Microsoft unveils major DirectX ray tracing upgrades that boost performance without new hardware, promising better lighting and reflections in future games.
Microsoft advances ray tracing in DirectX
Microsoft has introduced a major update to its DirectX technology, which is used for rendering graphics in video games and other applications. This update brings significant improvements to ray tracing, a technique that creates more realistic lighting, shadows, and reflections, without needing new graphics card hardware.New technologies reduce resource demands
The update includes two key technologies: Clustered Geometry and PTLAS. Clustered Geometry allows game scenes to be broken into smaller, reusable parts, reducing the need to constantly recalculate entire structures. PTLAS applies a similar approach to animated scenes, updating only the parts that change, which helps save processing power.Performance gains shown in tests
In a technical test using an experimental version of DirectX 12 Agility SDK, performance improved dramatically. On a Radeon RX 9070, the frame rate increased from 1.2 to 79 frames per second in a test scene. The time to build acceleration structures dropped from 788 milliseconds to 3.11 milliseconds, and memory usage fell by almost 90 percent.Support for existing hardware
These advancements are compatible with existing graphics cards, including NVIDIA GeForce RTX, AMD Radeon RX 9000, and Intel Arc series B GPUs, as well as some integrated GPUs. However, they require updated drivers and integration by game developers. Players may not see immediate improvements in existing games, but future titles could benefit from these tools.Future potential depends on implementation
Microsoft's updates aim to make ray tracing more efficient and accessible, but the actual impact on players will depend on how game studios use these technologies. While the improvements are promising, real-world performance gains will vary based on how developers implement the new features in their games.
