Overview

Pulsar Fusion is configuration software for Pulsar gaming mice, with separate versions for wireless mice and newer wired models. It suits Pulsar owners who want to adjust controls and sensitivity; its main drawback is that the correct software and some features depend on the mouse model.

Wireless Fusion supports Pulsar wireless mice except the eS Series, while Fusion2 wired software supports wired Pulsar mice released after September 2024. Pulsar also lists Fusion2 for newer wired and wireless models, so check model compatibility before downloading. Some models handle firmware updates within the software. Pairing a 4K dongle requires Fusion and the 4K Wireless Pairing tool; the tool does not work with eS series dongles, for which Pulsar directs owners to support. Fusion can restore default mouse settings from the button assignment tab.

Key features

Profiles, DPI and controls

Windows users can create multiple settings profiles and import or export settings files, which is useful for keeping distinct configurations. Up to three DPI profiles can be configured, alongside button customization and lighting control. The Xlite CrazyLight software listing also includes firmware updates and macro settings.

Macros and polling

Windows Fusion can record advanced macros and assign them to mouse buttons. It cannot add scroll-wheel movement to those macros; that requires the compatible web driver. This limitation matters for users whose macros depend on wheel input. 4K and 8K polling require both a compatible mouse and the corresponding receiver or dongle, so the software alone does not unlock those rates.

Turbo Mode

Turbo Mode locks the sensor at a 20,000 FPS scanning rate and is beta-available for CrazyLight, TenZ and X2F models. It increases battery demand, making it a trade-off for supported wireless mice rather than a free performance gain.

Pricing

Pulsar Fusion is free, with a free plan and no paid tier identified. That makes it a straightforward choice for owners of supported Pulsar devices who need configuration tools, but it is not a general-purpose peripheral suite for users of other brands.

Platforms

The Windows desktop software supports profiles and advanced macro recording, but it is not compatible with macOS. Newer compatible models can use Pulsar's web software in a browser; the Xlite CrazyLight listing calls its web version Bibimbap and also offers PC software. Although Windows, macOS, Linux and web are associated with the entry, the specific features depend on the version and device. Confirm compatibility rather than assuming every platform supports every mouse.

Who it's for

Fusion is best for Pulsar mouse owners who want to remap buttons, adjust lighting and DPI, or maintain multiple Windows profiles. It is less suitable for eS wireless owners seeking Fusion compatibility, Mac users relying on the Windows app, or anyone who needs wheel movement in Windows-recorded macros. Buyers should also account for the receiver and compatible mouse needed for 4K or 8K polling.

Pros and cons

Pro: Multiple Windows profiles with import and export help preserve or switch between configurations.
Pro: Up to three DPI profiles, button customization and lighting control cover core mouse adjustments.
Pro: Advanced macros can be recorded and assigned to buttons in Windows.
Con: Wireless Fusion excludes eS Series mice, and Fusion2 wired support is limited to mice released after September 2024.
Con: Windows macros cannot include scroll-wheel movement without the compatible web driver.
Con: Turbo Mode raises battery demand, and high polling rates need the matching receiver or dongle as well as a compatible mouse.

Alternatives

Razer Synapse is a free option for readers seeking peripheral software with Windows, macOS and web platforms. ROCCAT Swarm II is free device configuration software for compatible Turtle Beach devices, with Windows, Android and iOS support.

MonsGeek Driver offers free keyboard driver and configuration downloads for supported models, with macOS, web and Windows platforms. Choose it for a supported MonsGeek keyboard rather than a Pulsar mouse. 8BitDo Ultimate Software V2 is free for supported 8BitDo devices on Windows 10 (1903) or above and macOS 13.0 or above.

Glorious CORE is free software for configuring most Glorious products on macOS and Windows; cloud profile saving requires a Glorious ID. Logitech G HUB is another free macOS and Windows option, with LIGHTSYNC RGB customization, device configuration, presets and game profiles.

Elgato Wave Link is free on macOS and Windows for microphone and audio-interface users, with no subscription or feature gates. SteelSeries Moments is a Windows alternative. For broader category browsing, see Gaming Peripheral Software and Keyboard and Mouse Customization Software.

Verdict

Pulsar Fusion is the right free choice for owners of compatible Pulsar mice who want practical control over buttons, DPI, lighting, profiles and macros. Its model-specific compatibility, Windows-focused feature set and macro limitation are good reasons to look elsewhere if your device or workflow does not fit those boundaries.
