# Optimizing Your Project for Higher FPS
|
||||
|
||||
Enhancing the performance and framerate of Unreal Engine VR applications, whether running standalone or streaming from a PC, can sometimes be challenging depending on the nature of your project. This guide will walk you through generic strategies that can significantly boost your project's performance and framerate with minimal effort.
|
||||
|
||||
## Meta Quest Link Advanced Graphics Preferences
|
||||
|
||||
When streaming from a PC to Meta Quest devices, the default refresh rate is set at `72 Hz`. However, you can increase this to `120 Hz`, which not only enhances the refresh rate but also reduces the rendering resolution, potentially improving performance. Follow these steps to make the adjustment:
|
||||
|
||||
1. Open the Meta Quest Link app and navigate to the `Devices` tab.
|
||||
|
||||
|
||||
|
||||
2. Choose the device for which you would like to tweak the refresh rate.
|
||||
|
||||
|
||||
|
||||
3. In the device settings, scroll down to the `Advanced` section and select `Graphics Preferences`.
|
||||
|
||||
|
||||
|
||||
4. Choose your desired refresh rate. In this case select a refresh rate of `120 Hz`. After making your selection, click `OK`, and the Meta Quest Link app will restart to apply the changes.
|
||||
|
||||
|
||||
|
||||
5. Once the Meta Quest Link app restarts, go back to the `Devices` tab, select your device, and confirm the refresh rate setting under `Advanced > Graphics Preferences`.
|
||||
|
||||
|
||||
|
||||
6. Now, open your Unreal Engine project and navigate to `Project Settings`. Under `Engine > General Settings > Framerate`, you can fine-tune and experiment with the framerate settings to match your project's requirements.
|
||||
|
||||
|
||||
|
||||
## Game User Settings and Engine Scalability Settings
|
||||
|
||||
Unreal Engine offers predefined graphics quality profiles known as Engine Scalability Settings, which can be easily adjusted to optimize performance. These settings can be modified directly within the Unreal Editor through the Settings menu on the toolbar or dynamically at runtime using code. Importantly, these settings are universal, meaning changes made in the Unreal Editor will apply to the game when run in PIE (Play In Editor) mode, and settings adjusted via code will also affect the editor itself.
|
||||
|
||||
|
||||
|
||||
> [!NOTE]
|
||||
> The SenseGlove Unreal Engine Plugin includes specialized
|
||||
> [console commands](../../misc/console-commands/) that allow you to switch
|
||||
> between different Engine Scalability Settings on the fly. Please note that
|
||||
> these commands require you to set up
|
||||
> [SGGameInstance](../../getting-started/setup-senseglove-default-classes/sggameinstance.md)
|
||||
> and
|
||||
> [`SGGameUserSettings`](../../getting-started/setup-senseglove-default-classes/sggameusersettings.md).
|
||||
|
||||
In order to switch between various Engine Scalability Settings, you can use the `Get Game User Settings` Blueprint function and then cast it to `SGGameInstance`.
|
||||
|
||||
|
||||
|
||||
> [!IMPORTANT]
|
||||
> Unreal Engine's default Blueprint functions only allow you to set Engine
|
||||
> Scalability Settings to `Low` or `Epic`. To access the full range of settings,
|
||||
> `SGGameUserSettings` extends Blueprint access to all Engine Scalability
|
||||
> Settings and includes hardware benchmarking to detect the optimal settings.
|
||||
> Therefore, it's essential to make
|
||||
> [`SGGameUserSettings`](../../getting-started/setup-senseglove-default-classes/sggameusersettings.md)
|
||||
> or a subclass of it the default Game User Settings class to utilize all these
|
||||
> features.
|
||||
|
||||
The following Blueprint code from the [SGBasicDemo-OpenXR](https://dev.azure.com/SenseGlove/_git/SenseGlove-Unreal-SGBasicDemo-OpenXR) example scene demonstrates how to bind numeric keys `1` to `5` to set various Engine Scalability Settings, and key `0` to utilize hardware benchmarking to determine the optimal Engine Scalability Settings:
|
||||
|
||||
- `0`: Use hardware-benchmarking to determine the optimal Engine Scalability Settings.
|
||||
- `1`: Set Engine Scalability Settings to `Low`.
|
||||
- `2`: Set Engine Scalability Settings to `Medium`.
|
||||
- `3`: Set Engine Scalability Settings to `High`.
|
||||
- `4`: Set Engine Scalability Settings to `Epic`.
|
||||
- `5`: Set Engine Scalability Settings to `Cinematic`.
