Missing shots? Find out why.
Aim trainers give you more drills. FPS Performance Lab tells you why you miss. A few-minute aim test shows exactly what goes wrong: do you fly past the target, stop too early or lose it when it moves? You get one thing to fix, then check whether it really helped.

What's new · version 1.11 · Oct 26, 2026
Match Analysis, movement replay and My mouse
A big update: besides the in-app test, you now measure your aim in a real match and see the test result as a replay of your own movement. It also includes every change from 1.9.3 and 1.10.
- Match Analysis (beta)Record a real match, then watch clips with a hand-speed chart. In CS2 also kills, headshots and deaths.
- Movement replayThe test result in four steps: one sentence, your hand movement, how often it happens and what to do next.
- My mouse & settingscm/360, crosshair step per mouse count, monitor Hz and polling rate. Settings per game.
- Your real DPIMeasure with a payment card in 30 seconds or with a ruler to about 1%.

New in version 1.11 · beta
Match Analysis – see your aim in a real game
Start recording and play a normal match. FPS Performance Lab records your mouse movement and, if you want, the screen. After the match you get the numbers and a few short clips with the moments worth watching in slow motion. Every clip comes with a hand-speed chart synchronised with the video and a plain description of what happened.
- Counter-Strike 2. In version 2.0 match analysis works in CS2: hand movement, video clips, plus kills, deaths and headshots from Valve’s official integration (GSI). Other games will come later.
- Hands off your game. No overlay and no reading game memory. Windows records the screen – the same mechanism as Xbox Game Bar.
- Stays on your PC. The recording stays on your computer; after the match only short clips are kept.
- Compare with other players. Optional and only with your consent: anonymous numbers from the match, and in return “better than X% of players” for each measure.
What else is in update 1.11
- Movement replay after the testThe result in four steps: one sentence, a replay of your hand movement, how often it happens and what to do next.
- My mouse & settingscm/360, crosshair step per mouse count, monitor Hz and polling rate. Settings per game, turn measurement in any game.
- Your real DPIMeasure with a payment card in 30 seconds or with a ruler to about 1%.
- A shorter first testAbout 3–4 minutes, stages advance by themselves, and a break no longer wipes the whole test.
- Motion analysis (beta)Your flick split into reaction, main movement and corrections – in millimetres, with a one-sentence reading for every chart.
Match Analysis (beta) is part of version 1.11 on Steam. The clips come from a real match played by the developer (CS2, deathmatch); the picture is cropped around the crosshair.

Version 2.0 – 3D arena and your matches
The most common note in reviews: the measurement is accurate, but it is hard to tell from the result what to do next. Version 2.0 fixes that: it tells you what to train, gives you a 3D training arena and checks the effect in your own matches. It is free for everyone who owns the app.
- 3D training arenaTraining built with Unreal Engine 5 inside the app window, with the sensitivity and field of view of your game: flick, precision, reaction and tracking.
- Match summary and clipsOne headline, up to three observations with evidence and short clips of key moments with your hand speed. CS2 records on its own.
- New DashboardYour score together with how much it swings on its own, one main problem and a replay of your movement from the last test.
- Plan and retestHow many sessions, what to train and when to retest. Verdict: improved, within noise, worse or inconclusive.
- Sens converter and “Find my sens”Convert sensitivity between games (CS2, VALORANT, Apex, Overwatch 2, CoD and more) and 5 rounds comparing two sensitivities.

From the first test, through the score and technique analysis, to training, warm-up and the retest. Polish voice-over with Polish captions.
How it works
One change. One retest. A clear answer.
- 01Take the test
A few minutes, always under the same conditions, so your results can be compared fairly.
- 02See what's off
An Aim Score from 0 to 100 and the one thing that matters most, shown on your own attempts.
- 03Change one thing
Your technique or a single setting. Not everything at once.
- 04Practice
Short drills picked for exactly your problem.
- 05Check the result
Take the test again. The app tells you straight: it helped, it didn't, or it's too early to tell. One lucky day won't be mistaken for progress.
Aim Score
Four pillars instead of one number
The Aim Score (0–100) is a weighted sum of four pillars of mouse control: Flick 25%, Stopping 30%, Tracking 30% and Consistency 15%. Reaction time is shown separately – fast reflexes won't hide sloppy mouse control.
02 / Endpoint control58/100
Stopping 30%
Whether you stop on the target, go past it or fall short. In this example it is the priority to work on.
03 / Continuous control72/100
Tracking 30%
Whether you stay on a target that moves and suddenly changes direction.
04 / Stability94/100
Consistency 15%
Whether you aim the same way from your first attempt to your last. High consistency makes a retest more meaningful.
- End-point map
- Where?
- Exactly where your crosshair stops compared to the center of the target.
- Direction and distance
- Which way?
- Which way and at what distance you miss most often.
- Honest assessment
- Confidence
- The app tells you when there isn't enough data to say anything yet – and what to do about it.
- Reaction time

