Enhanced Control Over Graphics
One standout feature of DX12 is its provision for more control over graphic details. While DX11 manages most of the graphic hardware resources, DX12 lets developers have direct control thereby allowing them to optimize the game design based on the target GPU architecture. For example, developers, given the DX12’s facilities, could fine-tune operations such as state transitions or synchronization for Nvidia’s architecture, offering an aligned graphical performance.
Performance Improvements and CPU Usage
DX12 brings sizable performance improvements and better CPU usage. Its design exhibits an ability to handle multiple CPU cores simultaneously without major bottlenecks. Unlike DX11, which struggles when asked to work across multiple cores, DX12 efficiently distributes the workload among them. For example, in a game relying heavily on CPU (like the latest real-time strategy games), you might notice considerable improvements with DX12.
Also, DX12 features an exciting innovation called ‘draw bundles’. These pre-packaged sets of graphical instructions provide a remarkable saving in CPU utilization, proving fantastic for recurring motifs in your gameplay. ResourceManager is another feature DX12 introduces, providing more efficient handling and streaming of game assets.
Differences Between DX11 and DX12
