Razer announced the Basilisk V4 Pro on October 8, a wireless ergonomic mouse with a 50,000 DPI optical sensor, 14 programmable controls and a battery rated for up to 200 hours at 1,000 Hz, in its launch release. Razer presents it as an ergonomic mouse built without compromise on control, precision or immersion. A second mouse, the Basilisk V4 HyperSpeed, and a Mouse Dock V2 Pro charging dock launch with it, and none of the three comes with a price or an on-sale date.
The sensor ceiling rises from 35,000 to 50,000 DPI, and wireless polling reaches 8,000 Hz
Razer says the Focus Pro 50K Gen-3 sensor is rated for 50,000 DPI, 930 IPS tracking speed and 90 G of acceleration. Its page for the Basilisk V3 Pro 35K lists 35,000 DPI, 750 IPS and 70 G for the older sensor. These are maximums rather than what a player runs day to day.
Polling is the more practical change. The release describes true 8,000 Hz polling in both wireless and wired modes, with a Frame Sync feature that aligns sensor scanning to the mouse. The V3 Pro 35K reached 8,000 Hz only through the Mouse Dock Pro or a HyperPolling dongle, both sold separately. For the V4 Pro, Razer points to the new dock, which has an integrated 8,000 Hz transceiver, so the wireless 8,000 Hz setup may still involve an extra purchase.
Battery life and click ratings go up while the lighting zones drop from 13 to 7
Razer says the V4 Pro is rated for up to 200 hours at 1,000 Hz on HyperSpeed wireless, and up to 275 hours over Bluetooth 6.2. The V3 Pro 35K page gave 140 and 210 hours.
The Gen-4 optical switches are rated for 100 million clicks with 12% lighter actuation, against 90 million for the V3's Gen-3 switches. Control count moves from 13 to 14 through a third side button and a new M1 edge button, and Razer says it moved the multi-function trigger for a more natural reach. Razer says the mouse is 12 g lighter than its predecessor, but the release gives no weight for the V4 Pro itself. Razer's 7-zone Chroma lighting replaces the 13 zones the V3 Pro 35K page lists.
A 94 g V4 HyperSpeed and a dock that several Razer devices can share complete the line
The Basilisk V4 HyperSpeed weighs 94 g, uses a Focus X 33K sensor, has 12 controls and runs up to 140 hours. The Mouse Dock V2 Pro charges the mouse magnetically, adds 8-zone Chroma underglow, and lets compatible Razer mice and keyboards share its transceiver. Compatible devices include the V3 Pro 35K and several BlackWidow keyboards.
No price or on-sale date was given. The 8,000 Hz and 200-hour ratings also come separately, so battery life at 8,000 Hz may only be known once a reviewer measures it.
