PureVector is a personalized directional sensitivity calibration technology on the SABRE v3 PRO PureVector Series, in partnership with CORSAIR and Aimlabs. Rather than applying one sensitivity value to every direction of mouse movement, PureVector measures how a player aims in each direction and adjusts the mouse's directional sensitivity to match. Calibration happens inside the Aimlabs app, takes about five minutes, and is saved directly to the mouse's firmware.
This article walks through the full process: getting from CORSAIR Web Hub to Aimlabs, what each calibration question asks, how to read the results, and what to do once calibration is finished.
Once DPI and in-game sensitivity are set, they scale movement the same way in every direction the mouse moves. That carries an assumption: that a player's hand moves with the same speed and accuracy in every direction. In practice, moving a mouse away from the body, toward the body, and across the body are different movements, and most players are faster or more accurate in some directions than others. Aimlabs research found that this directional bias is individual, but it's consistent within a player. Because that pattern is stable, it can be measured and used to adjust sensitivity, rather than being left to trial and error or to copying another player's settings.
During a session of about five minutes, PureVector monitors as the player aims at targets across different directions, calculates metrics for each direction, and personalizes the relationship between hand movement and cursor movement so that weaker directions behave more like the player's strongest one. The calibrated settings are written to the mouse's onboard firmware. Nothing runs in the background while playing, and nothing adjusts input in real time.

PureVector requires current firmware on both the mouse and its wireless receiver. Both are updated with the CORSAIR Firmware Update Utility.
PureVector can be accessed in CORSAIR Web Hub, which also helps open Aimlabs, where the calibration takes place. To get started:
Installation for Aimlabs is through Steam.
Once Aimlabs is installed, sign in or create an Aimlabs account. An account is required to access PureVector's personalized calibration.
After signing in, navigate to Mouselabs in the top menu of Aimlabs. This opens the PureVector panel, where calibration is started.
Mouselabs has three tabs: My setup, PureVector, and Mouse settings. Before calibration, my setup shows a summary of the current sensitivity, cm per 360° turn, DPI, and mouse weight, along with the PureVector card and the Start calibrating button.
Clicking Start calibrating opens a short set of setup questions, followed by five rounds of SpiderShot. The questions are:
1) What’s going wrong?
This question asks which aiming problems sound familiar, such as overshooting a target, not turning fast enough, shaky small adjustments, or running out of mousepad. Multiple answers can be selected, and Not sure is available.
2) How do you hold it?
This question asks for grip style. Palm grip is the hand flat with full contact, Claw grip is arched with only the rear of the palm touching, and Fingertip grip is only the tips touching. Looking down at the hand and choosing the picture that matches works best. (you can read our article on different mouse grips for more detail.)
3) What moves when you flick?
This question asks which part of the arm drives a flick: the Wrist, Fingers, Arm, or Shoulder. A best guess is fine, since the warmup checks it either way. Choosing I don't know – work it out for me adds about 30 seconds to the warmup.
4) How big is your mousepad?
This question asks for mousepad size: Small (mouse only, tight), Medium (room for a full sweep), or Large (a desk mat with the keyboard on it). Mousepad size sets a physical limit on how much sensitivity can be used.
5) Your current setup
The final screen confirms the current setup. The mouse model is searched by name. In-game sensitivity is pre-filled from Aimlabs and can be edited in settings to match the value used in-game. The DPI should match the stage selected in Web Hub. I'm new to this game and I don't know my DPI are also available.
When the setup screen is filled in, click Start calibrating.
Complete Five Rounds
Calibration consists of five rounds of SpiderShot tasks. Each round lasts one minute and begins when the player clicks, so the full process takes about five minutes. After each round, a results screen shows the player's aiming bias against perfect aim, along with any tendencies detected. A counter tracks progress, for example "1/5 Completed," and Next task starts the following round.
After the fifth round, the screen reads "Calibration complete." Clicking Done saves the calibration data to the mouse’s firmware.
Back in Mouselabs, the panel now shows additional data. The PureVector card on the left confirms that directional sensitivity has been calibrated and applied to the mouse. It also holds three controls: Refine calibration, an information button, and a reset button.
Selecting the PureVector tab on the right shows Before PureVector and After PureVector graphs. Each plots aiming performance across eight directions, with the player's aiming bias drawn against a reference for perfect aim, and lists the share of perfect flicks, underflicks, and overflicks.
The After graph does not fill in right away. It requires at least five more rounds of any Aimlabs task after the first calibration. Until then, it reads "Continue playing to calculate." Once enough rounds are recorded, the two graphs can be compared side by side.
All five calibration rounds are recorded. Watch my replays opens the play history, and any round can be selected to watch its replay. Play history lists only the 50 most recent plays, so calibration replays are easiest to find soon after calibrating.
The calibrated settings are written to the mouse's onboard firmware, so Aimlabs can be closed once calibration is saved. No background app runs while playing, and the settings work in any game, including on a LAN PC with nothing installed.
As muscle memory develops through training, directional bias can shift. Refine calibration in the PureVector card runs the process again, and a new session takes about five minutes. Changes to grip, mousepad, DPI, or in-game sensitivity are also reasonable prompts to recalibrate, since the setup questions describe each of these.
Remove calibration in the PureVector card deletes the calibration data from the mouse. This is also required before calibrating a different DPI stage.
PureVector calibrates one DPI stage at a time. To calibrate a different DPI stage, first remove the current calibration with the Remove calibration button in the PureVector card, then select the new DPI stage in Web Hub and run calibration again
