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.

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.
