Performance Panel
Analyze and address possible performance issues in a scene to deliver the optimal device experience, every time.
What is performance?
Performance is optimizing a the components of a scene so that it works smoothly on the intended device. It’s a crucial part of the design process because, if a scene lags or glitches when played, it will not deliver the desired user experience.
Scene-level performance
It’s important to have a high-level picture of how a scene performs as it’s being designer. Below are the parts of the Performance Panel that help diagnose a scene’s general performance.
Preview Bar
The Performance warning icon (orange triangle next to Performance panel name) appears when the defined target device is at risk of being non-performant.
Performance overview
Get a broad overview of the scenes Geometry, Materials, Lighting, and other asset properties. Make sure nothing in the scene is selected, then open the Performance Panel.
Device dropdown
Select the device dropdown on the right side of the opened Performance Panel to get a high-level overview of how the scene performs for each device. Select a device to get suggestions on how to optimize your scene for a specific device in the Opportunities section.
Opportunities
The Opportunities section provides recommendations for how to optimize a scene for a selected device. Use the Device dropdown to specific the device type.
Asset-level performance
Assets are critical to a scene experience. However, assets are often the cause of poor performance when properties such as polycount and material size aren’t monitored and optimized. The following parts of the Performance Panel can help analyze asset performance and identify potential risks.
Select an object in the hierarchy to get an overview of its properties and performance in the Performance Panel. Multiple objects can be selected at once to give a combined overview.
Secondary selection
It’s possible to select an object in a scene from within the Performance Panel’s right-side viewport to get more context on it.
Within the right-side viewport, click the arrow icon in the top right corner to select an object in the scene.
