L4D2 to CS2 Sensitivity

CS2 sensitivity =
L4D2 sensitivity × 1

Both games turn 0.022° per mouse count, so the same sensitivity at the same DPI gives the same turn.

L4D2 to CS2 sensitivity chart

L4D2 values from 0.40 to 3.20, the CS2 value with the same 360° distance, and how far you move the mouse for one full turn at 400, 800 and 1600 DPI.

Method: 360° distance. The CS2 column is the same at every DPI; only cm/360 changes with DPI.

How this conversion works

One multiplier from two yaw values

L4D2 → CS2 × 1

L4D2 turns 0.022° per mouse count at sensitivity 1. CS2 turns 0.022°. The ratio of the two is the multiplier.

CS2 sensitivity: CS2 = L4D2 × 0.022 ÷ 0.0221.114 × 1 = 1.114
Back to L4D2: L4D2 = CS2 × 0.022 ÷ 0.0221.114 × 1 = 1.114
cm per 360°: 2.54 × 360 ÷ (yaw × sens × DPI)914.4 ÷ (0.022 × 1.114 × 800) = 46.64 cm
eDPI: sensitivity × DPIL4D2 891, CS2 891 at 800 DPI. eDPI only compares players inside one game.

Yaw

Degrees per mouse count

L4D20.022°

CS20.022°

Both games turn 0.022° per count, so the same sensitivity gives the same turn.

360° distance

A length you can measure

360 ÷ (0.022 × 1.114) = 14,689 counts
14,689 ÷ 800 DPI = 18.36 in = 46.64 cm

Divide 360° by the angle per count to get counts per turn, then divide by DPI to get inches.

Other match methods

360° distance or monitor distance

The chart matches 360° distance, which does not depend on field of view. Monitor distance matching (0%, 56.25%, 75%, 100%) depends on the FOV you set in L4D2. The TrueSens app reads your FOV and shows every method side by side.

What this page can't do

This page is a reference chart. The parts that need your PC are in the free Windows app:

Reads your current sensitivity from L4D2's config file, so you don't have to look it up.
Writes 1.114 into CS2 (cs2_user_convars_0_slot0.vcfg) and keeps a backup you can restore.
Measures your real DPI. An 800 DPI mouse can really be 826, which changes your cm/360.
Draws 46.64 cm at true size on your screen after a one-time bank-card calibration.
Blind A/B feel test between your old feel and the converted CS2 value.

FAQ

L4D2 to CS2 sensitivity questions

How do I convert L4D2 sensitivity to CS2?

Use the same value. L4D2 and CS2 both turn 0.022° per mouse count, so L4D2 1.114 is CS2 1.114 at the same DPI.

What is 1.114 L4D2 sensitivity in CS2?

1.114 at any DPI. At 800 DPI both settings turn you 360° with 46.64 cm of mouse movement.

Does DPI change the L4D2 to CS2 conversion?

No. The multiplier is the same at 400, 800 or 1600 DPI as long as you use the same DPI in both games. DPI only changes your cm/360.

Should I match 360 distance or monitor distance from L4D2 to CS2?

360 distance keeps full turns and flicks identical and does not depend on field of view, so the chart on this page uses it. Monitor distance matching depends on the FOV you play with; the TrueSens app reads it from your settings and gives you that value too.

How do I set my converted sensitivity in CS2?

Open the CS2 console and enter sensitivity 1.114, or set it in the game's mouse settings. The free TrueSens app for Windows can write the value into the CS2 config for you and keeps a backup.

How do I convert CS2 sensitivity to L4D2?

Use the same value: CS2 1.114 is L4D2 1.114.
