4. CONFIGURING YOUR RAZER LACHESIS
RAZER SYNAPSE ONBOARD FUNCTIONS
MAIN WINDOW
All settings will be saved on the profile selected and will apply on another computer even without the
Razer Configurator installed. (Note: On-The-Fly Sensitivity requires the Razer Lachesis driver to be
installed)
ASSIGN BUTTONS TAB
In the Assign Buttons tab, you can assign various functions to each of the buttons based on your own
preferences.
The following functions are possible:
Click
Perform a left mouse click.
Menu
Open a context-sensitive menu.
Universal Scrolling
Click once on the assigned button to activate universal scrolling. Drag your Razer Lachesis to scroll in the
direction of the mouse movement.
Double Click
Perform a double click with the assigned button.
Macro
If the button function or key is not listed, or if you would like to assign a macro to a button, select
“Macro” from the dropdown menu. In addition, all saved macros will be shown on a sub dropdown
menu for quick selection when you mouse over the “Macro” option.
Sensitivity Stage Up
Switch the current sensitivity stage to the next stage.
Sensitivity Stage Down
Switch the current sensitivity stage to the previous stage.
Profile Settings
Switch to a profile on the fly and immediately load all your pre-configured mouse settings.
When you select “Profile Settings” from the dropdown menu, a sub-menu will appear that allows you to
choose your desired profile.
Forward
Assign a “Forward” command in Windows Explorer / Internet Explorer.
Backward
Assign a “Back” command in Windows Explorer / Internet Explorer.
On-The-Fly Sensitivity

Single Key

Scroll Up
Scroll up the page you are currently viewing.
Scroll Down
Scroll down the page you are currently viewing.
Button Off
Disable any function on the assigned button.
ADJUST PERFORMANCE TAB
Current Sensitivity
Sensitivity is how much your cursor moves on the screen in relation to your physical movement of the
mouse. A higher sensitivity value would translate to less physical movement of the mouse, and vice
versa.
In the ADJUST PERFORMANCE tab, the current sensitivity of your Razer Lachesis is indicated in dots per
inch (DPI) and can be easily adjusted by moving the arrow along the slider in steps of 100DPI and up to
5600DPI. To set a different sensitivity level in the X and Y axis, you can select the “Enable independent X-
Y sensitivity” option and move the individual X and Y arrows along the slider. To display the On-The-Fly
Sensitivity indicator onscreen whenever you make changes on the fly, select the “Enable On-The-Fly
sensitivity on-screen display” option.
Acceleration
Acceleration is an internal filter of the driver, and is primarily a legacy option for low dpi mice users.
With acceleration enabled, the faster you swipe the mouse, additional movement is added. Windows XP
has acceleration turned on by default as a convenience for users assuming that everyone will have
400dpi mice, but this will likely be a hindrance to most gamers and precision users who require greater
accuracy. The ‘acceleration off’ option (default) turns off internal acceleration only and does not affect
Windows XP acceleration, which can be turned off via the Control Panel, Mouse, Pointer Options, and
unselecting ‘Enhance Pointer Precision’. You can activate acceleration by checking the “Enable
Acceleration” box and moving the arrow along the slider.
Polling Rate
The polling rate determines the time intervals that the PC retrieves data from your mouse. A higher
value would mean shorter intervals and therefore less latency. You can switch between 125Hz (8ms),
500Hz (2ms) and 1000Hz (1ms) by clicking on the individual polling rate buttons.
MANAGE PROFILES TAB
A profile allows you to store your various mouse settings such as sensitivity, button assignments and
macros as a single group for your convenience. In addition, you can also set your Razer Lachesis to
change profiles once a particular program is launched.
In the Manage Profiles tab, you can create and activate customized profiles based on the application you
have launched.
a. Profile: Indicates the profile number
b. Profile Name: Double-click this field to enter a profile name of your choice.
c. Application: Double-click this field to open up directory browsing. Select the executable file of the
program you want the profile to be linked to.
d. Auto Switch: Check the box to enable automatic profile switching when the chosen application is
launched.
