Shaders are specialized programs that run on the GPU that manipulate rays, pixels, vertices, and textures to achieve unique visual effects. With shaders, you can add creative expression and realism to the rendered image. They’re essential in raytracing for simulating realistic lighting, shadows, and reflections.

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.
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). The Sun Temple scene from ORCA rendered in real time using RTXDI. NVIDIA OptiX RayTracing Engine 7.4 NVIDIA OptiX 7.4
At Unite 2024, Unity’s development team introduced a series of advanced GPU optimization techniques aimed at improving rendering performance across various platforms. One of the fundamental challenges in real-time rendering is reducing GPU latency to improve frame rate. Another important consideration is transparency.
It sits between the game and render API, and abstracts the SDK-specific API calls into an easy-to-use Streamline framework. Streamline’s plug-and-play framework sits between the game and render API. This scene highlights raytracing, global illumination, ambient occlusion, and raytraced shadows, enabled through KickStart SDK.
NVIDIA at GDC 2023: Frame Generation and Path Tracing Tools Now Available Generate frames with the latest breakthrough in AI rendering Announced with the NVIDIA Ada Lovelace architecture, DLSS 3 raised the bar not just for visuals but also performance and responsiveness. Frame generation is the latest evolution.
NVIDIA Nsight Developer Tools provide comprehensive access to NVIDIA GPUs and graphics APIs for performance analysis, optimization, and debugging activities.

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.
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.
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.
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
NVIDIA RTX Path Tracing is the ultimate solution for raytracing. The rendering pipeline of Justice is built on physically based rendering (PBR). Realistic physical illumination is naturally implemented with path tracing, which improves visual appeal and reduces defects.
Featuring third-generation RayTracing Cores and fourth-generation Tensor Cores, they accelerate games that take advantage of the latest neural graphics and raytracing technology. It delivers up to 4x improvements in frame rate and up to 2x improvements in latency compared to native resolution rendering.
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.
NVIDIA set out to redefine real-time rendering through AI-based super resolution — rendering a fraction of the original pixels and then using AI to reconstruct sharp, higher resolution images. With DLSS, users can maximize ray-tracing settings and increase output resolution.
As a result, running with a Debug build of an application may result in less optimal GPU workloads, for instance. Continue to render frames until wantMoreFrames is returned as false. Even for a Release build, the driver background optimizations may be turned on and off dynamically from frame to frame.
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.
Frame Generation uses AI rendering to generate entirely new frames with best-in-class quality and responsiveness. Powered by these three technologies, DLSS 3 enables upwards of 4x performance boosts, providing headroom for next-generation, path-tracedrendering. Toggle the Load Debug Overlay option. is now available.
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. NVIDIA Releases Open-Source GPU Kernel Modules. Getting Started with NVIDIA Instant NeRF.
The NVIDIA Reflex SDK offers developers: Low Latency Mode – Aligns game engine work to complete just-in-time for rendering, eliminating the GPU render queue and reducing CPU back pressure in GPU-bound scenarios, thus reducing latency in GPU bound scenarios. Great for debugging and for real time in-game overlays.

This means having lots of lights no longer creates a performance hit on the rendering pipeline, since all we need to do is sample a single texture and we get the amount of light coming from all light sources. I'm currently working on integrating Embree as a raytracing library into the Godot editor. Current progress. Next steps.
There were a few things I think I could have done better which would involve a better testing and debugging setup. Setting up the debugging caused me to waste some of my time, and I should probably have had a testing workflow prepared for stress testing the changes I was going to make. About the project experience. Minor regrets.
