Introduction
When building a game in Unity3D for Xbox, optimizing performance is a key element that can significantly impact the player experience. However, developers often overlook one important aspect—the choice of the appropriate graphics API. In this post, we will discuss how changing the Graphics API to DirectX 12 can improve game performance by increasing the number of available frames per second (FPS).
Why DirectX 12?
By default, games built in Unity for the Universal Windows Platform (UWP) on Xbox use the DirectX 11 API. While DX11 is stable, it has limitations that can affect performance, especially in graphically demanding games. Switching to DX12 allows developers to fully utilize GPU power and additional resources offered by the new system architecture.
Benefits of Using DirectX 12
- Access to 100% GPU Computing Power: By using DX12 in UWP applications, developers have full access to GPU computing power, allowing for better use of graphical resources and improved performance. In the case of DX11, only 50% of GPU power was accessible, which significantly limited rendering capabilities and the efficiency of games. Learn more.
- Better GPU Utilization: DX12 provides more direct access to GPU power, resulting in improved rendering performance.
How to Change the Graphics API to DirectX 12
To change the graphics API settings in Unity3D, follow these steps:
- Open Project Settings: Go to Edit > Project Settings in the Unity menu.
- Select the Xbox Platform: In the Player tab, choose the Xbox Universal Windows Platform (UWP).
- Uncheck Auto Graphics API: Disable the Auto Graphics API option to allow for manual configuration of the graphics settings.
- Set Graphics API to DirectX 12:In the Other Settings section, locate the Graphics APIs option, remove DirectX 11 from the list, and then add DirectX 12 as the primary graphics API.
- Save Changes:Ensure all changes are saved and test the game on your Xbox device.
Conclusion
Changing the Graphics API to DirectX 12 in games built in Unity for the Xbox platform is a simple yet effective way to increase performance and frame rates. Optimizing performance is a crucial element in ensuring a positive player experience, so it’s worth taking the time to adjust these settings.
With access to 100% of the GPU’s computing power, developers can fully utilize the capabilities of Xbox consoles, opening up new possibilities in game development. We encourage you to try out these tips and discover how they can improve your game’s performance on the Xbox platform.
