Razer Basilisk V4 Pro Debuts With 50K Sensor, 14 Controls and 8,000 Hz Polling

Razer has given its Basilisk gaming mouse a serious update, and the most useful change may not be the headline sensor number. The newly announced Basilisk V4 Pro combines more programmable inputs with a scroll wheel that can switch between precise steps and fast free-spinning movement. It is aimed at players who want one mouse for games, work and everything between them.

Announced on October 8, 2026, the V4 Pro adds a Focus Pro 50K Optical Sensor Gen-3, 14 customizable controls and support for up to 8,000 Hz polling over both wired and wireless connections. Razer also introduced a less expensive Basilisk V4 HyperSpeed and the optional Mouse Dock V2 Pro. Those are separate products, not accessories automatically included with the standard Pro mouse.

A scroll wheel built for more than scrolling

Razer's HyperScroll Tilt Wheel Gen-2 is the part worth examining if you switch between shooters, strategy games and spreadsheets. Its standard tactile mode uses 24 steps. A new Precision Tactile mode offers 48 finer steps, which could make cycling through a long list of items or in-game abilities easier to control. Free-Spin mode lets the wheel move rapidly through long pages, while Smart-Reel can switch modes automatically based on how quickly you scroll.

There is also Virtual Acceleration in Razer Synapse, with five adjustment levels. These are configuration options rather than guarantees that a player will aim better. Someone who likes a simple fixed scroll wheel may not need them. For a person who routinely switches between a game inventory, editing software and a browser, the flexibility is more compelling.

Razer has moved the Basilisk's multi-function trigger to what it describes as a more natural position, added a third side button and introduced an M1 edge button. Together, the mouse offers 14 customizable controls. Hypershift lets a control activate a secondary function, while Synapse profiles can change mappings for specific games.

The 50K sensor and 8,000 Hz claim need context

The Focus Pro 50K Optical Sensor Gen-3 is rated for up to 50,000 DPI, 930 inches per second and 90 G acceleration. The V4 Pro supports true 8,000 Hz polling through HyperSpeed Wireless Gen-2 as well as wired operation. In principle, more frequent reports can reduce the interval between mouse updates, but actual responsiveness depends on the PC, game, connection and settings.

An 8,000 Hz option is not a reason to expect an eightfold improvement in performance over a 1,000 Hz mouse. The higher setting can also create more USB and CPU activity and generally changes the battery trade-off. Razer's published battery estimate of up to 200 hours on HyperSpeed Wireless Gen-2 specifically uses 1,000 Hz. Its up-to-275-hour figure is for Bluetooth 6.2. Neither should be presented as an 8,000 Hz battery-life promise.

Razer also lists fourth-generation optical switches rated for 100 million clicks. That is a manufacturer durability rating, not a real-world lifespan guarantee. Seven-zone Chroma RGB lighting with full underglow adds visual customization, although lighting can affect battery life depending on use.

A cheaper Basilisk and a separate charging dock

The Basilisk V4 HyperSpeed is the more restrained alternative. Razer lists a Focus X 33K Optical Sensor Gen-3, 12 customizable controls, a 94 g weight and up to 140 hours on its HyperSpeed wireless connection. The simpler model may suit someone who wants the familiar ergonomic shape without paying for the Pro's full feature set.

The Mouse Dock V2 Pro is a separate magnetic charging accessory with an integrated 8,000 Hz transceiver and RGB underglow. Razer says it can also connect compatible Razer mice and keyboards. Do not assume it will work with every older Razer mouse; compatibility needs to be checked model by model. The dock shown in promotional images is not automatically part of a standard Basilisk V4 Pro purchase.

US prices and the Philippine peso equivalent

Razer's US store lists the Basilisk V4 Pro at approximately ₱10,669.59 (US$169.99) and the Basilisk V4 HyperSpeed at approximately ₱6,903.63 (US$109.99). It also lists a V4 Pro plus Mouse Dock V2 Pro bundle at approximately ₱13,180.23 (US$209.99). These peso figures are currency conversions, not official Philippine suggested retail prices or confirmed prices at local retailers.

The conversions use the Bangko Sentral ng Pilipinas' October 8, 2026 reference rate of ₱62.7660 per US dollar. Philippine shelf prices may differ because of tax treatment, import costs, retailer margins and promotions. At publication time, we have not verified a Philippine MSRP for the new V4 models.

Should you upgrade?

The strongest case for the V4 Pro is its combination of ergonomic shape, extra controls and flexible scroll wheel. A player who uses macros across several games or frequently works in applications with long timelines and lists could get value from those changes. The flagship is less persuasive if you already own a reliable mouse, use only a few buttons and never change polling or wheel modes.

For Philippine buyers, wait for an actual local listing before treating the converted US price as a shopping budget. Check whether the dock is bundled, confirm warranty coverage and compare the less expensive HyperSpeed model with the Pro. Razer has published the specifications and US prices, but independent testing is still needed to judge comfort, click feel, battery life under demanding settings and whether the new scroll modes are worth the premium.
