It would be convenient to have the option to turn this off in the game settings. It is on by default.

I know this is an old post but you still haven’t responded. Then why is there a bDisableMouseAcceleration=False then in the GameUserSettings.ini?

That config setting is routed into this Mac only CVar, and has absolutely no impact on PC:

static FAutoConsoleVariableRef CVarMacDisableMouseAcceleration( TEXT("io.Mac.HighPrecisionDisablesMouseAcceleration"), GMacDisableMouseAcceleration, TEXT("If set to true then OS X's mouse acceleration curve will be disabled while using high-precision mouse mode (typically used when games capture the mouse) resulting in a linear relationship between mouse movement & on-screen cursor movement. For some pointing devices this will make the cursor very slow. (Default: False)"));

The comment about the no-acceleration mode sometimes dramatically changing the speed of input is why it exists for Mac, otherwise it wouldn't exist anywhere.
