What software do I need to install to change the settings of my Razer Basilisk Ultimate?
To change the settings of your Razer Basilisk Ultimate – including customizing key binds, lighting, macros and other functions, please download and install Razer Synapse 3.
What is the clutch for?
Deliberately shaped like a clutch rather than a traditional button, the easily accessible clutch is designed not only to actuate and release quickly but also for enhanced comfort when held down; as opposed to traditional buttons that are intended for quick click-and-release. Push-to-talk, temporary DPI adjustment and other game actions that require the gamer to hold down the mouse button can now be executed in greater comfort. The clutch’s default setting is to adjust the DPI to 800 when held down. A rubber cap is also included for gamers who prefer not to use the clutch. Like other programmable buttons, the clutch can be customized in Razer Synapse 3.
What is the dial at the bottom of the mouse?
Designed specifically to cater to FPS gamers who bind game actions to their scroll wheel, the Razer Basilisk comes with a range of customizable scroll wheel resistances to choose from. Using a dial on the bottom of the mouse, FPS gamers will be able to set the scroll wheel at their preferred resistance level for activation of bunny hops, weapon selection and more.
