What causes loading times growing over updates?

Each update adds content and code that loads at startup, and without keeping loading optimized, the cumulative load grows until startup and level loads become noticeably slow.

How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Fix Loading Times Growing Longer Over Successive Updates

Quick answer: Profile what loads at startup, load only what is needed up front, stream and defer the rest, and keep an eye on load times across updates.

Loading times growing over updates is accumulating startup work. Trimming it fixes it. Here is how.

How to fix it

1. Profile what loads

Profile the startup and level loads to see what is loaded and how long each part takes. Over updates, more content and systems get loaded up front; the profile shows what has accumulated and what to trim.

2. Load only what is needed up front

Load only what the first screen or level actually needs at startup, deferring and streaming the rest. As content grows, front-loading everything makes loads creep up; loading on demand keeps them flat.

3. Track load times across updates

Monitor load times as a metric across updates so a regression is caught when it is introduced, not after it has crept up over many versions. Keeping loading optimized is ongoing, not a one-time fix.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

The errors you never hear about are the ones quietly costing you players. Visibility turns them into a worklist.
