How do I reduce my game's memory usage?

Find what holds the most memory on real devices (usually textures, audio, caches, and loaded-but-unused assets), unload what isn't currently needed (free assets when leaving areas, clear caches, avoid loading everything up front), compress large textures and audio (which often dominate the footprint), stream content instead of loading it all up front, and check for a memory leak that grows usage over time. Then verify the footprint dropped and out-of-memory crashes stopped on the devices that were struggling.

Why does reducing memory usage matter?

Because a bloated memory footprint causes out-of-memory crashes on lower-memory devices (when your usage exceeds their RAM, the OS kills the game), so reducing it lets your game run on more devices and avoid those crashes. High memory use can also hurt performance. Since a meaningful share of players are on memory-constrained devices, reducing your footprint directly widens your game's compatibility and reach, while preventing the OOM crashes that drive away those players.

What uses the most memory in a game?

Usually a few categories: textures, audio buffers, cached data, and assets that are loaded but not currently needed. Code is comparatively small. Measuring on real devices reveals which holders dominate your footprint, so you can free meaningful amounts by unloading and managing those (and compressing the large textures and audio, which are often stored at higher quality than needed) rather than nibbling at minor allocations. A memory leak can also inflate usage over time, so check for that too.

Tips for Reducing Memory Usage

Quick answer: Find what holds the most memory on real devices, unload what isn't currently needed, compress large textures and audio, stream instead of loading everything up front, and check for leaks.

Reducing memory usage lets your game run on lower-memory devices, avoid out-of-memory crashes, and perform better. It comes down to holding less. Here are practical tips for reducing memory usage.

Find What Holds the Most Memory

The first tip: find what's actually using memory, usually a few categories dominate: textures, audio buffers, cached data, and loaded-but-unused assets. Finding the biggest holders on real devices tells you where the footprint is, so you free meaningful amounts rather than nibbling.

Bugnet captures performance and memory-related crash data from real sessions, so you can see where memory pressure concentrates. Knowing what holds the memory is the start of reducing it.

Unload What Isn't Needed and Compress

The core tips: unload what you don't currently need (free assets when leaving areas, clear caches, don't load everything up front) and compress large assets (textures and audio often dominate the footprint and are stored at higher quality than needed). These free the most memory.

Bugnet helps you see which situations hit memory pressure, so you target the unloading that matters. Holding only what the current moment needs, and compressing the big assets, is the core of a small footprint.

Check for Leaks and Verify

The final tips: check for a memory leak (memory that grows over a session, never freed), which inflates your footprint over time, and verify your reductions on the devices that hit out-of-memory crashes. Confirming the footprint dropped and OOM crashes stopped tells you the reduction reached the players who needed it.

Bugnet captures memory-related crashes by device and over sessions, so you can find leaks and verify fixes. So reduce memory usage by finding what holds memory, unloading and compressing, and checking for leaks, verified on the devices that were running out of memory.

Find what holds the most memory on real devices, unload what isn't needed, compress large textures and audio, stream instead of loading up front, and check for leaks. A bloated footprint causes OOM crashes on low-memory devices.
