Or do graphics cards have free compute shaders that can run decompression to load assets while gaming?

Several factors affect game performance when it comes to compression/decompression. Here’s a breakdown of what works and what’s recommended: At the same time, recent advances in I/O technology have dramatically improved available I/O bandwidth on the end user system. It’s typical to see a consumer system equipped with a PCIe Gen3 or Gen4 NVMe device, capable of delivering up to 7 GB/s of data bandwidth. Also, 64 KB happens to be the standard tile size for tiled or sparse resources in graphics APIs (DirectX and Vulkan), which makes GDeflate compatible with future on-demand streaming architectures leveraging these API features.

What Is a Decompression Game?

With GPU-accelerated GDeflate decompression, the system can deliver effective bandwidth well in excess of what’s possible without applying compression. It is effectively multiplying data throughput by its compression ratio. The CPU remains fully available for performing other important tasks, maximizing system-level performance.

The minimum requirements start off with an older-generation Core i3 or Ryzen 3 CPU and a GTX 960 or RX 470 to play the game at 720P with very low settings. Jumping up to 1080P medium settings, the requirements shift to an i5-8400/Ryzen 5 3600 and an RTX 2060/RX-5700. For 1440P high, an RTX 3060 Ti/RX 6800 is required plus a Core i5-11400/or Ryzen 5 5600. Next-generation game engines require streaming huge amounts of data, aiming to create increasingly realistic, detailed game worlds. Given that, it’s necessary to rethink game engines’ resource streaming architecture, and fully leverage improvements in I/O technology. 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.For ray-traced 1440p gameplay at high settings, the demands shift another notch up to an RTX 3070/RX 6800 XT and an i5-11600K/Ryzen 5 5600X. Then for users who want to crank all the visuals to the max at 4K resolution, the system requirements jump up to an RTX 4080/RX 7900 XTX and a Core i7-12700K/Ryzen 9 5900X. Whilst this work was developed for sports and athletes who have been in Tokyo for the Olympics and Paralympics, the decompression process will also be rolled out to staff at the UKSI. Rolling this decompression work out across the EIS will allow everyone to process the Olympic and Paralympic Games, something our staff have worked towards and contributed to during this unique cycle, whilst tying into our values of We Care and We Collaborate.

DirectStorage 1.1 doesn’t have a way to force CPU decompression on a per-request or per-queue basis. Instead, custom decompression can be used. For example, a title might designate DSTORAGE_CUSTOM_COMPRESSION_0 to mean “CPU decompressed GDeflate” and then use the custom decompression queue to decompress on the CPU. In general, various data types, such as texture and geometry, compress at different ratios. This can cause some variation in GPU decompression execution performance.

The next stage is Process the Emotion, which focuses on making sense of the emotion that surrounds performance and is split into six phases. This stage will celebrate the positive and explore what was challenging. It will also highlight strengths and skills which can be utilised in the next steps.
