Getting started with Radeon™ Memory Visualizer (RMV)
Radeon™ Memory Visualizer (RMV) is a tool provided by AMD for use by game engine developers. It allows engineers to examine, diagnose, and understand the GPU memory management within their projects.
Using AMD FreeSync™ Premium Pro HDR: Code Samples
Part 4 of a series of posts on AMD FreeSync™ Premium Pro Technology. Here, we look at how to enable FreeSync Premium Pro with all next gen graphics APIs.
Using the Visual Studio® Code Extension for RGA
This is a Visual Studio® Code extension for the Radeon GPU Analyzer (RGA). This extension makes it possible to use RGA directly from within VS Code.
Integrating FidelityFX into the Ego Engine
Tom Hammersley from Codemasters talks about integrating FidelityFX into the Ego Engine and implementing Contrast Adaptive Sharpening (CAS).
Using Radeon™ GPU Analyzer with DirectX®12 Graphics

Understanding concurrency (and what breaks it) is extremely important when optimizing for modern GPUs.
Anatomy Of The Total War Engine: Part V
The final instalment in Tamas Rabel’s insight into developing the Total War engine looks at Multi-GPU.
Anatomy Of The Total War Engine: Part IV
Tamas Rabel talks about how Total War: Warhammer utilized asynchronous compute to extract some extra GPU performance in DirectX® 12 and delves into the process of moving some of the passes in the engine to asynchronous compute pipelines.
Anatomy Of The Total War Engine: Part III
Here’s Tamas Rabel again with some juicy details about how Creative Assembly brought Total War to DirectX® 12.
Anatomy Of The Total War Engine: Part II
Tamas Rabel from Creative Assembly discusses how performance was measured with the Total War Engine.
Anatomy Of The Total War Engine: Part I
Tamas Rabel, Lead Graphics Programmer on the Total War series provides a detailed look at the Total War renderer as well as digging deep into some of the optimizations that the team at Creative Assembly did for the brilliant, Total War: Warhammer.
GCN Shader Extensions for Direct3D and Vulkan
One of the mandates of GPUOpen is to give developers better access to the hardware, and this post details extensions for Vulkan and Direct3D12 that expose additional GCN features to developers.
Maxing out GPU usage in nBodyGravity
Asynchronous compute can help you to get the maximum GPU usage. I’ll be explaining the details based on the nBodyGravity sample from Microsoft.
