Razer has just announced the Viper V4 Pro wireless gaming mouse alongside the Gigantus V2 Pro mouse mat lineup, both designed with direct input from professional esports players to deliver faster response times and tailored control for competitive gaming.
The Viper V4 Pro builds on the success of its predecessor, the V3 Pro, which remains the most popular mouse among esports professionals and it still is my best and most favourite gaming mouse ever. I really like the shape of the mouse and I got so many consistent performance with this mouse. Make sure to check my Viper V3 Pro while you’re here.
This latest iteration pushes performance further with improvements to weight, latency, and tracking precision, while the Gigantus V2 Pro introduces five distinct speed ratings so players can match their mouse mat surface to their specific playstyle.
Razer Viper V4 Pro
Razer worked directly with top-tier players including League of Legends champion Lee “Faker” Sang-Hyeok and Counter-Strike MVP Nikola “NiKo” Kovač during development. The focus was on measurable performance gains rather than superficial features, addressing the millisecond-level margins that separate wins from losses in competitive play.
So you probably won’t find any new, groundbreaking technology with the mouse, but almost everything within the mouse has been upgraded.
The Viper V4 Pro comes in at approximately 49 grams for the Black edition and 50 grams for White, making it around 9% lighter than the V3 Pro. This weight reduction was achieved through mechanical optimisations including refined shell thickness and a more compact PCB, while maintaining structural integrity.
At the core is Razer’s HyperSpeed Wireless Gen-2 technology with true 8,000 Hz polling in both wireless and wired modes. Latency averages have dropped to 0.204 ms for clicks and 0.36 ms for motion, representing approximately 2.5 times faster motion latency compared to the previous generation. Battery life extends up to 180 hours at 1,000 Hz polling, nearly double the runtime of comparable wireless gaming mice.
The Razer Focus Pro 50K Optical Sensor Gen-3 supports up to 50,000 DPI, 930 IPS, and 90 G acceleration. A new Frame Sync technology aligns sensor frames with the mouse’s scanning and polling cycle, minimising motion latency while improving battery efficiency by eliminating redundant sensor updates. This is pretty big, actually.
Additional features include Dynamic Sensitivity, Mouse Rotation, 1 DPI step adjustments, Sensitivity Matcher, Asymmetric Cut Off with 26 levels, and Smart Tracking capabilities.
The optical scroll wheel offers 3.3 times more reliability than traditional mechanical designs, preventing unintended inputs during weapon swaps or ability cycling. Razer’s fourth-generation Optical Mouse Switches deliver a 100-million-click lifecycle with zero debounce delay, maintaining true mechanical tactile feedback while eliminating double-click issues.
Razer Gigantus V2 Pro Mouse Mat Options
The Gigantus V2 Pro range introduces five speed ratings, each with matching foam firmness through Razer’s proprietary GlideCore foam technology. Players can choose between Max Control (ultra-high friction for flick precision), Control (high friction for micro-adjustments), Balance (medium friction for hybrid glide), Speed (low friction for fast swipes), and Max Speed (ultra-low friction for lightning-quick movements).
Each surface was developed and tested with professional players including NiKo, Faker, and Zellsis to reflect the different demands across competitive roles from riflers to duelists to ADCs.
The mouse mats feature low-profile stitched edges to resist fraying, an anti-slip base for stability during intense matches, and a rollable, warp-resistant design for easy transport to competitive events. All variants have been lab-tested with leading optical sensors to ensure consistent tracking across the entire surface.
Razer Viper V4 Pro First Impressions with Gigantus V2 Pro
Five grams lighter (compared to the V3 Pro White Edition) may not mean much but it still is somewhat noticeable, especially if you are a low DPI player who likes to lift the mouse up and down frequently on the mouse mat. I like how Razer does not make a change in terms of the mouse design, because I like the Viper best for my hands. I’ve recently reviewed the DeathAdder V4 Pro and I still like the Viper better as it is smaller with taller shape.
Everything inside has been upgraded too: its sensor, its wireless connectivity, and more. So you’ll feel right at home if you are used to using the VIper V3 mouse but with the latest tech and goodies that Razer has achieved for the past months. This means you’ll get more consistent headshots, less latency, better battery life, etc. I’ve honestly already got great performance out of the Viper V3 Pro and need more testing with the V4 Pro, but the Viper V4 Pro gives a consistent performance and stability.
I was sent the Gigantus V2 Pro Control and Balance mouse mats. Those who prefer a higher friction should definitely go for the Control but if you don’t know what to pick, Balance is definitely a great middle ground. It still has that smooth feel while having some friction as you track opponents with the mouse.
The Viper V4 Pro glides smoothly on the mouse mat and its large size definitely means you’ll need more space on the desk. But if you do, you’ll get more area to swipe your mouse on while improving the consistency of your aim.
Australian Pricing and Availability
The Razer Viper V4 Pro is available now for AU$279.95 at Razer.com, RazerStores, and select retailers worldwide. The Razer Gigantus V2 Pro in Large size (500 x 480 x 4 mm) retails for AU$89.95, with the Max Speed variant arriving at a later date.
