Why does my game crash when changing settings?

Usually because applying a setting, a graphics change, a resolution switch, an option, triggers a crash on certain devices or configurations your code does not handle. Settings crashes are often device-specific or configuration-specific: changing a graphics setting can crash on a particular GPU, switching resolution can crash on certain displays, or applying an option can hit a code path that fails under some conditions. These are invisible on your test device (where the setting change works) and only show on the affected devices. To find them, capture the crashes with device context, settings crashes show a stack trace pointing at the settings/apply code and often cluster on certain devices or configurations. Bugnet captures crashes with device context and stack traces, so you can see the crashes from settings changes (the stack trace in settings code) and which devices they cluster on, revealing the device-specific settings issues your hardware does not surface, so you can fix the settings handling for the affected configurations and verify per version the crashes stopped, ensuring players can change settings without crashing the game across the devices they use.

Why don't my game's settings save?

Because settings persistence is failing, the settings are not being written, are written incorrectly, or are not loaded on launch, so they reset to defaults each time. Settings that do not persist are a common, annoying bug: players configure the game, but their settings reset every launch, forcing them to reconfigure. The cause is a persistence failure: the settings are not being saved (a write error, settings not actually persisted), saved incorrectly (corrupt or unreadable), or not loaded on launch (the game does not read the saved settings, or reads them wrong), so the game falls back to defaults. To find the cause, capture the errors around settings save and load. Bugnet captures the errors and crashes around settings persistence with context, so you can see if settings are failing to save or load (a persistence error, a load failure) and fix the issue, ensuring settings are written and read reliably (and safely, like saves, with proper handling), so players' settings stick across launches rather than resetting, eliminating the friction of reconfiguring the game every time.

What are good default settings for a game?

Sensible defaults that make the game run well out of the box across devices, especially performance defaults scaled to the device rather than set too high for lower-end hardware. Poor defaults are a common mistake: performance defaults set for high-end hardware (or your dev machine) make the game run badly by default on the lower-end devices many players use, giving a poor first impression before players find the settings to lower them, and some never do, just churning. Good defaults make the game look and run well immediately: performance settings appropriate to the device (ideally auto-detected or conservative enough to run well on common hardware), with the option to increase quality for capable devices, and other defaults (controls, audio, accessibility) set to sensible, broadly-comfortable values. The goal is that a player who never touches the settings has a good experience. Bugnet captures performance data with device context, so you can see how your default settings actually perform on real devices (including low-end ones), revealing whether the defaults are too demanding, and adjust them so the game runs well out of the box across the hardware range, ensuring a good default experience rather than one that runs badly until players find and lower the settings.

Common Game Settings Mistakes

Quick answer: The biggest game settings mistakes are settings crashes, settings not persisting, bad defaults, and no scalable options, fix these by making settings reliable, persistent, and well-defaulted.

Settings let players tailor the game, but common mistakes make them crash, reset, or fail players. Here are the most common game settings mistakes and how to avoid them.

Settings Changes That Crash

A common settings mistake is changes that crash the game, applying a graphics setting, a resolution change, or an option that crashes on certain devices. A settings crash frustrates players trying to configure the game and can lock them out.

The fix is handling settings changes robustly across devices. Bugnet captures the crashes from settings changes with device context, so you can see which settings crash on which devices (the stack trace pointing at the settings code) and fix them, ensuring players can configure the game without crashing.

Settings That Do Not Persist

A second mistake is settings that do not persist, resetting to defaults every launch, so players have to reconfigure each time. Non-persistent settings are an annoying bug that makes players re-do their preferences repeatedly.

The fix is persisting settings reliably (and safely, like saves). Bugnet captures the errors and crashes around settings persistence, so you can see if settings are failing to save or load (a persistence error) and fix it, ensuring players' settings stick across launches.

Defaulting Settings Poorly

A third mistake is poor defaults, especially performance defaults set too high for many devices, so the game runs badly by default on lower-end hardware. Bad defaults give a poor first impression before players find the settings.

The fix is sensible defaults, especially scaling performance defaults to the device. Bugnet captures performance data with device context, so you can see how the default settings perform on real devices (including low-end ones) and adjust the defaults so the game runs well out of the box across hardware.

Avoid the big game settings mistakes: settings crashes, settings not persisting, bad defaults, and no scalable options. Make settings reliable, persistent, and well-defaulted.
