Games Like FPS Performance Lab
Not a game and not an FPS booster. FPS Performance Lab is a mouse aim test for shooter players: in about 10 minutes it shows why you miss – overshooting, stopping too early or losing moving targets – then gives you one thing to fix and a retest to see if it helped.

Missing shots? Find out why.
Most aim trainers just give you more drills. FPS Performance Lab first finds out why you miss. In about 10 minutes you'll see how you really move your crosshair and which habit is costing you the most hits.
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
How it works
No more changing your DPI, sensitivity and routine on the same evening and guessing what worked.
What we check
Reaction time and recoil control are shown separately – fast reflexes won't hide sloppy mouse control.
Not just a score – see where it comes from
Everything in one place
It never touches your games
FPS Performance Lab is a separate program. No overlay, no reading game memory, no aiming for you, and it doesn't change anything in your games or system. It only reads your mouse while its own window is active. All your results stay on your computer.
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”.
