Second, the bitstream within tiles is specifically formatted to expose finer-grained, SIMD-level parallelism. We expect that a cooperative group of threads will process individual tiles, as the group can directly parse the GDeflate bitstream using hardware-accelerated data-parallel operations, commonly available on most SIMD architectures.

However, a note I would say is in previous games, any semblance of warping or shifting instantly was likely because that part of the level exists, it's just in a place you would never normally get to. Source engine games for instance have a maximum map size of about 2048 feet in all directions (although this somewhat misleading, since the map size is 32,768 units in each direction and the defacto scale is 16 units = 1 foot). You can fit a lot of stuff in that volume. The Xbox Velocity Architecture was designed as the ultimate solution for game asset streaming in the next generation. This radical reinvention of the traditional I/O subsystem directly influenced all aspects of the Xbox Series X design. If our custom designed processor is at the heart of the Xbox Series X, the Xbox Velocity Architecture is the soul. Through a deep integration of hardware and software innovation, the Xbox Velocity Architecture will power next-gen gaming experiences unlike anything you have seen before.

In summary

Experiencing a range of emotions before, during and after the Games is completely normal and in a bid to help athletes and support staff to positively process the emotional experience of the Tokyo 2020 Games, the UK Sports Institute’s (UKSI) Psychology team will be working closely with sports on a post-Games period of Performance Decompression. This applies to those who have attended the Games, and those providing remote support whether technical or operational. We have all been in this together. Make sure to change the default staging buffer size whenever GPU decompression is used. The current 32 MB default isn’t sufficient to saturate modern GPU capabilities. This is an early preview of the sample; performance numbers vary with different workloads/hardware.

When we set out to design the Xbox Series X, we aspired to build our most powerful console ever powered by next generation innovation and delivering consistent, sustained performance never before seen in a console with no compromises. To achieve this goal, we knew we needed to analyze each component of the system, to push beyond the limitations in traditional console performance and design. It was critical in the design of the Xbox Series X to ensure we had a superior balance of power, speed and performance while ensuring no component would constrain the creative ambition of the world’s best creators, empowering them to deliver truly transformative next gen gaming experiences not possible in prior console generations. If a game wishes to have more control over exactly how CPU decompression is performed – integrating with its own job system perhaps, then DSTORAGE_DISABLE_BUILTIN_CPU_DECOMPRESSION, can be specified for NumBuiltInCpuDecompressThreads. When configured in this way, DirectStorage will no longer perform CPU decompression itself. Instead, the title can use the custom decompression queue with the DSTORAGE_GET_REQUEST_FLAG_SELECT_BUILTIN flag to collect decompression work. The game can use the same codec mentioned above to decompress the data, or it can plug in its own GDeflate decompression implementation if it wishes. Forcing CPU DecompressionDirectStorage 1.0 improves the data transfer part of this process. Advances in Windows 11 combined with DirectStorage allow developers to make use of the higher bandwidth of NVMe drives. DirectStorage enabled games installed on NVMe drives should expect to see reductions in load times by up to 40%. After enhancing this part of the pipeline, developers will want to improve decompression performance next.
