Why XDefiant sens doesn't match Left 4 Dead 2

At 0.4 sens on 800 DPI, XDefiant sweeps 129.89 cm across a full 360°. To reproduce that exact arm motion in Left 4 Dead 2, you need sens 0.4 — about 1.00× your XDefiant number. Nothing changed except Left 4 Dead 2's yaw of 0.022 vs XDefiant's 0.022; the centimeters of mouse travel stay the same.

How to apply the converted sensitivity in Left 4 Dead 2

Open Left 4 Dead 2's settings, paste the converted sensitivity into the sens field and keep your 800 DPI if that matches how you play XDefiant. Run a 360° check on a practice map: the mouse sweep should cover roughly 129.89 cm on your pad — the same distance as in XDefiant. Only start tuning if the sweep feels off, never before the 360° check.

Common mistakes when converting XDefiant to Left 4 Dead 2

  • Copying the sens without matching DPI

    A converted XDefiant-to-Left 4 Dead 2 number is tied to the DPI you used during conversion. If your Left 4 Dead 2 mouse profile runs a different DPI, the math no longer holds — use Sens Converter's 'different DPI' toggle instead of eyeballing.

  • Trusting eDPI across engines

    Matching eDPI between XDefiant and Left 4 Dead 2 does not give matching turn speed, because their yaws are 0.022 and 0.022. Always compare cm/360° (or in/360°), not eDPI, when swapping games.

  • Ignoring scoped and ADS overrides

    XDefiant and Left 4 Dead 2 each apply their own scoped / ADS multiplier on top of the base sensitivity. Converting the base is step one — confirm the per-zoom multiplier in Left 4 Dead 2 separately, otherwise scoped aim will feel wrong even with a perfect hipfire match.

XDefiant → Left 4 Dead 2 FAQ

Why is my converted Left 4 Dead 2 sens different from my XDefiant number?+

Left 4 Dead 2 has a yaw of 0.022 compared to XDefiant's 0.022. Their ratio is about 1.00×, so Sens Converter multiplies your XDefiant sens by that factor to keep cm/360° identical. The raw number looks different, but the arm motion is the same.

Should I keep the same DPI in XDefiant and Left 4 Dead 2?+

Yes, when possible. Keeping DPI identical means only the in-game multiplier changes, which is the cleanest switch. If you run different DPI in Left 4 Dead 2, enable 'different DPI' in the converter and it absorbs the extra math.

How many decimals should I use in Left 4 Dead 2?+

Left 4 Dead 2 accepts at least 3 decimals; 4-6 is common. Sens Converter outputs enough precision that rounding to 3 decimals keeps the 360° error below one millimetre on a typical 800 DPI setup.

Does FOV affect XDefiant to Left 4 Dead 2 conversion?+

For the base sensitivity, no — sens is independent of FOV in both engines. If you use a 0% MonitorDistance or similar scaling mode in either game, convert at the FOV you actually run in-game.
