![]() If I doubled the mouse dpi, I would need to scale the X and Y values by 2 to achieve a similar feel. Most people that argue against mouse acceleration use inconsistent flicks as the basis of their argument, but most of them only have experience with 1 preset curve. This helps to make flicks more consistent. I want the curve to quickly taper off towards a more linear shape so that there is little change in effect during medium to faster motions. This curve is designed around the idea that the mouse acceleration should be felt only at lower speeds to give extra precision with slower movements. There is alot of discussion about what makes a good curve in the links posted. Values might vary widely from person to person because of personal preference along with system settings. If you have Windows 7, then OS_DPI_Factor is 96 / 150, and CPL has a final sensitivity of 4.24 × (96 / 150) / 3.5 = 0.775. If you have XP or Vista 60Hz, then OS_DPI_Factor is 60 / 96, and CPL has a final sensitivity of 4.24 × (60 / 96) / 3.5 = 0.757. Windows 8 = Desktop_Text_Size_DPI / 120Ĭontrol_Panel_Pointer_Speed_Slider_Factor is the "Sens Factor (EPP ON)" column below: Windows 7 = Desktop_Text_Size_DPI / 150 XP+Vista = Monitor_Refresh_Rate / Desktop_Text_Size_DPI Notice for that every pair of numbers, Curve Sensitivity = y/x = 4.24, and because EVERY pair has the same ratio, CPL has no accel and a constant sensitivity at all speeds.įinal Windows sensitivity is = Curve_Sensitivity × OS_DPI_Factor × Control_Panel_Pointer_Speed_Slider_Factor / 3.5. although the final decimal places on the y values might be a bit wobblier (but the final decimal places don't matter too much). If you're trying to achieve a perfect 1:1 ratio of counts to pixels, see this thread: You can also remove mouse acceleration for older games that automatically enable it (such as quake 2) by entering a linear graph similar to:Ī steeper slope means higher sensitivity. The Y value represents how much the cursor moves in response. The X value of a point represents how fast you move the mouse. The user can select the next 4 points to create the curve: ( 0, 0) is the first point and is implied. The acceleration curve is interpolated/extrapolated from 5 points on the coordinate system. and hoppan for sharing the necessary info.ĭefault settings for Windows 7/XP/Vista and Windows 8 can be loaded from the 'File' menu. Attached is a small program for creating custom mouse acceleration curves in Windows.
