NVIDIA RTX Path Tracing SDK
The NVIDIA RTX™ Path Tracing Software Development Kit (SDK) merges years of best practices within real-time ray tracing and neural graphics development for building a real-time path tracer.Access RTX Path Tracing SDK Introductory Resources
Explore the Benefits of the RTX Path Tracing SDK
Ground Truth Lighting in Real Time
Whether you’re rasterizing, tracing rays, or both, this SDK provides the tools and sample code to build an interactive physically-accurate reference renderer to aid in your development, ensuring your lighting during production is true to life.
Highly Customizable Toolkit
This SDK gives you the flexibility to take individual components that suit your needs or take the entire path tracer and integrate it directly into your game engine.
Ultra-Realism Mode for Your Game
This path tracer leverages new hardware in NVIDIA GeForce RTX® 40 Series GPUs, allowing you to provide the highest-quality rendering modes with uncompromised performance.

NVIDIA DLSS (Deep Learning Super Sampling) is a neural graphics technology that multiplies performance using AI to create entirely new frames and display higher resolution through image reconstruction—all while delivering best-in-class image quality and responsiveness.Get Started with DLSS
Shader Execution Reordering (SER)
NVIDIA Shader Execution Reordering is an API extension that optimizes execution of ray-traced workloads to achieve maximum parallelism and performance from ray traced shaders.Download NVAPI (SER will be made available through NVAPI soon)
RTX Direct Illumination (RTXDI)
NVIDIA RTXDI is a ray-tracing library that renders millions of dynamic lights and shadows in a scene without performance hits. RTXDI is accelerated by RT Cores in RTX GPUs.Get Started with RTXDI
NVIDIA Real-Time Denoisers (NRD) is a cross-platform denoising library for ray-traced lighting, shadows, and ambient occlusion. It provides fast and uncompromised image quality for when you have a limited budget of rays per pixel.Get Started with NRD
