Due to the nature of this scheme, there’s a tail-effect where, as the batch runs out of tiles to decompress, the GPU starts to have less work to do. For this reason, the larger the batch, the smaller the tail effect. The size of each batch is affected by the speed of the IO device and the size of the staging buffer. Generally, the larger the staging buffer, the larger each batch can be.
Set aside some R&D time after the release for understanding and experimenting with GPU decompression. RichardtST said:Y'all are just slow and need to learn how to code. DangerZone has been doing instant dimension changes for years. In java. On spinny drives. On Intel Core 2 duo. With integrated graphics. When properly applied, the KISS PRINCIPLE (along with a heaping helping of cleverness) can do absolute wonders.Assuming you're talking about this DangerZone (https://www.orespawn.com/), then this comparison is just silly. In preparation for DirectStorage integration, applications should group resource I/O and creation requests close together in time. Ideally, resource I/O and creation operations occur in their own CPU thread, separate from threads doing other loading screen activities like shader creation. A many-core SIMD machine consumes the GDeflate bitstream by design, explicitly exposing parallelism at two levels. NVIDIA: https://developer.nvidia.com/blog/accelerating-load-times-for-directx-games-and-apps-with-gdeflate-for-directstorage/Due to the additional graphics features added to the PC port, on top of the game's already great visuals, the game's system requirements are quite beefy. The game requires up to a RTX 4080 if you want to max out the game's visuals at 4K.
Hardware vendors may begin releasing drivers for DirectStorage 1.1 in the weeks before our release. Drivers from our key partners ensure that developers will see the full potential of GPU decompression. “DirectStorage 1.1 with GPU decompression will enable developers to unleash their creativity, delivering more detailed and visually stunning worlds,” said Scott Herkelman, senior vice president and general manager, Graphics Business Unit at AMD. “We have worked closely with Microsoft to ensure the best possible experience on AMD devices and platforms.”GDeflate provides a new GPU decompression format that all hardware vendors can support and optimize for. Microsoft is working with key partners like AMD, Intel, and NVIDIA to provide drivers tailored for this format. “Intel is excited to release drivers co-engineered with Microsoft to work seamlessly with the DirectStorage Runtime to bring optimized GPU decompression capabilities to game developers!” said Murali Ramadoss, Intel Fellow and GM of GPU Software Architecture. Like all DirectX technologies, with DirectStorage, Microsoft is working to ensure that gamers have great options for compatibility and performance for their hardware. NVIDIA RTX IO is now included in the current Game Ready Driver (version 526.47), which offers accelerated decompression throughput. This is an early preview of the sample; performance numbers vary with different workloads/hardware. Modern games require a significant amount of data to create the realistic worlds and universes that gamers experience. To enable the processor to work at its optimum performance, all of this data must be loaded from storage into memory. The explosion of massive, dynamic open-world environments and living, persistent worlds with increased density and variety has only increased the amount of data required. From environmental mesh data, high polygon character models, high resolution textures, animation data, audio and video source files and more all combine together to deliver the most immersive game play environment for the player. Custom NVME SSD: The foundation of the Xbox Velocity Architecture is our custom, 1TB NVME SSD, delivering 2.4 GB/s of raw I/O throughput, more than 40x the throughput of Xbox One. Traditional SSDs used in PCs often reduce performance as thermals increase or while performing drive maintenance. The custom NVME SSD in Xbox Series X is designed for consistent, sustained performance as opposed to peak performance. Developers have a guaranteed level of I/O performance at all times and they can reliably design and optimize their games removing the barriers and constraints they have to work around today. This same level of consistent, sustained performance also applies to the Seagate Expandable Storage Card ensuring you have the exact same gameplay experience regardless of where the game resides.
What we need is a GPU-friendly data compression approach that can scale performance as GPUs become wider and more parallel.

With Moore’s law ending, we can no longer expect to get “free” performance improvements from serial processors.
Great Deal
