Not a significant upgrade over V3.Razer’s Viper linehas been one of the best options forcompetitive-level gaming micesince the V1 was introduced in 2019, packing top-of-the-line specs into an ambidextrous shape. The release of the Viper V4 allows Razer to remain competitive in the space, despite not breaking any tech barriers with major jumps in polling rates or DPI compared to the prior generation. With the V4, Razer focused on small, incremental improvements to squeeze more performance out of the same polling rate—a measure of responsiveness that gauges the frequency at which the mouse sends tracking data to your computer—by reducing latency and improving consistency.While the Viper V4 Pro is a fantastic mouse, V3 owners should not rush to upgrade. The improvements to performance and weight are small across generations, but impressive numbers nonetheless. Because of this, the V4 is a compelling option if you’re more than a generation behind and looking for an upgrade.If It Ain’t Broke …Viper V2 Pro (left), Viper V3 Pro (center), Viper V4 Pro (right)Photograph: Henri RobbinsViper V2 Pro (left), Viper V3 Pro (center), Viper V4 Pro (right)Photograph: Henri RobbinsComparing the exteriors of the Viper V3 and V4, you’ll struggle to see any differences. The two are essentially identical, save for a minor change to the specific shade of white. While it’s easy to dismiss Razer’s iterative design as lacking in innovation, the shape of the V3 was already fantastic, requiring little, if any, improvements.Like its predecessors, the V4 Pro is largely designed as an ambidextrous mouse. While some users might prefer a dedicated right-handed mouse for better ergonomics, the lightweight design will satisfy the needs of most gamers.The top curvature is comfortable on your palm, and both the length and width are meant for average-sized hands. Both sides of the mouse taper slightly for easier lifting, and the side buttons are placed optimally on the left side for a standard palm grip. The lack of side buttons on the right means this isn’t a “true” ambidextrous mouse, but there aren’t many of those on the market anymore. Because of this, lefties will have to do without side buttons for the time being. The only significant difference from other mice is the two main buttons, which feature Razer’s signature concave shape.Photograph: Henri RobbinsTo give the V4 lower latency and make the buttons last longer, Razer moved away from mechanical switches to optical sensors for the buttons and scroll wheel. Another benefit is that the tactile experience of each switch can be fine-tuned independent of the internal workings. With a standard mechanical switch, the two are inseparable from one another, which creates trade-offs between a switch’s feel and its functionality.The buttons have a short travel distance and an immediate, full-sounding click when pressed. The switches underneath require enough weight to prevent misclicks, but aren’t so heavy as to make inputs feel slow. The new optical scroll wheel has a significant, separated bump between each input, snapping into place immediately while still being easy to rotate. The side buttons feel slightly softer, with a more muted tone compared to the two main buttons.The real improvements to this generation’s Viper are under the hood. Razer reduced the weight by 5 grams (totaling 50 grams in white, or 49 grams in black). The mouse’s guts are capable of 8,000-Hz polling (the same as the V3) and 50,000 DPI (15,000 more than the V3), and the new hemispherical dongle (which I loved when reviewing the latest Deathadder) looks better on a desk and provides more information at a glance.While a 5-gram reduction in weight may sound minor, the improvements were immediately noticeable, leading to quick, snappy movements and flicks required in first-person shooters. In precision-focused games likeCounter-Strike 2, the weight felt perfectly balanced to throw around without being so light that I lost control, and in fast-paced titles likeHelldivers 2, the added agility gave me the ability to contend with multiple enemies at once (or, more accurately, easily turn around and flee from them).Instead of the singular RGB indicator of the V3’s hyperpolling dongle, the desktop bio-dome has three programmable RGB indicators to display one of four different settings: connection quality, battery level, poll
