Xbox Velocity Architecture
The Xbox Velocity Architecture is the new architecture we’ve created for the Xbox Series X and Xbox Series S to unlock new capabilities never-before seen in console development.
It consists of four components: our custom NVMe SSD, a dedicated hardware decompression block, the all new DirectStorage API, and Sampler Feedback Streaming (SFS). This combination of custom hardware and deep software integration allows developers to radically improve asset streaming and effectively multiply available memory.
It will enable richer and more dynamic living worlds unlike anything ever seen before. It also effectively eliminates loading times, and makes fast travel systems just that: fast.
