Optimize Performance

>-

Mobile devices have tighter resource constraints than desktop or web. Understanding the mobile scene limits and how to preview them helps you ship a scene that runs smoothly for the widest audience.

Mobile Scene Limits

The table below shows the limits enforced when running on mobile. Reaching a soft limit triggers a warning in the performance panel; reaching a hard limit blocks the scene from loading.

Metric Soft Limit Hard Limit
Triangles 1,000,000 1,200,000
Entities 4,800 6,000
Meshes (bodies) 2,400 3,000
Geometries 1,000 2,000
Materials 400 500
Textures 400 500
Colliders 1,200 1,500
Content size 120 MB 150 MB
External content 40 MB 50 MB
Memory (process RSS) 1,638 MB 2,048 MB
Draw calls 1,000 2,000
Performance (higher is better) 90% 85%

Preview Mobile Performance

You can check your scene’s mobile performance directly from Creator Hub without deploying to a physical device.

  2. Select Preview > Show QR Code for Mobile

Keep Performance above 90% on High Graphics

The Performance value is a percentage of the FPS budget set by the active graphic profile. A score of 100% means the scene is hitting the full FPS target.

Always test on a mid-spec device like the Samsung Galaxy A54 and aim for a Performance score above 90% on the High graphic profile. This ensures a smooth experience for the majority of mobile players. See Hardware Requirements for reference devices.

You can change the graphic profile from In-Game Menu → Settings → Graphics → set Dynamic Graphics to Off → switch Profiles.
