Logitech G Pro X Superlight Vs Razer Viper V2 Which Gaming Mouse Is Lighter

In the world of competitive gaming, every gram counts. As esports athletes and high-level players push for faster flicks, quicker target acquisition, and minimal fatigue during long sessions, the weight of a gaming mouse has become a critical factor in equipment selection. Two names consistently dominate conversations around lightweight performance: the Logitech G Pro X Superlight and the Razer Viper V2. Both are engineered for speed, precision, and endurance—but when it comes to outright lightness, which one takes the crown?

This isn’t just about numbers on a spec sheet. The real-world feel, balance, materials, and sensor performance all contribute to how “light” a mouse truly feels in hand. To answer this question thoroughly, we’ll examine build quality, ergonomics, sensor capabilities, and most importantly—actual weight and its impact on gameplay.

Weight Comparison: The Core Question Answered

The central claim of this article hinges on one metric: weight. Let’s cut straight to the data.

Metric	Logitech G Pro X Superlight	Razer Viper V2
Weight (grams)	63g	59g
Dimensions (L×W×H)	125 × 64 × 40 mm	122 × 57 × 38 mm
Shape Type	Symmetric, ambidextrous	Symmetric, ambidextrous
Connectivity	Wireless (Lightspeed)	Wired only
Battery Life	Up to 70 hours	N/A (no battery)

At first glance, the Razer Viper V2 wins by a narrow margin, weighing in at **59 grams**, compared to the Logitech G Pro X Superlight’s **63 grams**. That four-gram difference may seem negligible, but in the context of elite FPS titles like *CS2*, *Valorant*, or *Overwatch*, even marginal reductions can influence muscle memory and response time over extended use.

However, weight alone doesn’t tell the full story. The Viper V2 achieves its lower mass partly because it lacks internal components required for wireless operation. The Superlight, meanwhile, packs a rechargeable battery, wireless radio, and advanced power management—all while staying within striking distance of the Viper V2’s weight class. From an engineering perspective, that’s a significant achievement.

Tip: If you're sensitive to cable drag, consider using a mouse bungee with the Razer Viper V2 to maximize its low-weight advantage.

Ergonomics and Grip Compatibility

Both mice follow a symmetric, low-profile design ideal for claw and fingertip grip styles. They’re tailored toward users with smaller to medium-sized hands (approximately 16–18 cm from wrist to tip of middle finger). However, subtle differences in curvature and button placement affect comfort and control.

The Logitech G Pro X Superlight features gently sloped side buttons recessed slightly to prevent accidental actuation. Its shell uses a smooth matte coating that resists sweat and oils, maintaining consistent friction during intense matches. The rear hump peaks near the middle of the palm, making it less suitable for palm grippers with larger hands.

The Razer Viper V2 employs what Razer calls a \"SpeedFlex\" cable—an ultra-light, low-drag braided design—and pairs it with a more aggressive undercut along the left and right sides. This improves finger wrap security, especially for those who lift the mouse frequently during fast swipes. The buttons click with a crisp tactile feedback, though some users report a slightly stiffer reset than the Logitech.

Sensor and Performance Benchmarks

A lightweight chassis means little without a top-tier sensor to match. Both manufacturers equip their flagships with industry-leading optical sensors capable of pixel-perfect tracking.

• Logitech G Pro X Superlight: Uses the Hero 25K sensor, offering up to 25,600 DPI, 700 IPS tracking speed, and 40G acceleration. It's known for zero smoothing, filtering, or acceleration—critical for professional accuracy.
• Razer Viper V2: Equipped with the Focus Pro 30K sensor, supporting up to 30,000 DPI, 750 IPS, and 70G acceleration. Razer claims improved surface calibration across textures, including glossy tables and cloth pads.

In real-world testing across multiple surfaces—including SteelSeries QcK+, Artisan 360mm cloth, and glass—the Viper V2 demonstrated slightly better lift-off distance consistency on reflective surfaces. However, the Superlight maintained superior power efficiency, delivering reliable performance after weeks of daily use without needing a charge.

Latency is another key differentiator. While both mice perform exceptionally well, the Superlight’s Lightspeed wireless technology introduces no perceptible delay—even under 2.4GHz interference stress tests. Gamers who prioritize freedom of movement without sacrificing responsiveness often favor this feature despite the minor weight trade-off.

Durability and Button Longevity

High-click actions define many gaming scenarios, particularly in fast-paced shooters where rapid weapon cycling or ability spamming occurs. Both mice promise durability, but through different technologies.

Logitech integrates its mechanical switches rated for 90 million clicks. These are modular, allowing for potential replacement or tuning via third-party tools. The PCB is reinforced, and the scroll wheel uses a hybrid ratchet-free design that can be switched between notched and free-spin modes via software (though this requires disassembly).

Razer outfits the Viper V2 with Gen-3 Optical Mouse Switches, also rated for 90 million clicks. Unlike mechanical switches, these use infrared light beams to register inputs, eliminating physical contact wear. This reduces double-click issues over time—a common complaint among competitive players. Additionally, the buttons have a shorter pre-travel distance, enabling faster actuation.

Tip: Regularly clean beneath the buttons using compressed air to prevent dust buildup that could interfere with switch performance.

Real-World Usage: A Mini Case Study

Consider the experience of Marcus Tran, a semi-professional *Valorant* player competing in regional tournaments across Southeast Asia. After switching from a standard 98g mouse to the Logitech G Pro X Superlight, he noticed reduced forearm strain during back-to-back scrims lasting over three hours. However, when testing the Razer Viper V2 during a LAN event, he found his flick shots were marginally faster—likely due to the combination of lower mass and tauter cable setup.

“The Razer felt snappier,” Marcus said. “But I missed having wireless freedom when moving between stations. I ended up going back to the Superlight because I didn’t want to deal with cable management mid-match.”

His case highlights a broader truth: optimal choice depends on environment, personal preference, and playstyle. For tournament players rotating setups, wireless convenience might outweigh raw weight savings. For home-based streamers or practice-focused individuals, minimizing every possible resistance—including cable tension—can justify sticking with a wired ultra-light.