01 / DIAGNOSIS
Aim Control Test
A few minutes under fixed conditions. Gives you an Aim Score and one priority.
Show details
Measures Flick, Stopping, Tracking and Consistency. Reaction time is shown separately. The app also rates measurement quality and says when there isn't enough data for a conclusion.
02 / TECHNIQUE
Technique Analysis
Shows what happens during each movement and which mistakes keep repeating.
Show details
Detects overshooting, undershooting, late braking, too many corrections and losing the target after a direction change. Replay your own movement and get a practice plan with a retest.
03 / PRACTICE
Aim Training
Short rounds of flicks, precision, tracking and reaction.
Show details
Pick the mode, level and round length, or start the training recommended by your plan. Training scores don't replace the full test – the retest checks progress.
04 / 3D ARENA
3D arena
Aim training and the aim test in a 3D arena (Unreal Engine).
Show details
The same exercises as in the app – flick, precision, tracking and reaction – in 3D space with in-game camera movement. Results are saved in the app.
05 / VISION
Vision Training
Spot targets faster and see more out of the corner of your eye.
Show details
Six areas: smooth pursuit, multiple object tracking, attention shifting, peripheral awareness, target search and distractor resistance. No eye tracker; not a medical diagnosis.
06 / READINESS
Pre-Match Warm-Up
A ready-made 5, 8 or 12-minute routine.
Show details
Activation, tracking, flick, precision, direction change and a readiness check. The plan can include your Dashboard priority. The warm-up does not change your Aim Score.
07 / SENSITIVITY
Control Optimizer
Compares three sensitivity options: 95%, 100% and 105%.
Show details
Short blocks under the same conditions, with variants hidden until the end. If no variant clearly wins, the app says so: keep your current sensitivity. Confirm a winner with a full test.
08 / SETTINGS
Game Profiles
Sensitivity, ADS, eDPI and cm/360 in one place, with conversion.
Show details
Presets for Counter-Strike 2, VALORANT, Battlefield, Call of Duty / Warzone, Apex Legends, Overwatch 2, Rainbow Six Siege and more. You apply changes in the game yourself – the app never writes game files.

Mouse sensitivity without guesswork
DPI, eDPI, cm/360 and ADS – what each parameter means
Game Profiles combine your setup with the sensitivity model of a specific game. A conversion is a starting point, not a guarantee of identical aim in every game.
Example: 800 DPI × 0.42 sensitivity = 336 eDPI. Compare eDPI only within the same game – different games use different sensitivity scales.
- DPI
- Mouse counts per inch of movement. Enter the DPI set on your mouse – the app does not program the sensor.
- Sensitivity and eDPI
- eDPI = DPI × in-game sensitivity. Useful for comparing two players' settings in the same game.
- cm/360
- How many centimeters you move the mouse to turn 360°. Requires a known conversion model for the game.
- ADS
- Sensitivity multiplier when aiming down sights. Its effect depends on the game and zoom.
- FOV
- Field of view changes how fast the picture seems to move. The same FOV number does not give an identical view across games.
- Raw Input
- The app measures mouse movement through Windows Raw Input in its own active window – in the background only during a match recording, a 3D arena round or a turn measurement you start yourself.
Safety and data
It never touches your games
FPS Performance Lab is a separate program. It reads your mouse while its own window is active. In the background only while you run a match recording, a 3D arena round or the in-game turn measurement yourself – and only until it ends. All your results stay on your computer – you can export, back up and delete them.
- No overlay.
- No reading game memory.
- No aiming for you.
- No changes to your games or system.
Version 2.0
17 languages
The app automatically uses the language you use on Steam. You can change it any time in Settings. PDF reports work in every language.
FAQ
FPS Performance Lab – questions and answers
Where can I get FPS Performance Lab?
On Steam, for Windows 10 and 11. It has been available since October 15, 2026; the current version is 2.0.
Is there a free demo?
Yes. Since November 1, 2026 there is a free FPS Performance Lab demo on Steam. You take the aim test and see your result before you buy the full version; some modules are locked in the demo.
How is it different from a regular aim trainer?
A typical aim trainer gives you more drills. FPS Performance Lab first measures how you really move your crosshair, points to the one thing that matters most, and then uses a retest to check whether your change helped. Detailed comparison: Aimlabs alternative.
Does it interact with my games or risk a ban?
FPS Performance Lab is a separate program. No overlay, no reading game memory, no aiming for you, and it does not change anything in your games or system. It reads your mouse while its own window is active. In the background only while you run a match recording, a 3D arena round or the in-game turn measurement yourself – and only until it ends.
Which games is it useful for?
The test measures your hand and mouse control, so the results apply to any FPS. Game Profiles include presets for Counter-Strike 2, VALORANT, Battlefield, Call of Duty / Warzone, Apex Legends, Overwatch 2 and Rainbow Six Siege, plus an option for other games.
Does it increase my frame rate (FPS)?
No. FPS in the name stands for first-person shooter. The program diagnoses and trains your aim; it does not increase frames per second.
Which languages are supported?
Version 2.0 has 17 interface languages. By default the app uses the language you use on Steam; you can change it any time in Settings.
Can it analyse my real matches?
Yes – that is Match Analysis (beta) in version 2.0 (example clip above, full description on the CS2 Match Analysis page). While recording, the app reads your mouse during the game and, if you want, the screen, but it does not touch the game itself: no overlay and no reading game memory. In version 2.0 it works in CS2, with kills, headshots and deaths from Valve’s official integration.
What does version 2.0 bring and what does it cost?
Version 2.0 has been on Steam since November 11, 2026 and is free for everyone who owns FPS Performance Lab. It adds a 3D training arena (Unreal Engine 5), a match summary with clips, a new Dashboard and a training plan with a retest.
Where are my results stored?
Results, history, profiles and PDF reports stay on your computer. You can export them and make backups.
