# 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="/files/pJzAhXFMLmpWvOZX3k5e" alt="" data-size="line"> to calculate scene size and estimated project loading time
* **Performance** – Click the icon <img src="/files/MVlWMRrJ6q51KGEtMfdN" alt="" data-size="line"> to measure FPS (based on your device) and identify performance-impacting factors

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://help.vectary.com/documentation/sharing-exporting-embedding/performance-analyzer.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
