# Performance analyzer

## Overview

Optimizing a project is essential for maintaining good performance. The **Preview mode** provides insights into how optimized the scene is and offers tools for quick improvements:

* Total number of objects, source geometries, and polygons
* Number of textures and their resolution (resolution can be changed directly here)
* Number of interactions and animations (unused ones can be removed instantly)
* Project loading time and total size
* Performance metrics such as FPS and factors that affect it

## Optimization Indicators

* <mark style="color:red;">R</mark><mark style="color:red;">**ed warning icon**</mark> indicates a metric that needs optimization. It's always a good idea to keep values low where possible.
* <mark style="color:green;">G</mark><mark style="color:green;">**reen check icon**</mark> means the value is acceptable, but it doesn't always guarantee good performance/loading time. For example, having many `2048×2048` textures can still negatively impact loading time and should ideally be optimized (either reduced to the lowest practical resolution or removed entirely if it doesn't provide significant visual improvement).

## Metric Descriptions

* **Total objects** – Total number of objects in the project (including hidden ones)
* **Source Geometries** – Number of objects with unique geometry
* **Polygons** – Total polygon count in the project<br>
* **Textures** – Number of textures currently in use (unused textures are not listed)
  * Texture resolution can be changed directly here<br>
* **Interactions** – "Unreferenced" interactions are linked to deleted objects. Click `Clear unreferenced interactions` to remove them
* **Animations** – Displays animation tracks with no keyframes. Use `Clear empty animations` to delete them<br>
* **Loading time** – Click the icon <img src="https://2973737105-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FAXNLyKVZ2tvtyDr8sVES%2Fuploads%2F3hDmeMUEMHQCRXewe5uU%2Fimage.png?alt=media&#x26;token=6bc4acc1-8cc9-4ed9-be5b-037242afaa72" alt="" data-size="line"> to calculate scene size and estimated project loading time
