Adjust the settings to customize how the Profiler collects and displays data.

| **Setting**                                      | **Description**                                                                                                                                                                                                                                                                                                                                                                                                         |
| ------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Profiler Capture Storage Path**                | Set the default folder where Unity saves [Profiler captures](/engine/6000.7/manual/analysis/profiler/window.md#captures-list).                                                                                                                                                                                                                                                                                          |
| **Frame count**                                  | Set the maximum number of frames for the Profiler to capture. You can set this number between 600 and 4,000.Higher number of loaded frames increases memory usage of Unity Editor.                                                                                                                                                                                                                                      |
| **Automatic memory management**                  | Automatically manage Profiler memory usage. When the system memory usage is at a critical level and the Profiler uses more than 75% of the Editor memory, Unity discards data until the system memory usage is back to a normal state, or the Profiler uses less than 25% of Editor memory.                                                                                                                             |
| **Show stats for 'current frame'**               | Set whether to display annotations on the frame line when you select the Current Frame button (⏭) on the Profiler controls.This setting is disabled by default, because the annotations might make it difficult to view data in real-time. To display the annotations, enable this setting.                                                                                                                             |
| **Default recording state**                      | Select which recording state the Profiler opens in:**Enabled**: Keeps the Record button enabled between profiling sessions.**Disabled**: Disables the Record button, regardless of whether you turn it on or off during your profiling session.**Remember**: Remembers whether you enabled or disabled the Record button during your session and keeps it at its last state the next time you open the Profiler window. |
| **Default Editor target mode on start**          | Select what mode the Target Selection dropdown targets by default:**Play mode** (default): Targets [Play mode profiling](/engine/6000.7/manual/analysis/profiler/profiling-applications/profiling-play-mode.md) by default.**Edit mode**: Targets [Edit mode profiling](/engine/6000.7/manual/analysis/profiler/profiling-applications/profiling-edit-mode.md) by default.                                              |
| **Custom connection ID**                         | Change the name of your application as it appears in the Target Selection dropdown.                                                                                                                                                                                                                                                                                                                                     |
| **Target Frames Per Second (Highlights Module)** | Set the target frames per second that the [Highlights Profiler module](/engine/6000.7/manual/analysis/profiler/visualizing-data/highlights.md) uses. The Highlights Profiler module flags any frames which exceed this target frame rate.                                                                                                                                                                               |
