How to: Improve mouse response/accuracy by changing the USB polling rate

Windows Vista & 7 64-bit


Windows by default has the usb ports working at 125Hz of 1000Hz that USB is capable of, giving 8ms response times. You can change the frequency to 250Hz(4ms), 500Hz(2ms) and 1000Hz(1ms) to get better response times. These files will increase your USB polling frequency from the Windows Vista default of 125hz to 500hz or 1000hz making your mouse much more responsive in gaming.

1. What you need: HIDUSBF.zip - dimr.exe (Direct Input Mouse Rate)

2. Extract HIDUSBF.zip & dimr.exe into a folder

3. Right click on "HIDUSBF.INF" find install


4. Open HIDUSBF folder and click on "Setup.exe"

5. Find your mouse click on it (it should be highlighted has blue) and at the bottom of the window check "Filter On Device" and select your Rate





6. Click Install Service and Restart. Open up dimr.exe, if it's still runs default 125hz reboot your windows Vista or 7 64-bit operating system again.



Some Mouse wont go up more than 300Hz.
