB Mouserate Switcher found at
Softpeida . Now reboot into Windows Safe mode and log in as the administrator rather then a limited user account. Once your in run the app then click Patch to begin the black magic.
3) The software should give you three overclocks to windows default of the 125Mhz/8ms USB polling rate. The first 250Mhz/4ms is a safe overclock but as mentioned before isn’t that great. The 500Mhz option should suit most users while the 1000Mhz is unstable and isn’t much use to anyone, so 500 Mhz is your best bet.
4) This step is important so read carefully! Unplug all your USB devices EXCEPT the mouse and reboot back into XP. Load up Mouserate and you should find you mouse is now a lot more responsive. Now plug back all your USB devices one by one testing each one still works, If it doesn’t repeat step 3 but pick 125Mhz.
I can't imporve your ping rate but the extra speed should give you better response and better snipping in results Counter strike Unreal et al.
