GPUOpen May 2020 relaunch blog banner_blk.jpg

Last week, we were very proud to be part of the Microsoft® Game Stack Live 2021 virtual developer conference where we made some important announcements and gave two talks for developers. To support our GSL releases, we posted some updates to GPUOpen but we’re not done yet and today we have some more exciting new releases and updates for developers to tell you about.


Game Stack Live News Recap

Our biggest announcement made last week as part of the GSL graphics keynote was that select AMD FidelityFX effects are now available for the Xbox Series X|S in the latest Game Development Kit (GDK). We also committed our support for Microsoft’s updates about how they are continuing to evolve DirectX® with the Microsoft DirectX® 12 Agility SDK and HLSL Shader Model 6.6 and released an AMD Radeon™ Software Adrenalin developer driver for these updates. You can watch the AMD part of the keynote presentation below.

Along with the news from the keynote, we held two technical talks for developers which you can now watch on the Game Stack Live YouTube channel, “Denoising Raytraced Soft Shadows on Xbox Series X|S and Windows with FidelityFX” and “AMD Ryzen™ Processor Software Optimization”. Finally, to support these talks, we released an update to our FidelityFX Denoiser and published the brand-new AMD Ryzen™ Performance Guide.

More GPUOpen Updates for Developers

This week, we have some exciting effects-related releases for developers on GPUOpen which build upon our announcements made at the GSL event.

  • Hybrid Shadows: This brand-new sample code shows off a way to use ray tracing and traditional rasterization to accelerate high-quality shadows, and uses our FidelityFX shadow denoising system developed specifically for this technique.

  • Radeon™ Cauldron v1.4: We’ve updated Radeon Cauldron – our mini-engine and renderer that hosts our effects samples – with a bunch of new features too. These include a wireframe mode, a new lighting/shadow import pipeline, and much more.

  • AMD FidelityFX Ambient Occlusion: Combined Adaptive Compute Ambient Occlusion (CACAO), our AMD RDNA™ architecture-optimized implementation of ambient occlusion, has been updated with optimized native resolution SSAO.

  • AMD FidelityFX HDR Mapper: Our open-source Luminance Preserving Mapper (LPM) library that lets developers easily integrate HDR into games has been updated with windowed mode HDR10 support for DirectX®12.

  • AMD FidelityFX Parallel Sort: Our latest FidelityFX effect, Parallel Sort, is an AMD RDNA™ architecture-optimized version of the Radix Sort algorithm and has been updated with support for Vulkan®.

The Radeon™ GPU Profiler (RGP) is our ground-breaking low-level optimization tool that provides detailed information on Radeon graphics cards and we recently updated it to v1.10 with support for Vulkan® ray tracing and added GPU cache counters. Now you can learn more about our latest updates to RGP in the video below presented by one of our senior tools engineers, Gordon Selley.
