Horizontal pixels are stretched across your monitor, making lateral targets appear wider and move faster.
Aspect Ratio Comparison & Stretch Multipliers
How common competitive resolutions scale when stretched across a standard 16:9 monitor:
| Aspect Ratio | Common Resolutions | Horizontal Stretch | Standard m_yaw | 1:1 Feel m_yaw |
|---|---|---|---|---|
| 16:9 Native | 1920x1080, 2560x1440 | 1.00x (No Stretch) | 0.022 | 0.022 |
| 4:3 Stretched | 1280x960, 1024x768 | +33.3% (1.333x) | 0.022 | 0.0165 |
| 16:10 Stretched | 1680x1050, 1440x900 | +11.1% (1.111x) | 0.022 | 0.0198 |
| 5:4 Stretched | 1280x1024 | +42.2% (1.422x) | 0.022 | 0.01547 |
🎯 Should You Change m_yaw?
When playing 4:3 stretched, many players ask whether to change m_yaw 0.0165 in their autoexec.
- ✗ Pro Disadvantage: Changing m_yaw alters your 3D muscle memory. A 180° flick now requires 33% more physical pad space, disrupting years of reflex aiming.
- ✓ Pro Recommendation: Over 90% of CS2 pros (like s1mple, NiKo, and m0NESY) keep
m_yaw 0.022at default and let their brain adapt to the faster horizontal visual motion.
🧠 Why Do Pros Use 4:3 Stretched?
If sensitivity feels distorted, why does the majority of professional Counter-Strike players prefer 4:3 stretched?
- • Wider Player Models: Character models appear 33% wider on-screen, making enemies feel easier to track and hit.
- • Maximum FPS: Lower pixel counts (e.g. 1280x960) reduce GPU load, giving peak 1% low frame rates on 240Hz+ monitors.
- • Tunnel Vision Focus: A narrower 73.74° horizontal FOV removes peripheral distractions, centering full focus on the crosshair.
Frequently Asked Questions
Does playing 4:3 Stretched actually change your mouse sensitivity?
Technically, no. Your 360-degree physical turn distance (cm/360) remains 100% identical because mouse input rotates the 3D game camera by degrees, not screen pixels. However, because 4:3 is stretched horizontally by 33.3% across your 16:9 monitor, horizontal player models and crosshair movements visually appear to move 1.333x faster across your display.
Should I change m_yaw to 0.0165 when using 4:3 Stretched?
In CS2 and Source engine games, default m_yaw is 0.022. Changing m_yaw to 0.0165 (0.022 * 3/4) restores a 1:1 visual ratio between horizontal and vertical screen travel. However, doing so increases your physical horizontal cm/360 by 33%, meaning you must physically move your mouse 33% further to execute a 180 or 360 turn. Most professional players recommend keeping m_yaw at 0.022 to preserve muscle memory.
How do I calculate 4:3 Stretched to 16:9 sensitivity compensation?
To keep the same visual screen-distance feel without changing m_yaw, divide your 16:9 sensitivity by 1.333 (for 4:3 stretched) or multiply by 0.75. For 16:10 stretched, the stretch factor is 1.111 (multiply sensitivity by 0.90).
Does Valorant support true 4:3 Stretched?
No. Riot Games locked Valorant's in-game Field of View (FOV) to 103 horizontal degrees on 16:9. Running 4:3 in Valorant only stretches the HUD, crosshair, and UI menus; character models and game worlds maintain the exact same rendering aspect ratio, so sensitivity never changes.
