Corsair NIGHTSWORD v2 Wireless SD: Specs, Price, Pros & Cons
The NIGHTSWORD v2 Wireless SD is the first gaming mouse with a dedicated Stream Deck button, and that button is the reason it exists. Pressing it (a separate key on the left flank marked with the Elgato logo) opens the Virtual Stream Deck, an on-screen panel of shortcuts you fill from the Stream Deck app: macros, scene changes, Discord mutes, in-game actions, Marketplace plugins. No physical Stream Deck is required. Corsair's own FAQ confirms the mouse itself counts as the supported device, provided you run Stream Deck software 7.0 or later.
The rest is a competent ergonomic mouse. Corsair's MARKSMAN S optical sensor runs to 33,000 DPI with 750 IPS tracking and 50 G, on optical switches rated for 100 million clicks. Polling runs far above the usual ceiling over both USB and the SLIPSTREAM 2.4 GHz link, though Corsair notes the mouse ships at the ordinary rate, that reaching the top of the range depends on your processor, and that Bluetooth does not support it at all. Connectivity is tri-mode, and the box includes a receiver plus an adapter dock so you can park it beside the mouse.
The shape is right-handed with a thumb rest, 129.6 by 78 by 40.9 mm, 89 g, on virgin-grade UPE skates, with a tilting wheel for horizontal scrolling and five sensitivity stages. Configuration does not use iCUE: this mouse is set up through Corsair's browser-based Web Hub, which handles sensitivity, macros, polling, lighting and firmware.
Unlike the original NIGHTSWORD, which shipped with a tray of tuning weights, this model has no adjustable weight system at all. Corsair states a single fixed figure and there is nothing to add or remove. Anyone upgrading from the first version specifically for that feature should know it is gone entirely.

How this VS Score was computed
Score 70: each known spec is measured against the median of all mice (81 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 77% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
This is a mouse for one kind of person: someone who already runs Elgato's Stream Deck setup, or wants to, and keeps reaching for shortcuts mid-game or mid-stream. If that is you, having the Virtual Stream Deck a thumb-press away is useful and costs no desk space. Anyone who has never wanted a Stream Deck is paying for a button they will remap to something ordinary.
The first thing to set is the polling rate. It ships at 1,000 Hz, and 8,000 Hz is opt-in for good reason: it wants CPU headroom and it cuts battery life from 42 hours to about 25 with the lighting on. On a high-refresh monitor the difference is real but small, and most people should leave it at 1,000 or 2,000.
The second is lighting. Corsair's headline 170-hour figure is lights-off, and the gap between that and the lights-on figure is wide. Decide early which you want, because it changes ownership completely.
Configuration through the browser-based Web Hub, with no iCUE involved, is a real improvement if you have ever fought with Corsair's desktop software, though a few settings (lift-off distance, Motion Sync, ripple control) are described as arriving rather than shipped, so check they are live before relying on them.
It is not a featherweight, and the palm-oriented shape with a thumb rest suits long sessions more than flick-heavy shooters. Bought for what it is, a comfortable mouse with a shortcut panel attached, it is a sensible thing to own.

The bottom line
The Corsair NIGHTSWORD v2 Wireless SD earns a VS Score of 70, above the median of the 81 mice it is measured against (a score of 50 is level with that median).
- Who it’s for
- Streamers and multitaskers already on Elgato's Stream Deck setup who want the Virtual Stream Deck one thumb-press away, on a comfortable palm-grip body.
- Who should look elsewhere
- Flick-heavy shooter players who want low weight, and anyone who will never use the Stream Deck button, because that is what the price buys.
- The trade-off that matters
- A novel shortcut panel, against a palm-first shape heavier than a competitive shooter mouse and a headline battery figure that only holds with the lighting switched off.
- The main alternative
- Logitech MX Master 4, if the appeal is productivity shortcuts rather than gaming: a haptic thumb panel, far longer battery, and no Elgato dependency.
