Windows Sensitivity


At a pointer speed setting of 6/11, for every one mouse count your computer will move the pointer one pixel on your screen, a 1:1 ratio. If the mouse pointer speed it set higher or lower than 6, Windows will artificially modify the mouse input. For instance, at the 7/11 mark, your computer moves the cursor 1.5 pixels for every one mouse count and at the 11/11 mark, your pointer moves 3.5 pixels for every one mouse count. This means that not only does Windows skip pixels, it actually can become impossible for the mouse cursor to land on certain columns. Conversely if you have your slider at the 5/11 mark, your pointer will move .75 pixels for every one mouse count. Since computers cannot show 1.5 pixels, it rounds to either 1 or 2 making uneven mouse movements.
The exact multipliers for these values go as follows:

• 6/11 (default) - 1.00x
  
  
• 1/11 - 0.0625x
  
  
• 2/11 - 0.125x
  
  
• 3/11 - 0.25x
  
  
• 4/11 - 0.50x
  
  
• 5/11 - 0.75x
  
  
• 7/11 - 1.50x
  
  
• 8/11 - 2.00x
  
  
• 9/11 - 2.50x
  
  
• 10/11 - 3.00x
  
  
• 11/11 - 3.50x
  

While a speed setting of 6/11 is the absolute ideal, by keeping it at a even number such as 2/11, 4/11, 8/11 or 10/11 will reduce the impact of Windows' manipulation of the input. This is because the odd numbers have to round. For the highest level of accuracy and least amount of distortion, it is suggested that you keep the pointer speed Setting at 6/11, and then adjust the mouse DPI to find the best sensitivity. Although some players use Windows settings under 6/11, because it has less impact on the mouse accuracy than above 6/11.
