Razer has officially uncovered the latest iteration in its esports lineup, the Viper V4 Pro. In addition, the Razer Gigantus V2 Pro was revealed, launching alongside the all-singing, all-dancing esports mouse.
The Viper V4 Pro emerges as one of the lightest, fastest, and most precise gaming mice on the market, providing the world’s greatest esports pro players with cutting-edge technology and the latest Razer-based innovations.
Viper V4 Pro is Unbelievably Fast on Paper
In a new press release, Razer sung the praises of the Viper V4 Pro, a white-hot esports mouse with some serious specs on paper.
The Viper V4 Pro delivers latency that can average as low as 0.204 ms for clicks and 0.36 ms for motion, leaning on 8,000 Hz polling in both wireless and wired modes. That’s blistering. The team also revealed that the Viper V4 Pro is registering 2.5 times faster in motion latency and has nearly double the battery life compared to ‘equivalent wireless gaming mice options.’
That double battery life comes in at a whopping 180 hours, by the way.
Razer has confirmed that the Viper V4 Pro boasts the next-generation Focus Pro 50K Optical Sensor Gen-3 under the hood, capable of up to 50,000 DPI, 930 IPS, and 90 G acceleration. It also comes with frame sync, a landmark technology that eliminates even more motion latency, allowing for the most responsive and accurate aim in the business.
The optical switches can withstand 100 million clicks, the scroll wheel is ‘3.3 times more reliable and consistent’, and it weighs as little as 49 grams but remains reinforced and robust.

Paired with the new Razer Gigantus V2 Pro, a five-tier mouse mat system that offers a range of friction and foam options, the Viper V4 Pro is undoubtedly set to be a fine addition to the esports peripherals space.
In a statement, the Global Esports Director at Razer, Jeffrey Chau, alluded to that fact:
In esports, matches swing on margins as thin as a few milliseconds. At that level, players can’t afford guesswork. They rely on what’s proven to win, which is why Razer has become the top choice of pro players.
The Viper V4 Pro is engineered to deliver faster, more consistent inputs where it matters most: live competition. Combined with the Gigantus V2 Pro’s speedspecific surfaces, this is a loadout built not just to keep up with the fastest plays in the game, but to outpace them.
The Razer Viper V4 Pro costs $159.99, and the Gigantus V2 Pro costs $49.99. Both are available now at Razer.com and stores worldwide.
