Expert Features

• 49g Esports Weight : The black Viper V4 Pro weighs just 49g, keeping rapid flicks, resets, and micro-adjustments brutally fast without sacrificing the familiar Viper competitive shape.
• Razer HyperSpeed Wireless Gen-2 : Razer’s latest wireless platform supports true 8000Hz polling, with Razer claiming over 60% greater efficiency and 55% lower latency versus its previous generation under standard test conditions.
• 8000Hz Wireless + Wired Polling : Run the mouse at up to 8000Hz / 0.125ms polling whether you play wirelessly or through the USB cable—no need to surrender maximum polling just because you unplug.
• Focus Pro 50K Sensor Gen-3 : The new optical sensor reaches 50,000 DPI, 930 IPS, and 90G acceleration, with Frame Sync technology designed for ultra-consistent high-speed tracking.
• Ultra-Low Motion Response : Razer specifies motion latency as low as 0.36ms, targeting the split-second tracking demands of serious competitive play.
• Gen-4 Optical Main Switches : Razer Optical Mouse Switches Gen-4 are rated for 100 million clicks, eliminate traditional debounce delay, and are designed to avoid mechanical double-click issues.
• Razer Optical Scroll Wheel : A 24-step optical scroll wheel replaces a traditional mechanical encoder for improved precision, tactile control, and durability during high-intensity weapon swaps and movement inputs.
• Up to 180-Hour Battery Life : Get up to 180 hours at 1000Hz or up to 45 hours at 8000Hz, letting you choose marathon endurance or maximum competitive polling performance.
• 6 Programmable Controls : Configure six programmable controls for essential commands, shortcuts, or macros through Razer Synapse.
• Advanced Sensor Tuning : Synapse supports Dynamic Sensitivity, Rotation Tool, 1-DPI step adjustments, Sensitivity Matcher, Asymmetric Cut-Off, and Smart Tracking for players who actually tune their aim instead of blaming the mouse.
• Smart Polling Rate Switcher : Assign polling rates to specific games and let Razer Synapse automatically switch polling behavior according to the title being played.
• 100% PTFE Feet : Large 100% PTFE mouse feet help the 49g chassis glide smoothly across compatible mouse surfaces.
• USB-C Wired Connectivity : Play wired or charge through the mouse’s USB Type-C port, using the included USB Type-A to USB Type-C cable.
• No RGB, No Dead Weight : The Viper V4 Pro deliberately skips RGB lighting, keeping its esports design focused on weight, speed, tracking, and competitive efficiency.
