aim/look sensitivity, you probably noticed that by moving slowly you rotated 360 degrees or more with
a short swipe, but by moving very fast you rotated only a short distance. That poor movement you just
experienced is NOT mouse lag, but rather the game's turn speed limit.
The easiest way to understand what is happening is to equate the maximum turning speed to
distance turned (rotated) in a period of time. For example, let’s say with the aim/look thumb stick fully
engaged it takes our game one full second to perform a 360° rotation, that would make our game’s
maximum turning speed equal to one rotation per second. Now to illustrate how that pertains to our
mouse, let’s say that with our current KeyMander profile moving the mouse four inches in one second
performs a full rotation; it would mean our max turn speed with the mouse is 4 inches per second.
Now here is where the turn speed limit begins to show up with a mouse: if we move 8 inches in one
second (double the limit in our example), the extra movement above the maximum turn speed is not
registered and it’s as if you moved for only half the distance or half the time (equal to a half rotation
for our example). Following the same formula if we move it 16 inches (four times the limit), your on-
screen aim/look view moves only a quarter of the time/distance (equal to a quarter rotation for our
example), and so on. Simply put, once you hit maximum turn speed, the faster you move the mouse,
the slower you go. Unlike on a PC, using a mouse in an environment designed for a joystick also
requires getting used to playing within the game’s turn speed limitation, but it’s a small trade-off for
being able to play console games with a mouse and keyboard and it's easy to set up your KeyMander
profiles to work within this limitation.
Turn Speed Setting (K2 App)
One way to overcome the turn speed limitations built into some games is through the use of the K2
App’s Turn Speed setting, which progressively adds acceleration to boost your aim/look speed the
faster you move. Slower movements stay slow and precise, but quick movements ramp up the turn
speed to make spinning around much easier in games with lower turn speed limitations. Acceleration
is usually avoided by most PC gamers since noticeable turn speed limitations are rare in PC games,
however some console game designers understand that acceleration can be beneficial at times, and
have begun adding the option in some games. TitanFall 2 is a one example, having programmable
acceleration levels and curves in the game’s settings menu. The K2 App also has programmable
mouse response curves to add similar functionality to games without these adjustments. When
setting up your game profiles, remember to treat acceleration like salt at the dinner table; it’s there if
you need it, but if it’s already good you probably shouldn’t add anything or you could end up making it
worse.
Deadzone Setting (K2 App and In-Game Options)
If you are having problems with getting a smooth response from the mouse, especially when moving
diagonally, take a look at the DeadZone setting. The Deadzone’s primary function is to overcome the
area of the controller where joystick movement does not register in-game and allow instant response
from the mouse, but when improperly adjusted it also influences mouse movement in a negative way.
Having the deadzone set too low will cause choppy mouse response as initial mouse movements or
