DirectX 11.2 is a set of application programming interfaces (APIs) developed by Microsoft that enhances the performance and visual quality of games and multimedia applications on Windows platforms. It provides developers with tools to create more realistic graphics and improved gameplay experiences by leveraging advanced hardware features. One of the key improvements in DirectX 11.2 is support for tiled resources, which allows games to load only the necessary textures and assets, optimizing memory usage. Additionally, it introduces features like dynamic multithreading and improved support for Windows Store apps, making it easier for developers to create high-quality applications for both PCs and tablets.
