PureVector: The Future of Aiming

Mouse sensitivity takes time to dial in, and most players only ever get near their true sensitivity. DPI and in-game sensitivity are the two numbers players focus on, and once they are set, they scale movement the same way in every direction the mouse moves. This is where mouse sensitivity breaks down. Everyone aims differently, because biomechanical movement varies from person to person, so a default sensitivity isn’t suitable for every player. In some directions, the hand moves faster or more accurately than in others, which causes the cursor to overshoot a target and correct back onto it, and that correction adds time to a player's aim. Players have spent years tweaking these values and copying professional settings, often without a reliable way to know whether the result suits their own hand.

PureVector, a CORSAIR and Aimlabs collaboration, debuts on the SABRE v3 PRO PureVector Series. It is built on a patented algorithm and more than 4 billion datasets on how players aim, collected through Aimlabs, the number one aim training platform with more than 50 million downloads. The goal is to replace that uniform scaling with a sensitivity built from how an individual player actually aims, so the cursor reaches the target with less overshoot and correction, helping players aim faster. Once calibrated, the settings are saved to the mouse itself and carry into any game without background software, delivering up to 81ms of Aim Speed improvement, a 33% improvement in the aim phase.

This article will cover how a shot breaks into phases, the problem PureVector addresses, the technology behind it, how the calibration works, and how that result was measured.

A shot in a first-person shooter is not a single action. It breaks into three phases, and the time spent in each one adds up to the total time to shot.

1. Detect and Decide is the first phase. The player sees a target, recognizes it, and chooses a response. This phase happens before the mouse moves, and it depends mostly on the player's perception and reaction rather than on hardware.
2. Aim is the second phase, made up of movement and correction. The player moves the mouse to bring the cursor onto the target and, if the cursor overshoots or falls short, corrects. This phase depends on the player's hand, the mouse, and how the sensitivity setting translates from one into the other. It is also the phase where PureVector's beta test results were measured, including the up to 81ms Aim Speed improvement and 33% improvement in the aim phase.
3. Click is the third phase. The click registers, along with any input latency. This phase depends on the mouse's switches and how quickly it responds.

Each phase contributes a different amount of time to the shot, as the chart below shows.

Much of the recent conversation about mouse performance has centered on the click phase, and faster switches and quicker click response are real improvements for players who want every phase of a shot to be as short as possible. Click is also the smallest slice of a shot, while aim is the largest, and it is where overshoot and correction add time. Movement and correction take the most time of the three phases, which makes aim the most important portion of a shot to improve. CORSAIR and Aimlabs built PureVector to give players a better way to improve their aim in that phase. A given percentage improvement saves more time in a longer phase than in a shorter one, which is why the aim phase is where PureVector focuses.

One common source of lost time inside the aim phase is sensitivity that is uniform in every direction. DPI and sensitivity settings carry an assumption: that a player's hand moves with the same speed and accuracy in every direction. Biomechanically, that does not hold. 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.

This shows up in aim traces. In directions where a player's movement matches the sensitivity well, the cursor travels almost straight to the target. In other directions, the cursor overshoots, passes the target, and corrects back onto it. That correction adds time to the aim phase, repeated on every shot.

Aimlabs research identified two more properties of this directional bias:

• It is individual. Every player's bias has a different shape. Copying a professional's settings carries no guarantee of improvement, because those settings were tuned to someone else's hand.
• It is consistent within a player. An individual's pattern holds across tasks and across games. A stable signature can be measured reliably, and anything that can be measured reliably can be corrected.

That second finding is what makes PureVector possible. Because a player's directional pattern is stable, it can be measured once and used to adjust sensitivity, rather than being left to trial and error. Pairing that stable signature with Aimlabs data on how players move is what allows sensitivity to be calibrated to the individual, as the next section explains.

The name comes from mathematics: a vector is a direction plus a magnitude. PureVector measures both, meaning which direction a player aims and how far and how accurately the hand moves, then adjusts sensitivity to match. PureVector is built on a patented algorithm and more than 4 billion datasets, developed through the CORSAIR and Aimlabs collaboration.

