They fixed it! But at what cost? - Corsair Sabre V2 Pro

Quick Overview

The Corsair Sabre V2 Pro, while lightweight and featuring a high-end Marksman S sensor and 8000Hz polling rate, suffers from a significant input latency issue (9ms wireless, 8.2ms wired) caused by double-clicking/debouncing, which the reviewer considers a major flaw that outweighs its excellent specs and low weight for competitive gaming.

Key Points: The Corsair Sabre V2 Pro weighs an extremely light 36g (0.08 lb) without using a honeycomb design. The mouse features the high-performance Corsair Marksman S sensor, supporting up to 33,000 DPI, 750 IPS tracking speed, and 50G acceleration. It supports an 8000Hz polling rate, offering 16 hours of battery life at that setting, or 70 hours at the standard 1000Hz. Wired click latency measured 8.2 ms, while wireless (8000Hz) measured 8.4 ms, which the reviewer deems too high compared to the 1ms gold standard. The primary issue stems from double-clicking/smash-clicking debouncing, which adds noticeable input latency (9ms wireless, 8.2ms wired). The mouse includes accessories like extra grip tape (3M adhesive), an alcohol pad, and PTFE glides. The reviewer suggests this latency issue is a major drawback, especially given the $99.99 price point, making it less recommendable than cheaper competitors like the Dareu A950 Wing.

Context: This video is a review of the Corsair Sabre V2 Pro Ultralight Wireless gaming mouse, focusing heavily on its performance metrics, especially latency, compared to industry standards and competitors. The reviewer unboxes the product, discusses its physical features and included accessories, and then dives into objective testing results from TechPowerUp regarding click latency before testing its responsiveness in the game Apex Legends.

Detailed Analysis

The Corsair Sabre V2 Pro is an ultralight wireless gaming mouse weighing only 36g, achieved without a honeycomb shell. It utilizes the Corsair Marksman S sensor, capable of 33,000 DPI, 750 IPS, and 50G acceleration. The mouse supports an 8000Hz polling rate, yielding 16 hours of battery life at that setting or 70 hours at 1000Hz. Upon testing click latency, the wired mode measured 8.2 ms, and wireless at 8000Hz measured 8.4 ms, both significantly above the sub-1ms standard for top-tier gaming mice. The reviewer attributes this latency issue to the mouse's debouncing settings designed to prevent double-clicking, which adds 8-9ms of delay. While the mouse feels great physically—lightweight and featuring good main button clicks—the reviewer finds the fixed, high latency a significant drawback, especially considering its $99.99 price, suggesting competitors like the Dareu A950 Wing offer similar specs for less money without this latency penalty. The reviewer notes that while Corsair offers firmware updates, the latency issue appears inherent to the current switch tuning.
