How do I improve my game's load times?

Load less before the player needs it (stream assets as required and defer non-essential content to the background, so the player starts sooner), compress assets sensibly to cut I/O, parallelize loading where possible, and measure real load times on the slow devices and storage players use (not just your fast machine). How much you load up front usually matters more than raw asset size, so loading less is the biggest lever.

Why are my load times fine for me but slow for players?

Because your dev machine has fast storage, so loads feel quick for you, while many players are on slower devices, older phones, hard drives, where the same load takes far longer. Long load times are often worse for players than your testing shows. The only way to know real load times is to measure them in the field across the devices and storage players actually use, then optimize for that reality rather than your fast machine.

What's the fastest way to cut load times?

Load less before the player needs it: stream assets as they're required instead of all up front, compress what you load to cut I/O, and defer non-essential content to the background. This gets the player started sooner, and how much you load up front usually matters more than raw asset size. Pair it with measuring real load times on the slow devices players use, so you target the screens where players actually wait and verify your improvements helped them.

Tips for Improving Load Times

Quick answer: Load less before the player needs it (stream assets, defer non-essential content), compress assets to cut I/O, parallelize loading, and measure real load times on the slow devices and storage players use.

Long load times test players' patience and cause drop-off at every screen. They're driven by how much you load and how, more than raw asset size. Here are practical tips for improving load times.

Load Less Before the Player Needs It

The biggest tip: load less up front. Much loading is loading everything when only some is needed immediately. Stream assets as the player approaches needing them, and defer non-essential content to the background, so the player starts sooner and the rest loads as needed.

Bugnet helps you see which loads and devices are slowest, so you prioritize the screens players actually wait at. Loading less before the player needs it usually cuts perceived load more than optimizing the loading code itself.

Compress Assets and Parallelize

The tip for cutting the load work: compress assets sensibly (smaller files mean less I/O and faster reads) and parallelize loading where possible (loading concurrently rather than serially). These reduce how long the loading itself takes for what you do load.

The right compression trade-off depends on your devices, so verify on real hardware. Compressing your biggest assets (usually textures and audio) and loading in parallel meaningfully cuts load times beyond just loading less.

Measure Real Load Times on Slow Devices

The final tip: measure real load times on the devices and storage players use, not just your fast machine. A player's older phone or hard drive is far slower, so your loads feel quick while theirs drag. Measuring reality tells you where players actually wait.

Bugnet captures timing data from real sessions across devices, so you see actual load times in the field. So improve load times by loading less up front, compressing and parallelizing, and measuring on real slow devices, verified where players actually wait.

Load less before the player needs it (stream and defer), compress to cut I/O, parallelize, and measure real load times on the slow devices players use. How much you load up front matters more than raw asset size.
