Mouse Tracking Only Fails in One Game
When mouse tracking appears normal everywhere except one game, the application context becomes an important part of the investigation. That pattern does not by itself identify a hardware fault.
A practical approach
Record the game profile, raw-input option, aiming modifiers and frame behavior. Compare a simple repeatable scene before and after one documented setting change. Disable only optional tools you understand and use official support guidance for the installed version. Keep a working default so the experiment can be reversed without losing the original configuration.
A profile is useful only when you know which one is active
Device and application profiles can store different sensitivity or button settings, but switching behavior varies by product. Some options may depend on software running, while others may be stored on the device. Do not assume every model supports the same arrangement.
Name profiles clearly and record the important values in plain text. Test whether the intended profile remains active after restarting the application or reconnecting the mouse. Keep automatic switching simple until you understand it. If behavior changes unexpectedly, check the active profile before treating the issue as a sensor or connection failure. A small number of well-documented profiles is generally easier to manage than many near-duplicates with unclear purposes.
Raw input is a software path, not a complete latency guarantee
Applications can obtain mouse movement through different input paths. Raw input exposes device movement information in a way that differs from ordinary cursor handling, but the application's own processing still matters. A raw-input option should not be interpreted as a promise that every setting, delay or compatibility issue disappears.
Check the documentation for the specific game or application and record the selected mode. Keep desktop pointer behavior separate from the movement observed in that application. When troubleshooting, change one relevant option and compare the same task. Avoid assuming that a similarly named option behaves identically in every title or software version. The practical goal is to understand the actual input route rather than use a label as a substitute for testing.
Frame time and mouse reports are different clocks
Display refresh, rendered frame rate and mouse reporting frequency describe different parts of a system. Their numerical values should not be treated as interchangeable. A monitor refreshing at 144 Hz has an ideal refresh interval of about 6.94 ms, while a mouse reporting at 1,000 Hz has a nominal report interval of 1 ms.
Those figures do not simply add into a universal latency prediction, because timing and processing throughout the system matter. When comparing setups, record both frame behavior and input settings. A high reporting rate cannot create frames the game does not render, and a fast display does not establish the quality of every mouse input. The useful approach is to understand each measurement's role rather than select a matching number by appearance.
An example to work through
A profile that loads an unexpected sensitivity or button assignment can make one game feel broken while desktop use remains normal. Checking the active profile may reveal more than swapping devices immediately.
What to check
- Confirm the profile that actually loads.
- Record input and aiming options.
- Retain a reversible default configuration.
