What is stretched resolution in gaming?

Stretched resolution is when a player uses an aspect ratio (like 4:3 or 16:10) that is narrower than their native screen aspect ratio (usually 16:9) and expands it horizontally to fill the display. This stretches the visual models horizontally, making targets look wider and easier to hit.

Does stretching your resolution affect mouse sensitivity?

Yes and no. Physically, the angular rotation (degrees turned per inch of mouse movement) remains exactly the same. However, because the horizontal image is stretched across a wider space, the horizontal movement appears faster. This creates a perceived mismatch between vertical and horizontal speed.

What is m_yaw and why change it?

m_yaw is the console command in games like Counter-Strike (CS2/CS:GO) that controls horizontal mouse speed. By adjusting m_yaw from its default value (0.022) to a lower value (like 0.0165 for 4:3 on a 16:9 monitor), you can make the horizontal movement speed match the vertical movement speed on your screen.

Should I change m_yaw for stretched resolution?

Generally, most pros and aim coaches recommend NOT changing m_yaw. Keeping m_yaw at 0.022 preserves your physical muscle memory for angular rotation, which is identical between native and stretched. Adjusting m_yaw breaks vertical-to-horizontal uniformity (your mouse moves slower horizontally than vertically for the same physical movement).

m_yaw Adjustment

To make your horizontal sensitivity match your vertical sensitivity on screen, set your console command m_yaw to the adjusted value below.

Reset to Default (16:9 / Normal):

m_yaw 0.022

⚠️ Muscle Memory Advisory

Changing your m_yaw or horizontal sensitivity makes horizontal movements cover less angular distance in the 3D world than vertical movements for the same physical hand travel.

This breaks your vertical-to-horizontal uniformity.
Drawing perfect circles or executing diagonal flicks will feel skewed.
Vertical recoil control will require a different muscle movement scale than horizontal adjustments.

Recommendation: Leave sensitivity settings at default and allow your brain to naturally adapt to the horizontal stretch.

How Stretched Resolutions Affect Mouse Aim

When you select a non-native aspect ratio like 4:3 (e.g. 1280x960) or 5:4 (e.g. 1280x1024) and set your monitor or GPU to stretch the display to fill the screen, the image is stretched horizontally. Because of this, elements on your screen move faster horizontally than they do vertically.

Physically, your 3D sensitivity is exactly the same. Your mouse will still turn the exact same number of degrees in the game engine per centimeter or inch of physical movement. However, because your field of view (FOV) is compressed and stretched, the target moves faster on screen, making your mouse movement feel faster horizontally.

The Muscle Memory Dilemma: To Change or Not to Change?

There are two schools of thought on how to handle sensitivity on stretched resolution:

1. Keep Settings Default (Recommended):
Most esports professionals and aim theory experts recommend leaving your settings alone. If you do not change your sensitivity or m_yaw, your physical muscle memory for turning and aiming remains 100% consistent with native resolution. Yes, horizontal targets look faster, but your hands already know the physical distance to move to cover that angular distance.
2. Adjust Horizontal Sensitivity (m_yaw):
If the visual mismatch is highly distracting and you want horizontal mouse movements to cover the same screen pixels as vertical ones, you can adjust your horizontal multiplier (or m_yaw in Source engine games). This fixes the screen-space speedup but introduces a physical mismatch: you will now need to move your mouse physically further horizontally than vertically to turn the same number of degrees in-game.

Stretched Resolution Settings by Game

Counter-Strike 2 & CS:GO

CS2 is the most popular game for stretched resolution. The console command m_yaw defaults to 0.022. When you play 4:3 stretched on a 16:9 monitor, the horizontal image is stretched by 1.333x. By setting m_yaw 0.0165 (which is 0.022 / 1.333), your horizontal and vertical screen speeds will feel identical.

Valorant

Valorant uses a strict lock on horizontal FOV. If you run a 4:3 resolution in Valorant, the game stretches the UI/HUD elements, but the 3D world remains rendered at a standard 16:9 aspect ratio. This means models are not physically wider on screen, and your actual 3D aim speed is identical. Valorant does not support m_yaw adjustments.

Apex Legends & Call of Duty

Apex Legends stretches both the 3D environment and HUD elements. There is no built-in config command to change horizontal sensitivity independently. If you want a 1:1 screen feel, you would need to adjust the X-axis DPI of your mouse (using software like Razer Synapse or Logitech G HUB) which is generally not recommended.
