Corsair Glaive Firmware Update Fails at 0%

Sensor

PixArt PMW3391—a sensor that’southward rather unique and just available in Corsair mice as of now. It’s based on the PMW3389, so it has very similar specifications, though in that location are some improvements. This tracking unit is just fantastic, absolutely raw and responsive at fifty-fifty its maximum tracking speed, without any added acceleration, bending snapping, or any sort of filtering. There’due south some smoothing on and higher up 2100 CPI, which is commonly the case with most newer PixArt sensors, and information technology’southward there to reduce jitter on the higher resolution steps.

Now for some specifications—the nominal maximum tracking speed and dispatch values are ridiculously high at 400 IPS and 50 Yard; there is no mode of hitting these values during regular use. Resolution tin can be ready from 100–18,000 CPI in steps of 1 CPI (which is still unique to this sensor). The available polling rates are 1000, 500, 250 and 125 Hz, which respectively translates to nominal response times of one, 2, iv and 8 ms. Lift-off distance tin can be configured in the software’s surface calibration option, which I highly recommend doing considering the default LOD is unusually high.

Paint Test

There is no jitter on the reasonable CPI steps, and I couldn’t find whatsoever unwanted angle snapping or sensor rattle either.

CPI Divergence

CPI difference is essentially the aforementioned equally on all PMW3391-equipped mice, which ways the measured values are 5–vii% higher than the nominal ones. Based on my testing, this is just a tad higher than boilerplate, so in that location’s nothing to worry about—if yous come from a mouse with a perfect CPI accurateness, yous should consider lowering your in-game sensitivity, though.

Perfect Command Speed

Perfect control speed (or PCS for short) is extremely high on this sensor as 400 IPS is over 10.six m/s. There is absolutely no way of hitting it while using the mouse normally—hitting 400 IPS volition however be very challenging on fifty-fifty a 2 m long mouse pad.

This exam shows the sensor’due south accuracy at unlike speeds. You lot can come across me doing a fast swipe to the right before I slowly slide the mouse back to its original position. At that place is pretty much no dispatch or deceleration here.

Polling Rate & Stability

We are at a point where I tin again (for a third time so far) objectively complain about RGB lighting. While I wasn’t exactly sure about this on the Ironclaw Wireless, this mouse certainly shows how LEDs can affect operation. With any of the three RGB lighting zones active, the mouse periodically drops its polling rates, which produces serious anomalies on measurements. This means the Glaive RGB Pro is unstable with any lighting, which is simply outrageous and shouldn’t exist overlooked if y’all inquire me.

One time I disabled all customizable LEDs, the polling rate instantly stabilized, and the mouse performed perfectly without any errors. If you remember the Libation Master MM830 review, this issue was nowadays in that location as well, and they could solve information technology with a firmware update—I hope Corsair will follow their instance, and I take notified them about the matter.

With disabled RGBs, all available polling rates are nice and stable, without any periodic drops or suspicious outliers.

Input Lag & Smoothing

There is no measurable smoothing or any other delay below 2,100 CPI. Some smoothing kicks in at or above ii,100 CPI, resulting in about +2–3 ms of input lag. Information technology reaches virtually +ten ms on 18,000 CPI, which is the highest bachelor resolution. For competitive gaming, I would highly advise staying beneath 2,100 CPI for no smoothing. For annihilation else, experience free to use whatever you like that’due south within reasonable bounds. I personally accept no clue why peripherals-producing companies still fight this CPI state of war. In my opinion, annihilation above 6,000 is ridiculous on even a 4K brandish, only hey, information technology is again a matter of personal preference.

Click Latency

Click latency is roughly +4.4 ms when compared to the SteelSeries Ikari, which is considered as the baseline with 0 ms. The data comes from

and my ain testings (please annotation that this review’s nautical chart simply contains right-handed ergonomic mice for comparison). Testing was done with a Logitech G102 and the Glaive, using
