About This Software

Find out why you miss – in a test, in a 3D arena and in your own matches

Most aim trainers just give you more drills. FPS Performance Lab first finds out why you miss. In a few minutes you'll see how you really move your crosshair and which habit costs you the most hits. Then you train it in a 3D arena and check it in real matches.

Instead of a vague “aim better”, you get something concrete, for example: “In 14 of 32 movements you go past the target.”

What it is – and what it isn't

• It is a mouse aim test, a 3D training arena and a match analysis tool for shooter players.

• It isn't an online shooter – no opponents, no story. You train on targets and the app measures how your hand moves.

• It isn't an FPS booster – it doesn't raise your frame rate or change your PC or game settings. “FPS” stands for first-person shooters.

• You need a mouse and a few minutes for your first result.

How it works

• Take the test – always under the same conditions, so results can be compared fairly.

• See what's off – an Aim Score from 0 to 100, how much it normally swings, and the one thing that matters most, with a replay of your own movement.

• Follow the plan – a few short sessions picked for exactly your problem.

• Check the result – the retest tells you straight: it helped, it's within your normal swing, it got worse, or it's too early to tell.

Train in a 3D arena

Aim training runs in a 3D arena built with Unreal Engine 5, right inside the app window. It turns like your game – with the sensitivity and field of view of the game you play – and reads your mouse straight from Windows Raw Input.

• Flick – one smooth movement onto the target, click only after you stop.

• Precision · stop on target – slow down, stop, then click on small targets.

• Reaction – click the moment the target appears.

• Tracking – stay on a target that moves and changes direction.

Each exercise first shows the model movement – the crosshair path and its speed.

Your matches, analysed

Play as usual. FPS Performance Lab records how your hand moves in a real match and describes it in plain words.

• Match summary – one headline, up to three observations with evidence and clips, and one thing to try in your next match.

• Deaths without a shot are counted separately – bad positioning isn't blamed on your aim.

• Match vs. your test – does the habit from the test show up in a real game? Compared only at the same DPI and sensitivity.

• Player card – every match against your own average.

Counter-Strike 2: recording starts and stops on its own, and kills, deaths, headshots and rounds come from Valve's official Game State Integration. Other games will follow once image analysis is ready.

What we check

• Flick – how quickly and cleanly you get to the target.

• Stopping – whether you stop on the target, go past it or fall short.

• Tracking – whether you stay on a target that moves and suddenly changes direction.

• Consistency – whether you aim the same way from your first attempt to your last.

Reaction time is shown separately – fast reflexes won't hide sloppy mouse control.

Sensitivity without guessing

• Converter between games – CS2, Valorant, Apex Legends, Overwatch 2, Call of Duty, Fortnite, Rainbow Six Siege and more.

• DPI change and eDPI / cm/360 – calculated with each game's formula.

• Find sensitivity – five short rounds, slower vs faster. If nothing clearly wins, the app tells you to keep your current sens.

• Game profiles – sensitivity, resolution and measured turn saved for each game.

And more

• Vision training – spot targets faster and see more out of the corner of your eye.

• Pre-match warm-up – a ready-made routine before you play.

• Challenges and Steam leaderboards.

• Progress history with retests and a PDF report for your coach or friends.

It never touches your games

FPS Performance Lab is a separate program. No overlay, no reading game memory, no aiming for you, and it changes nothing in your games or system. It reads your mouse in the background only while a match is being recorded. Video recording is optional and clips stay on your computer. Anonymous match numbers are shared for player comparison only if you agree.

17 languages

The app automatically uses the language you use on Steam. You can change it any time in Settings.

Don't train more. Train what matters.

No “magic sensitivity”, no overnight miracles. You get a reliable measurement, a clear tip and an honest answer about whether your change helped – even when that answer is “no”.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some store page images (backgrounds and key art behind the logo) were created with the help of generative AI and then combined with the original logo. Translations of the app and store page into languages other than Polish were prepared with the help of AI. All measurements, scores and recommendations in the app are calculated by fixed algorithms - no AI generates content while you use the app.
