We are very proud to support developers who share that vision with GPUOpen, our website for developers stocked with valuable software and tools based on open standards that they can use to help maximize the performance of their games. For example, dedicated tools like the Radeon™ GPU Profiler help accelerate development cycles and optimize games for next-gen APIs such as DirectX® 12 and Vulkan®.


There’s a lot more to share this GDC, with the following updates to our Radeon Software for Developers tools being released on GPUOpen and presented during the AMD-sponsored sessions at the conference tomorrow, Wednesday, March 20.



Radeon™ GPU Profiler 1.5

GDC 2019 Session: “AMD GPU Performance Revealed”, Room 3001, West Hall, Moscone Center
The Radeon™ GPU Profiler (RGP) is our low-level optimization tool for DirectX 12, Vulkan, and OpenCL™ that runs on Windows® and Linux® and provides detailed graphics and compute timing and occupancy information on AMD Radeon™ GPUs.



With RGP, developers can easily visualize precisely how their game or application is utilizing the GPU so they can fully optimize it for Radeon™ graphics cards, helping deliver a better experience to end-users using AMD.


At GDC we’ll be showing three new features that we are adding in the RGP 1.5 update. Instruction timing, available for all shader stages, lets you see instruction durations to find out what part of your program is “hot.” Shader ISA lets you see shader code in the pipeline state and user market display helps you better understand what the GPU is working on.


The Radeon GPU Profiler 1.5 update is coming soon with planned availability in April 2019.



Radeon™ GPU Analyzer 2.1

GDC 2019 Session: “AMD GPU Performance Revealed”, Room 3001, West Hall, Moscone Center
The Radeon™ GPU Analyzer (RGA) is our offline compiler and shader performance analysis tool for DirectX®, Vulkan, OpenGL®, and OpenCL that runs on Windows and Linux which also integrates into popular third-party developer tools like RenderDoc, Shader Playground, CodeXL, and Pyramid.



RGA improves developer efficiency by providing an integrated shader code editing, compilation, and analysis environment outside of a game engine that helps quickly validate different optimization strategies. As with the Radeon GPU Profiler, the optimizations RGA helps achieve can deliver better end-user experiences on Radeon graphics.


The updated 2.1 version of RGA being presented at GDC has a new GUI interface for Vulkan and OpenCL analysis and the ability to use the shader compiler directly from the installed Radeon Software driver – rather than the one included with the tool.


Radeon GPU Analyzer 2.1 will be available on March 20, 2019.




Microsoft® PIX AMD-specific GPU Data Support

GDC 2019 Session: “AMD GPU Performance Revealed”, Room 3001, West Hall, Moscone Center
Microsoft® PIX is the premier tool for debugging and analyzing DirectX 12 game performance on Windows® 10, and it has been updated for GDC 2019 to enable developers who primarily use PIX to debug and analyze their DX12 performance to better optimize their games for Radeon graphics.



The updated version of Microsoft PIX, 1903.12, in addition to providing AMD GPU-specific per command performance data and DirectX 12 stage wave occupancy data, now includes AMD GPU-specific high frequency counter data.


The high frequency counter data is based on AMD streaming performance metrics (SPM) which are heavily relied upon by console developers to understand the precise performance impact of overlapping command execution on the GPU.


Microsoft PIX 1903.12 is available now.




OCAT (Open Capture and Analytics Tool) 1.4

GDC 2019 Session: “AMD GPU Performance Revealed”, Room 3001, West Hall, Moscone Center

OCAT is our lightweight open source capture and performance analytics tool with support for DirectX® 11, DirectX 12, and Vulkan. It runs in parallel with your game, sampling available DXGI presentation metrics to provide an accurate view of frame timing, pacing, and delivery.



OCAT can be used by developers to help discover and fix issues in frame pacing, and by end-users for detailed benchmarking of their system’s performance in DX12 and Vulkan games.


For the OCAT 1.4 update, we’ve added an audible indicator that capturing is taking place when you don’t want to use the in-game overlay or there are compatibility issues with certain titles prevent its use. We’ve also updated the in-game overlay to include a rolling frame time graph and to display what graphics API is currently being used. Lastly, there is a bar can be added to the overlay that changes color with each frame to aid with post-process video analysis of the capture.


OCAT 1.4 will be available on March 20, 2019.




AMD Radeon FreeSync
™ 2 HDR samples

GDC 2019 Session: “A Blend of GCN Optimisation and Color Processing”, Room 3001, West Hall, Moscone Center

AMD Radeon FreeSync™ 2 HDR 1,2 technology raises the bar to the next level for gaming displays, enabling an exceptional user experience when playing HDR games, movies, and other content.



To help game developers properly set up their games to work with Radeon FreeSync 2 HDR, starting at GDC 2019 AMD is going to post a series of in-depth technical blogs along with sample code that show how to set up, activate and render with Radeon FreeSync 2 HDR enabled on AMD Radeon GPUs with the required Radeon FreeSync 2 HDR display attached.


The first blog planned is an introduction to the series and covers color spaces, with follow up blogs in the series covering tone mapping, gamut mapping, and ending with how to use the provided sample code to enable Radeon FreeSync 2 HDR in your application.
