Software

The DeathAdder V3 is fully compatible with Razer's modular software, Synapse 3. Synapse is embedded into an overarching software suite called Razer Central. From there, it is possible to install additional optional modules, such as Chroma Connect, Chroma Studio, or the highly sophisticated macro editor.

All settings are accessible through three tabs. "Customize" houses button remapping, which also includes a HyperShift function to enable a second set of button maps that can be accessed upon pressing a dedicated shift button. "Performance" is used to adjust CPI for up to five levels, ranging from 100 to 30,000 CPI and in increments of 50. Polling rate can be set to 125, 500, 1000, 2000, 4000, or 8000 Hz. "Calibration" allows one to adjust the lift-off distance between three presets (low, medium, high), along with the option of setting up asymmetric cut-off. Lastly, profile management is available, too.

All setting changes are applied immediately and saved to the on-board memory, so the software does not need to be running (or be installed) all the time. On my system, Synapse had a RAM footprint of 379 MB on average when running in the foreground, which doesn't change when minimized, be it to the taskbar or system tray. Upon exiting the application, several processes with an overall RAM footprint of 200 MB keep running. Remarkably, these processes continue to load even if Synapse is set to not auto-start with Windows. The most convenient way of terminating these processes is to run any recent Razer mouse firmware updater.
