Achieve amazing visuals and performance on next-gen Windows and Xbox graphics hardware with the latest DirectX Tools and features.
New consoles and graphics cards usher in a new wave of more immersive video games. In this session, we will cover the latest innovations to our graphics platform, making it easier for game developers to push the limits of graphics on both PC and Xbox with DirectX, HLSL, PIX, HDR, and more.
The DirectX team has been working on a way to change the game for developers who want to be on the bleeding edge of graphics. We're finally ready to show the world how we're pushing the envelope with an exciting new update.
Introducing HLSL Shader Model 6.6: granting shader developers increased flexibility to enhance and expand existing rendering approaches and devise all new ones!
High Dynamic Range (HDR) is part of the gold standard for the newest generation of graphically rich games. In this talk, you'll learn about our ongoing work to improve DirectX's HDR support on PCs. We are helping to solve the problem of HDR display ecosystem variability, providing best practices for optimizing your native HDR implementations for displays, and working on exciting new technology to extend the reach of HDR PC gaming.
This talk will discuss the usage of Variable Rate Shading in Gears 5 and Gears Tactics. Our implementation targets zero perceptual drop in visual quality, works seamlessly with dynamic resolution, and runs across Xbox Series X|S and PC. Performance improvements will be discussed as well as how VRS was tuned to work across different rendering passes. We will also discuss some challenges and integration tips that can be applied to any game engine.
With raytraced visuals bumping rendering quality even higher than ever before, a significant amount of fine tuning is required to maintain real-time performance. A typical way to achieve this is to trace fewer rays, and to make sense of the noisier output that method delivers. This presentation will explain how the AMD FidelityFX Denoiser allows for high-quality raytracing results without increasing rays per pixel, and deep dives into specific RDNA2-based optimizations that benefit both Xbox Series X|S and PC.
This talk is aimed at graphics engineers that have little or no experience with ray tracing. It serves as a gentle introduction to many topics, including "What is ray tracing?", "How many rays do you need to make an image?", "The importance of [importance] sampling. (And more importantly, what is importance sampling?)", "Denoising", "The problem with small bright things". Along the way, you will learn about specific implementation details from Minecraft.
How the addition of a path traced rendering mode in Minecraft inspired our creative team. We will do a brief review of "original" Minecraft, and it's pixel art roots. We reflect on the game's unique look, and how players and creators can tell new and different stories in path traced Minecraft. Then we will discuss how this new rendering option is made available to our creators community via our texture pack system and then show the results, and speak to the aesthetic benefits and challenges of the new tech.
RTXDXI offers realistic lighting of dynamic scenes that require computing shadows from millions of area lights. Until now, this has not been possible in video games. Traditionally, game developers have baked most lighting and supported a small number of "hero" lights that are computed at runtime. This talk gives an overview of RTXDI and offers a deep dive into previously undisclosed details that enable high performance.
System & Tools
Learn how to take advantage of features on Windows and Xbox Series Consoles for improving development, performance, load times, engine integration and more.
The new Xbox Velocity Architecture in the Xbox Series X|S consoles enables developers to re-imagine how to build their games. By combining a super-fast SSD, hardware decompression, and the new DirectStorage functionality, game developers have tools to develop immersive experiences with a minimal load time for users. This session will review the benefits of the Velocity Architecture and show a real-world example.
Microsoft is excited to bring DirectStorage, an API in the DirectX family originally designed for the Velocity Architecture to Windows PCs! DirectStorage will bring best-in-class IO tech to both PC and console just as DirectX 12 Ultimate does with rendering tech. With a DirectStorage capable PC and a DirectStorage enabled game, you can look forward to vastly reduced load times and virtual worlds that are more expansive and detailed than ever. In this session, we will be discussing the details of this technology will help you build your next-generation PC games.
PIX is the essential performance tuning and debugging tool for DirectX 12 applications on Xbox and Windows. As the game industry pushes the boundaries of what is possible on the latest generation hardware, we are building the tools you need to get detailed information about how those games are running. In this talk you will learn how AAA studios use PIX in their development process to make their games better. You'll hear about the latest features in both Timing Captures and GPU Captures, as well as what's coming up in 2021 and beyond.
The Unity Physics DOTS package, developed in partnership with Havok, needed to be cache free in order to better support scenarios such as simulation rollback for networked simulations. Stacking rigid bodies tends to require a cache, spanning multiple frames, to produce stable results. Here we will talk through some heuristics needed to resolve this paradox and to achieve a more stable physics simulation without sacrificing performance or adding additional state to the simulation.
Join AMD on an adventure thru "Zen 2" and "Zen 3" processors which power today's game consoles and PCs. Dive into instruction sets, cache hierarchies, resource sharing, and simultaneous multi-threading. Journey across the sands of silicon to master microarchitecture and uncover best practices!
In the pursuit of enabling developers to create the most amazing gaming experiences yet, the Xbox hardware team developed many innovations to deliver the most powerful Xbox ever, the Xbox Series X. We will discuss the silicon and memory architectures that enable a generational leap in GPU, CPU and storage performance. The team will also dive into the features that enabled the console to be cool, quiet and power efficient, such as the innovative tower form factor, split motherboard design, optimized power delivery and the thermal architecture.
Cloud services are critical components of making games today and we expect the reliance on the cloud by game creators to continue to grow in the future. The Game Development Experiences team at Microsoft is investing deeply in our Azure infrastructure to ensure that it meets the demands of game developers around the world. In this talk we'll discuss some of the challenges of working in a decentralized and diverse world and share present and future ideas for how Microsoft can help accelerate the sharing of ideas, code, content, and creativity for game creators of all sizes.

In this session we will highlight what cloud optimizations are possible, how these optimizations are influencing consumer behavior in the current Xbox Game Streaming offerings, and where we see the impact to consumer behavior in the future.
Microsoft Partner Center gives you the ability to publish, or "flight" your titles in the RETAIL environment in a private, secure manner to a controlled audience. This is a great way to validate your builds for a small group. The Xbox Insider Program supercharges this feature and lets you scale your flight to a much larger audience either publicly or privately, with built-in tools to get actionable feedback. This presentation walks you through this flighting process step by step to illustrate just how easy it is.
Game telemetry is a powerful, but underutilized tool in the test/quality space. We aim to flip the status quo of games testing by empowering everyone from developers to active users to contribute to the passive verification of game features and behaviors. We will highlight a method employing the scalability of the Azure ecosystem and flexibility of Python to turn our game telemetry into actionable insights and bugs. Let everyone who touches the game, test the game.
In this presentation, you will learn about building cloud native CI/CD pipelines for Unity mobile game apps with managed services like Azure Pipelines and Visual Studio App Center, as well as setting up cloud ready licensing infrastructure with Unity Build Server.