1) Measure. Calibration runs inside the Aimlabs app with a SABRE v3 PRO PureVector mouse connected. During a session of about five minutes, PureVector monitors individual performance as the player aims at targets across different directions.

2) Calculate. From that session, PureVector calculates performance metrics for each direction, including distance moved and relative accuracy. The result is a personal directional profile showing where a player's aim runs long and where it lands accurately.

3) Adjust. PureVector personalizes the relationship between hand movement and cursor movement. The hand itself does not change. The mouse changes how it translates movement, so that weaker directions behave more like the player's strongest one.

4) Save. The calibrated settings are written to the mouse's onboard firmware. Aimlabs can then be closed. No background app runs while playing, and the settings work in any game, including on a LAN PC with nothing installed.

PureVector calibrates one DPI stage at a time, and the other DPI stages are disabled after calibration. To use PureVector at a different DPI, the current calibration must be removed first. Calibration can be repeated at any time: as muscle memory develops through training, directional bias can shift, and a new session takes about five minutes.

Once saved, PureVector is a sensitivity setting stored on the mouse, broken down by direction. It does not aim for the player, nothing runs in the background, and nothing adjusts input in real time during play. The calibration measures where a player's aim already tends to land, and it does not change where the player chooses to aim.

• Targets the longest phase of a shot. Fewer overshoots and corrections means less time spent in the aim phase, which takes the largest share of a shot.
• Personalized directional sensitivity. Settings come from measured movement rather than guesswork or another player's configuration.
• Set up once, used anywhere. Because the calibration lives in firmware, it carries into every game without additional software.
• Adapts over time. Recalibrating as aim develops keeps the profile matched to the player's current movement.

In practice, what changes is how the cursor settles onto a target. With sensitivity matched to the way a player moves in each direction, movements that used to overshoot should need less correction, which shortens the aim phase. In beta testing, that showed up as up to 81ms of Aim Speed improvement and higher scores in every skill group. PureVector does not affect the detect and decide or click phases, and the size of the gain varies from player to player, with novice players seeing the largest score improvement in beta testing. What players can expect is a sensitivity that fits their own movement, and recalibrating as their aim develops keeps it that way.

As described earlier, every shot breaks into three phases: detect and decide, aim, and click. The data below shows how PureVector improves the aim phase and how that translated into scores during beta testing.

Effect on the Aim Phase

In beta testing in Aimlabs across skill levels, PureVector improved Aim Speed by up to 81ms, a 33% improvement in the aim phase. The 33% figure describes the aim phase only, not total time to shot, and individual results may vary.

The comparison above applies that gain to an illustrative shot of about 525 ms. The aim phase shortens, and the total time to shot falls to about 444 ms. Because 81ms is one third of the aim phase but a smaller share of the whole shot, about 15% of the total in this example, the gain is specific to the aim phase. The detect and decide and click phases are unchanged, since PureVector acts on movement and correction.

Beta Testing Results

Across the PureVector beta, score improvement was measured on the same task in Aimlabs SpiderShot Pro, grouped by skill level:

*Score improvements in Aimlabs SpiderShot Pro during PureVector beta testing. Individual results may vary.

Every group improved. The pattern follows the room available for improvement: novice players gained the most, and pro players, who have the least room, still gained 8% on average. Using one task for every group keeps the comparison consistent, so the difference between groups reflects the players and not the test.

How to Read the Numbers

The two sets of results measure different things, and they are not meant to be added together or compared directly. Aim Speed describes time, in milliseconds, spent in one phase of a shot. Score improvement describes a percentage change in an Aimlabs task score.

Both results are reported as improvements and as ranges or averages, so individual results will vary. The Aim Speed figure is an "up to" result, and the score figures are averages for each skill group. Because PureVector is built from a player's own directional pattern, a recalibration after a period of training can be expected to reflect how that player's movement has changed.

PureVector is available on the SABRE v3 PRO PureVector Series, calibrated through Aimlabs and saved to the mouse directly. The series has six models across three shell materials, each in a symmetrical and an ERGO shape: ULTRALIGHT (37g), ULTRALIGHT ERGO (41g), MG (49g), MG ERGO (55g), CF (48g), and CF ERGO (54g). All six share the same PureVector calibration.
