If you've ever switched from Valorant to CS2, or jumped into Apex after months of Warzone, you already know the pain: your aim feels completely off. Your crosshair overshoots. Flicks don't land. Everything feels slippery or sluggish. And then you spend the next hour tweaking sensitivity numbers by feel — guessing, dying, adjusting, repeating.
The problem isn't your aim. It's your settings. Every FPS game uses a different internal sensitivity multiplier, which means "0.4 in Valorant" and "2.0 in CS2" don't feel even remotely the same. Converting between them isn't guesswork — it's math. And SensLab does that math for you, instantly and for free.
What Is SensLab?
SensLab is a free, precision sensitivity converter and eDPI calculator built specifically for competitive FPS players. It lets you sync your exact mouse feel across every major title — so the muscle memory you've built over hundreds of hours in one game carries directly into the next.
It supports all the games that matter:
- Valorant
- CS2 / CS:GO
- Apex Legends
- Fortnite
- Warzone
- Overwatch 2
- Rainbow Six Siege
- Rust
- Battlefield 2042
- Splitgate, TF2, Quake Champions, and more
No more guessing. SensLab calculates your exact equivalent sensitivity in every supported game simultaneously, using verified multipliers — the same numbers the pros use.
🎯 Tab 1: Sensitivity Converter
The core of SensLab is its sensitivity converter. Here's how it works: every FPS game processes mouse input using a different internal multiplier. Valorant uses 0.07, CS2 uses 0.022, Fortnite uses 0.5588. Those numbers mean nothing in isolation — what matters is the physical distance your mouse travels to complete a full 360-degree turn, measured in centimetres. That's your cm/360, and it's universal across every game.
Enter your game and current sensitivity in SensLab, and it:
- Calculates your cm/360 (the universal aim benchmark)
- Shows your converted sensitivity in the target game
- Displays your equivalent sensitivity in all 12 supported games simultaneously — one lookup, every game covered
- Shows inches/360 alongside cm/360 for players who prefer imperial measurements
The result is that your muscle memory transfers perfectly. The flick that hits a Vandal headshot in Valorant will feel identical when you pick up an AWP in CS2.
Pro tip: TenZ (one of Valorant's most recognized pros) plays at 800 DPI and 0.408 in-game sensitivity — an eDPI of 326. That's considered "low sens" by most standards. s1mple, CS2's all-time great, plays at 400 DPI × 3.09 = 1,236 eDPI. There's no single right answer, but knowing your number is the first step to dialing yours in.
📊 Tab 2: eDPI Calculator
eDPI — effective DPI — is the single number that actually describes your sensitivity. It's calculated as: mouse DPI × in-game sensitivity. It cuts through all the confusion of comparing setups with different hardware.
A player running 400 DPI at 2.0 sensitivity has the same eDPI (800) as a player running 800 DPI at 1.0 — they feel identical in-game. eDPI is the language pros use to communicate sensitivity, because it's hardware-agnostic.
SensLab's eDPI calculator takes your DPI (with a preset dropdown of the most common values, or a custom input), your game, and your in-game sensitivity — and outputs:
- Your eDPI
- Your cm/360 for that game and hardware combo
- A sensitivity tier rating (Low / Mid-Low / Mid-High / High) with a visual bar
- A pro player reference table with real eDPI numbers from TenZ, s1mple, Shroud, Bugha, ZywOo, Sinatraa, and more
The pro table alone makes SensLab worth bookmarking. Instead of hunting through Reddit and pro settings databases, you have it right there on the same page as your calculator.
🖱️ Build the Setup That Makes SensLab Matter
Dialing in your sensitivity is only half the equation. The other half is your hardware. A precision converter is only as good as the mouse executing those movements. Here are three Amazon picks that pair perfectly with a properly calibrated SensLab setup — all available on Amazon with fast shipping.
The mouse used by more pro FPS players than any other. At just 60 grams, the Superlight 2 is light enough to make low-eDPI flick shooting effortless — no fatigue, no friction, no drag. The HERO 2 sensor delivers 44,000 DPI with zero smoothing or acceleration, which means the sensitivity you set in SensLab is exactly what you get. 8kHz wireless polling and 95-hour battery make it as reliable as a wired mouse at tournament weight.
View on Amazon →The Viper V3 Pro is the benchmark for symmetrical FPS mice — the shape that works equally well for claw, palm, and fingertip grip. At 54 grams with 8,000 Hz HyperPolling and Razer's Focus Pro 35K optical sensor, it's the preferred weapon for players who prioritize fast, controlled flicks in games like Valorant and CS2. If you run a low-to-mid eDPI and rely on wrist-based aiming, this is the one.
View on Amazon →The most important part of dialing in a low sensitivity is having the space to use it. With over 10 million sold, the QcK XXL (35" × 16") is the mousepad of choice for pros at every major esports event. Its high thread-count micro-woven cloth surface is optimized for both optical and laser sensors, giving you consistent tracking whether you're dragging a full-arm swipe or making subtle wrist adjustments at high eDPI. No slipping, no bunching, no excuses.
