Corsair shows off gaming mouse with dedicated Stream Deck launch button — wireless mouse also gets almost 50 hours of 8K battery life
Corsair showed off its new Stream Deck-integrated gaming mouse at Computex 2026— the Nightsword v2 Wireless SD Stream Deck gaming mouse. This mouse is semi-unique in that the Stream Deck app detects it as part of the Stream Deck ecosystem, which means you can map Stream Deck features directly to the mouse's 8 programmable buttons. It also features a dedicated Stream Deck Launch button, which lets you open up a Virtual Stream Deck (e.g. a Stream Deck on your screen) and activate Stream Deck functions from said "VSD."
This means the Nightsword v2 Wireless SD is more than just a mouse with macro-programmable buttons — not only do you get access to the Stream Deck's wide range of integrated plugins (mostly for various streaming and gaming platforms — it is called a Stream Deck for a reason, after all), but you can also program Stream Deck functions such as "multi-action," which lets you set up multiple Stream Deck actions to be performed in a sequence. It's great for people who want a one-click way to access their streaming or gaming setup.
Of course, the Nightsword v2 Wireless SD isn't the first gaming mouse with Stream Deck integration — Corsair's Scimitar Elite Wireless SE also featured native Stream Deck integration that allowed for both Stream Deck programmability and access to Virtual Stream Decks. However, instead of having a dedicated Stream Deck button, the Scimitar Elite Wireless SE just kind of had Stream Deck functionality built-in as a bonus (although, as a mouse with a 12-button side panel, it perhaps had more of an argument for the programmability).
Specs-wise, the Nightsword v2 Wireless SD features 11 buttons (8 of which are programmable) and sports Corsair's Marksman S optical sensor, which has a maximum sensitivity of 33,000 DPI and a maximum speed of 750 IPS, and can handle up to 50 G's of acceleration. This is the same sensor we've seen in Corsair's other recently-launched mice, including the Sabre v2 Pro Wireless CF and Sabre v2 Pro Wireless MG as well as last year's Scimitar Elite SE. It has a sculpted, right-handed ergonomic design that measures 5.1 x 3.07 x 1.61 inches (129.6 x 78 x 40.9mm) and weighs 3.14 ounces (89g). The primary mouse buttons have optical switches, which are rated for up to 100 million clicks.
The mouse features 2.4GHz wireless, Bluetooth, and wired connectivity, and has up to an 8,000 Hz polling rate over its 2.4GHz wireless connection. It gets up to 170 hours of battery life over its 2.4GHz wireless connection (with a 1,000 Hz polling rate and the RGB lighting turned off). If you're using an 8,000 Hz polling rate, that number drops to 47 hours (with the lighting turned off) or 25.5 hours with the lighting turned on — which is better than we expected.
