# Adaptive Performance provider settings reference > Explore the settings available for Adaptive Performance providers. Explore the settings available for Adaptive Performance providers. Each [Adaptive Performance provider](/engine/6000.5/manual/analysis/runtime-performance-scaling/adaptive-performance/get-started/providers.md) supplies several settings for controlling behavior at runtime and during development. The following settings are available for all providers unless otherwise specified. Values are provider-specific, meaning the actual impact of the value depends on the provider you're using. Access these settings at **Edit** > Editor > **Adaptive Performance**. **Adaptive Performance provider settings in the Project Settings window.:** ![](/api/media?file=/engine/6000.5/media/images/ap-provider-settings.png) ## Runtime Settings The **Runtime Settings** section contains the following settings: | **Property** | **Description** | | ------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Auto Performance Mode** | Automatically adjusts CPU and GPU levels to balance performance and battery life. This setting is available only for the Simulator. | | **Boost mode on startup** | Boosts CPU and GPU performance at application startup before anything loads. Learn more about [temporary performance boosts](/engine/6000.5/manual/analysis/runtime-performance-scaling/adaptive-performance/performance-optimization-strategies/temporary-performance-boosts/boosts.md). This setting is available only for the Simulator. | ### Indexer Settings The Indexer monitors the device's thermal and performance state to decide when to adjust quality levels using [scalers](/engine/6000.5/manual/analysis/runtime-performance-scaling/adaptive-performance/performance-metrics/scalers.md). The **Indexer Settings** section contains the following settings: | **Property** | **Description** | | ---------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Active** | Enables the Indexer system. | | **Thermal Action Delay** | Sets the delay in seconds after any scaler is applied or unapplied because of thermal state. This option isn't available for the [Basic provider](/engine/6000.5/manual/analysis/runtime-performance-scaling/adaptive-performance/get-started/providers/basic-provider.md). | | **Performance Action Delay** | Sets the delay in seconds after any scaler is applied or unapplied because of performance state. | ### Scaler Profiles Every scaler shares a group of settings that determine the scaler's impact on performance. The Indexer prioritizes scalers with a higher impact, adjusting their levels more frequently to change the application's quality. Adaptive Performance calculates this impact score at runtime using the scaler's pre-configured settings and the current device bottleneck. The **Scaler Profiles** section contains the active [scaler profiles](/engine/6000.5/manual/analysis/runtime-performance-scaling/adaptive-performance/performance-metrics/scalers/introduction.md#scaler-profiles). Each individual scaler has the following settings: | **Property** | **Description** | | ----------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Enabled** | Enables or disables the scaler. You can change this setting during runtime. | | **Min Scale** | Defines the minimum scale of the scaler. If the minimum scale is 0.5, the minimum quality is 50% of the original value. | | **Max Scale** | Defines the maximum scale of the scaler. If the maximum scale is 1.5, the maximum quality is 150% of the original value. Often, the maximum scale is set to 1, which is then used as the default for a high-end device. | | **Max Level** | Defines the number of discrete quality levels between the minimum and maximum scale. A maximum level of 20 means that a scaler has 20 levels available between maximum and minimum quality. A binary scaler has a maximum level of 1. | | **Visual Impact** | Describes how noticeable the quality change from this scaler is to the player (**Low**, **Medium**, or **High**). Adaptive Performance prioritizes reducing scalers with low visual impact first. | | **Target** | Identifies which performance bottleneck this scaler addresses. This read-only setting helps the system apply the most effective scaler when it detects a bottleneck.**CPU**: The bottleneck is CPU.**GPU**: The bottleneck is the GPU.**Fillrate**: The bottleneck is the target frame rate. | #### Add New Scaler Profile Add or remove scaler profiles to quickly move between different performance configurations. To create scaler profiles and load different profiles at runtime, refer to [Use scaler profiles](/engine/6000.5/manual/analysis/runtime-performance-scaling/adaptive-performance/performance-metrics/scalers/scaler-profiles.md). ## Development Settings You can only use these settings in development builds. Release builds automatically disable them. The **Development Settings** section contains the following settings: | **Property** | **Description** | | --------------------- | ----------------------------------------------------------------------- | | **Logging** | Lets the Adaptive Performance subsystem log messages to the player log. | | **Logging Frequency** | Sets how frequently the system logs messages. Specified in frames. | ## Additional resources * [Set up Adaptive Performance](/engine/6000.5/manual/analysis/runtime-performance-scaling/adaptive-performance/get-started/initial-setup.md) * [Scalers](/engine/6000.5/manual/analysis/runtime-performance-scaling/adaptive-performance/performance-metrics/scalers.md) * [Providers](/engine/6000.5/manual/analysis/runtime-performance-scaling/adaptive-performance/get-started/providers.md)
