Shaders are specialized programs that run on the GPU that manipulate rays, pixels, vertices, and textures to achieve unique visual effects. They’re essential in raytracing for simulating realistic lighting, shadows, and reflections. We love shaders, but they can be hard to debug.
As raytracing becomes the predominant rendering technique in modern game engines, a single GPU RayGen shader can now perform most of the light simulation of a. As raytracing becomes the predominant rendering technique in modern game engines, a single GPU RayGen shader can now perform most of the light simulation of a frame.
[stextbox id="info"]This post is an update of Best Practices: Using NVIDIA RTX RayTracing.[/stextbox] This post is an update of Best Practices: Using NVIDIA RTX RayTracing. This post gathers best practices based on our experiences so far using NVIDIA RTX raytracing in games.
Today, developers can access the latest versions of RTX Global Illumination (RTXGI), RTX Direct Illumination (RTXDI), NVIDIA Real-Time Denoisers (NRD), and OptiX RayTracing Engine (OptiX). NVIDIA OptiX RayTracing Engine 7.4 also received performance improvements to the demand loading library, ray payloads, and curves.
Easier ray-tracing integration for games with Kickstart RT In 2018, NVIDIA Turing architecture changed the game with real-time raytracing. This scene highlights raytracing, global illumination, ambient occlusion, and raytraced shadows, enabled through KickStart SDK. Unreal Engine 4.27
NVIDIA Nsight Developer Tools provide comprehensive access to NVIDIA GPUs and graphics APIs for performance analysis, optimization, and debugging activities.

Increasingly, game developers are making full use of real-time raytracing and AI in their games. Increasingly, game developers are making full use of real-time raytracing and AI in their games. Now, NVIDIA raytracing and AI are making their premiere on Arm and Linux systems.
NvRTX Artist Guide Learn more about the NVIDIA RTX Unreal Engine Branch (NvRTX), and discover technologies such as RTXDI, RTXGI, new denoisers like Relax, ray-traced volumetrics and tools like the BVH viewer. This session will cover several challenges developers can encounter when working to deploy raytracing in a game environment.
Branch offers all of the benefits of mainline UE4.26, while providing some additional features: Faster raytracing NVRTX includes a number of improvements to raytracing performance. Hybrid Translucency Another way to do raytraced translucency, with greater compatibility, speed and rendering options.
Good developer tools are like an x-ray machine that allows you to peek into the internals of the GPU. There is always some layer of abstraction between the physical computer and the application that you are building, but you can’t optimize and debug what you can’t see.
Featuring third-generation RayTracing Cores and fourth-generation Tensor Cores, they accelerate games that take advantage of the latest neural graphics and raytracing technology. The latest suite of technologies multiply performance in games while accelerating how quickly developers can create content.
NVIDIA RTX Path Tracing is the ultimate solution for raytracing. What challenges did you face during the process of integrating raytracing? New technologies generally bring new problems, and the debugging process is particularly more difficult. How has path tracing affected your visuals and gameplay?
Learn About New SDKS Built For Real-Time RayTracing and More From March 15-19, GDC Showcase will introduce a wide range of new content for game developers to. Learn About New SDKS Built For Real-Time RayTracing and More From March 15-19, GDC Showcase will introduce a wide range of new content for game developers to explore.
Developers can apply now for access to RTX Direct Illumination (RTXDI), the latest advancement in real-time raytracing. REAL TIME RAYTRACING MADE EASIER RTX Direct Illumination (RTXDI) Imagine adding millions of dynamic lights to your game environments without worrying about performance or resource constraints.
UE4 plugin (Download here ) Leveraging the power of raytracing, RTXGI provides scalable solutions to compute multi-bounce indirect lighting without bake times, light leaks, or expensive per-frame costs. It gives you the performance headroom to maximize raytracing settings and increase output resolution. RTXGI 1.1.40
DLSS pairs perfectly with computationally intensive rendering algorithms such as real-time raytracing. NVIDIA Reflex NVIDIA Reflex is a toolkit to measure, debug and improve CPU+GPU latency in competitive multiplayer games. Raytracing and DLSS are supported in the biggest PC game launch ever – Cyberpunk 2077.
With DLSS, users can maximize ray-tracing settings and increase output resolution. In addition to latency reduction functions, the SDK also features measurement markers to calculate both Game and Render Latency — this feature is great for debugging and visualizing in-game performance counters.
The first open-source release of GPU kernel modules for NVIDIA GPUs in Linux creates tighter integration with the OS and enables developers to debug, integrate, and contribute back. Unreal Engine 5 supports key RTX technologies for developers to propel their games and experiences to deliver cutting-edge content and immersive virtual worlds.
NetEase Thunder Fire Games Uses Mesh Shading To Create Beautiful Game Environments for Justice In December, we interviewed Haiyong Qian , NetEase Game Engine Development Researcher and Manager of NetEase Thunder Fire Games Technical Center, to see what he’s learned as the Justice team added NVIDIA ray-tracing solutions to their development pipeline.
THE FINALS | Beta Gameplay with DLSS 3, RayTracing, and NVIDIA Reflex The DLSS Super Resolution plugin supports a variety of image quality modes—from Ultra Performance to Quality—determined by the native resolution relative to the DLSS output resolution. Toggle the Load Debug Overlay option.
For more information about GPU Trace and its many applications, see the following resources: Advanced API Performance: Async Compute and Overlap Identifying Shader Limiters with the Shader Profiler in NVIDIA Nsight Graphics Building Acceleration Structures Using Async Compute (video) How to Improve Shader Performance by Resolving LDC Divergence (video) (..)
The main goal of my GSoC project is to completely rewrite the light mapper in Godot and, instead of a voxel approach, use raytracing to compute the scene lighting. I'm currently working on integrating Embree as a raytracing library into the Godot editor. These can only be dealt with manually while debugging.
Great for debugging and for real time in-game overlays. Latency Markers – Real time latency metrics broken down by game pipeline stage: Input, Simulation, Render Submission, Graphics Driver, Render Queue, and GPU Render. This is helpful when automating the use of a tool like the NVIDIA Reflex Latency Analyzer to measure latency.
