Corsair RGB Gaming Mouse Round-Up: M55, Glaive Pro, Nightsword, Ironclaw Tested

Let's take a moment to go over the sensors. The Corsair M55 is the odd-man-out with its PAW3327 sensor. It is capable of a "mere" 12,400 DPI resolution with tracking up to 220 IPS and 30 G of acceleration. Realistically, this sensitivity puts it an order of magnitude greater than anyone will likely use, so its resolution is a non-issue.


The tracking metrics on the other hand conceivably could be an issue for some. Quick and sudden movements, such as snapping for a headshot, could result in less-precise targeting and missed kills. 220 inches per second translates to 12.5 miles per hour (5.6 meters per second) which is fast, but not outside the realm of possibility.


If your gameplay style does entail a lot of fast action, the Pixart PWM3391 sensor found in the other three mice should have you covered. Only the Flash runs any danger of outstripping its 18,000 DPI sensitivity with 400 inches per second of tracking at 50 G. It almost seems silly to have such a precise sensor in a mouse, but we are not ones to shy away from overkill.


Speaking of overkill, the PWM 3391's sensitivity is adjustable in single DPI increments. The M55, for comparison, is only adjustable in 100 DPI increments. Whether this added control makes a significant difference or not is hard to say. We find 100 DPI jumps fairly easy to adapt to, but pickier users may disagree and we would love to hear your thoughts.


We tested all the mice on a variety of surfaces - hard and soft mousepads, a bare desk, clear hard plastic, skin, and loose fabric. We did not encounter any trouble getting the mice to register. The PWM3391 equipped mice do offer a surface tuning calibration which may help squeeze an extra ounce of performance out of the tracking. In all honesty, we do not notice a difference before and after calibrating, but do find that post calibration the mice can stop or worsen tracking on other surface types.
