After a CS2 patch, confirm your in-game sensitivity and zoom sensitivity multiplier, check the mouse DPI/profile, and repeat the same swipe in a practice map. Frame-time spikes, a changed display mode, or mouse software switching profiles can change perceived aim even when the sensitivity number has not changed.

Try these steps in order
Each check is reversible and designed to tell you something useful. Expand the details if you need the full explanation.
Screenshot mouse sensitivity and zoom sensitivity ratio before changing anything.
Gaming mouse software can load per-game profiles or respond to hardware DPI buttons.
Practice on a fixed point with a marked mousepad distance.
A resolution change can alter perceived speed without altering angular sensitivity.
Extremely high polling settings or interfering utilities can produce hiccups in certain systems.
Let tests prove which variable changed.
A quick physical sensitivity check
Use this short reference to interpret your results before making another change.
Record DPI and in-game sensitivity before the test.
Stand still and face a distinctive wall mark.
Move the mouse a fixed distance across the pad.
Repeat after changing only one suspected variable.
Why this happens
Perceived sensitivity is the combined experience of angular movement, frame delivery, zoom, and input feel. A patch can affect performance or settings persistence without necessarily changing sensitivity mathematics.
Can change with mouse profiles.
Controls turn distance for raw mouse movement.
Late frames can make stable inputs feel heavy.
Important limits and safe checks
Do not make undocumented registry edits or install input “fixers” to chase a feeling. Protect your baseline values first and use repeatable tests.
Frequently asked questions
Short answers for players looking for this specific problem.
Did Valve secretly change mouse sensitivity?
A changed feeling alone does not demonstrate that; first check actual values and repeatable turn distance.
Can a changed resolution affect mouse feel?
Yes, the visual perception can change even if angular sensitivity does not.
Why is AWP zoom affected separately?
Zoom sensitivity is a distinct setting from ordinary hip-fire sens.
Does Windows pointer speed change CS2 aim?
CS2 uses its own mouse input path, so Windows desktop pointer movement is not a dependable test of in-game sensitivity.
Is reinstalling the game useful?
Not before checking DPI profiles, settings and frame-time behavior.
