As expected, Microsoft has unveiled new details about their upcoming new DirectX 12 version at this month’s Game Developers Conference in San Francisco.
DirectX 12 introduces the next version of Direct3D, the graphics API at the heart of DirectX and a critical part of a game or game engine.
Enhanced Performance and Efficiency
Microsoft has redesigned Direct3D to be faster and more efficient than previous releases, making it suitable for richer scenes and providing it with the power to handle more objects and fully utilize modern GPU hardware. This redesign is particularly significant for game developers who are constantly pushing the boundaries of visual fidelity and performance. Microsoft explains:
“What makes Direct3D 12 better? First and foremost, it provides a lower level of hardware abstraction than ever before, allowing games to significantly improve multithread scaling and CPU utilization. In addition, games will benefit from reduced GPU overhead via features such as descriptor tables and concise pipeline state objects.”
This means that DirectX 12 can better distribute the workload across multiple CPU cores, which is crucial for modern gaming experiences that demand high performance. By reducing the overhead on the GPU, DirectX 12 ensures that more of the GPU’s power is dedicated to rendering complex scenes and effects, rather than managing resources.
New Rendering Pipeline Features
Direct3D 12 also introduces a set of new rendering pipeline features that will dramatically improve the efficiency of algorithms such as order-independent transparency, collision detection, and geometry culling. These features are essential for creating realistic and immersive game worlds. For example, order-independent transparency allows for more accurate rendering of transparent objects, which is crucial for effects like glass, water, and smoke.
“And that’s not all – Direct3D 12 also introduces a set of new rendering pipeline features that will dramatically improve the efficiency of algorithms such as order-independent transparency, collision detection, and geometry culling.”
Collision detection is another critical aspect of game development, as it determines how objects interact with each other within the game world. With DirectX 12, collision detection algorithms can run more efficiently, allowing for more complex interactions and more dynamic environments. Geometry culling, on the other hand, helps to optimize rendering by only drawing objects that are visible to the player, thereby saving valuable processing power.
Broader Hardware Compatibility
One of the standout features of DirectX 12 is its broader hardware compatibility. Unlike previous versions, DirectX 12 is designed to work across a wide range of devices, from high-end gaming PCs to tablets and smartphones. This means that developers can create games that scale across different hardware configurations, providing a more consistent experience for players regardless of their device.
Developer Tools and Support
Microsoft is also providing a suite of developer tools and support to help game developers make the most of DirectX 12. These tools include debugging and performance analysis tools that can help developers identify and fix performance bottlenecks in their games. Additionally, Microsoft is offering extensive documentation and sample code to help developers get started with DirectX 12.
