Lighter, Faster, More Precise - The New King of Esports Mice
The Razer Viper V3 Pro is currently the most-used mouse in professional esports. Tournament-winning pros across every major game trust it. So when Razer announced the V4 Pro, they had one job: make the best even better without breaking what works.
Mission accomplished.
The Viper V4 Pro is approximately 49g (50g in white) - 9% lighter than the V3 Pro. It features next-gen HyperSpeed Wireless with 0.204ms average click latency and 0.36ms motion latency. It packs a Focus Pro 50K sensor with revolutionary Frame Sync technology that aligns sensor frames with polling cycles for just-in-time scanning. And it pairs perfectly with the new Gigantus V2 Pro mousepad, available in five distinct speed ratings so you can dial in your exact preference.
This is the setup pros use. Now it's available to everyone.
Refined by Legends
Razer didn't just throw specs at a wall and hope something stuck. They worked directly with esports legends like Lee "Faker" Sang-Hyeok (six-time League of Legends World Champion) and Nikola "NiKo" Kovač (10-time Counter-Strike Championship MVP) to refine every detail.
"The Viper V4 Pro feels like an extension of my hand. Its responsiveness is exactly what is needed for high-stakes matches," said Faker. When the GOAT of League says your mouse is responsive enough, you know you've built something special.
Jeffrey Chau, Global Esports Director at Razer, explained the philosophy: "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. The Viper V4 Pro is engineered to deliver faster, more consistent inputs where it matters most: live competition."
HyperSpeed Wireless Gen-2 with True 8000Hz Polling
The V4 Pro debuts Razer's next-gen wireless platform (first seen in the DeathAdder V4 Pro) and pushes it even further. We're talking:
That motion latency improvement isn't just a spec sheet flex. It's the difference between your crosshair being where you think it is versus where it actually is. At 0.36ms, the lag is basically imperceptible.
Focus Pro 50K Optical Sensor Gen-3: Frame Sync Changes Everything
The sensor is where things get really interesting. Up to 50,000 DPI, 930 IPS tracking, and 90G acceleration are all impressive. But the real innovation is Frame Sync.
Frame Sync is the first sensor technology that aligns sensor frames with the mouse's scanning and polling cycle. Translation: the sensor only scans exactly when it needs to report data, eliminating wasted sensor updates and reducing motion latency even further while improving battery efficiency.
It's just-in-time scanning that makes your aim faster and more responsive while using less power. That's actual innovation, not marketing BS.
The sensor also includes pro-level software tools:
Optical Everything: Built to Last
Razer went full optical on the V4 Pro, and for good reason:
Optical Mouse Switches Gen-4 - Completely redesigned architecture with up to 100-million-click lifespan. Zero debounce delay means your clicks register instantly, with no double-click issues. You get true mechanical tactile feedback but with optical actuation's consistency and speed.
Optical Scroll Wheel - Tuned specifically for esports, this scroll wheel is 3.3x more reliable than mechanical designs. No more accidental weapon swaps mid-fight, no missed ability scrolls, no inventory navigation fails. When you scroll, it scrolls - exactly once, exactly when you want.
Ultra-Light, Ultra-Balanced Design
At approximately 49g (black) / 50g (white), the V4 Pro is about 9% lighter than the already-light V3 Pro. But here's the impressive part: it's achieved through mechanical optimization, not hollowing out the shell.
Refined shell thickness, more compact PCB, and reinforced structural elements mean it feels exceptionally light but still reassuringly solid. No creaks, no flex, no cheap feeling. Just performance.
Engineered for claw and fingertip grips, the shape is proven in competition. Don't fix what ain't broke.
Plug-and-Play Performance
The optimized hemispherical dongle has integrated LED indicators for at-a-glance status. Razer Synapse Web means browser-based tuning without installing software. Quick onboard adjustments let you change DPI and polling rate on the fly for instant in-match optimization.
No software bloat. No configuration hell. Just plug in and frag.
Choose Your Speed, Own Your Playstyle
The Gigantus V2 Pro isn't just "a mousepad" - it's five specialized mousepads designed for five different playstyles. Each speed rating has matching foam firmness tuned specifically for that glide profile.
Developed and tested with pros like NiKo, Faker, and Zellsis, each surface reflects different competitive demands.
The Five Speed Ratings:
Max Control - Ultra-high friction for flick precision. Cushioned GlideCore foam gives you precise stopping power. Perfect for AWPers, snipers, and players who need pixel-perfect flicks.
Control - High friction for consistent micro-adjustments. Ideal for tracking-heavy roles and players who value precision over speed.
Balance - Medium friction hybrid glide. The Goldilocks zone for players who want the best of both worlds.
Speed - Low friction for fast swipes. Firmer foam for quicker response. Great for entry fraggers and aggressive players.
Max Speed - Ultra-low friction for lightning-quick movements. Firmest foam, fastest glide. For players with low sens who need to cover massive distances quickly.
NiKo put it simply: "It's the most complete mouse mat I've used. That's why I chose it for my collection."
Razer Proprietary GlideCore™ Foam
Each speed rating is paired with specific GlideCore foam that delivers tailored feel and stopping power. From cushioned precision on Max Control to firm, fast response on Max Speed, the foam matches the surface.
Optimized for Optical Sensors
Lab-tested with leading optical sensors to ensure pixel-perfect tracking across the entire mat. Every flick, micro-correction, and wide swing feels consistent - no dead zones, no tracking issues, no surprises.
Built for Competition
What You're Getting:
Viper V4 Pro:
Gigantus V2 Pro:
Let's be clear - this is pro-grade gear. The Viper V4 Pro is for competitive gamers who need every advantage they can get. Players who understand that 0.2ms of latency actually matters. People who care about sensor technology, switch consistency, and weight distribution.
