The MarkC Windows 8 + 7 Mouse Acceleration Fix
The 'MarkC Windows 8 + 7 Mouse Acceleration Fix' is available for download from this link:

For help for the fix, visit the ESReality MarkC Windows 7 Mouse Acceleration Fix page:

What is it?

It is a registry file that removes Windows 7 or 8 mouse pointer acceleration.

It is like the CPL Mouse Fix and Cheese Mouse Fix, but gives exactly 1-to-1 mouse to pointer response for Windows 7 or Windows 8.

Exactly 1-to-1 means no discarded or delayed mouse input while game playing.

How do you use it?

Find the display DPI that you currently use:
Click Start, click Control Panel, select Appearance and Personalization, select Display.
See if you have 100% or 125% or 150% selected.

Open the ZIP file at the link above.

Select the folder that matches the Windows version you use and Double-click it.

Select the REG file that matches the DPI% you use and Double-click it.

Answer Yes, OK to the prompts that appear.
(See below for non-Administrator account use.)

Reboot or Log off to apply the fix (you have to reboot or Log off).

Enjoy exactly 1-to-1 mouse to pointer response!
(If you applied one of the Windows 2000 or Windows 98/95 Acceleration fixes, then 'Enhance pointer precision' must be checked ON to enable it.)

Why do you need the fix?

If you don't know you need it, then you don't need it!

Some older games, such as Half-Life 1, Counter-Strike 1.x, Quake, Quake 2, Unreal and others, while they are active and running, call a Windows function intending to disable variable mouse acceleration by forcing ALL movement to be accelerated by the same amount (doubled).
On Windows 2000 and earlier, that removed all variable acceleration.
Pointing and aiming in those games was OK, because the mouse response was then linear (all movement was accelerated by the same amount; it was doubled).

In XP, Vista, Windows 7 and Windows 8, Microsoft changed how mouse pointer acceleration worked.
Now when those games call the function (asking that all movement be accelerated), Windows enables the mouse 'Enhance pointer precision' feature, which adds mouse acceleration using a varying curve to control the mouse response. (It enables it even if you have it turned off in the Control Panel Mouse settings.)

With 'Enhance pointer precision' enabled, slower mouse movements make the pointer go extra slow and faster mouse movements make the pointer go extra fast. It is not linear and not straightline.

This is annoying, because where you are aiming at depends on how far you move your mouse, and also on how fast you moved the mouse to aim.

How does the fix work?

It redefines the curve used by the 'Enhance pointer precision' feature to be a completely straight line. The slope of the line is tuned so that every on-mouse-pad mouse movement is turned into exactly the same amount of on-screen pointer movement.

How do you know the fix is working?
