By following this guide, you not only gain access to one of the most iconic ReShade shaders ever written but also learn the fundamentals of depth buffer manipulation and shader injection.

Remember: the file is small, but the impact is enormous. Whether you are lighting the dusty plains of New Hanover in RDR2 or the neon alleys of Night City, RTGI 01702 remains a testament to what passionate developers can do with open-source graphics APIs.

Final Checklist for Success:

Now go forth and let there be light—ray traced light. Enjoy your high-quality download.

RTGI (Ray Traced Global Illumination) is a shader that simulates how light bounces off surfaces to create realistic lighting and shadows in games that do not natively support hardware-level ray tracing. How To ReShade RTGI - Install and Adjust

If you are looking to elevate your gaming visuals to a photorealistic level, the RTGI 01702 shader—developed by the legendary Pascal Gilcher (McFly)—is the gold standard. This version of the Screen Space Ray Traced Global Illumination (RTGI) shader brings sophisticated lighting techniques to games that don't natively support Ray Tracing. What is RTGI 01702?

RTGI 01702 is a specialized shader for ReShade. Unlike standard lighting effects, it simulates how light bounces off surfaces. This creates realistic shadows, ambient occlusion, and color bleeding.

Global Illumination: Light reflects from one object to another. Ray Tracing: Calculates the path of light in real-time.

Compatibility: Works with almost any DX9, DX11, or DX12 game. Why Choose the 01702 Version?

The "01702" build is highly sought after because it strikes a perfect balance between visual fidelity and performance optimization. Key Enhancements:

Improved Denoising: Reduces the "grainy" look in dark corners.

Better Depth Detection: Avoids light leaking through thin walls.

Optimized Performance: Runs smoother on mid-range GPUs compared to older beta builds.

High Quality Presets: Offers cleaner gradients and more accurate light bounces. How to Download RTGI 01702 (High Quality)

To ensure you are getting the authentic, high-quality file and supporting the creator, follow these steps: Official Source: Visit Pascal Gilcher’s Patreon.

Tier Access: You typically need the "Beta Access" tier to download the latest RTGI builds.

File Contents: Your download should include a .fx shader file and a .fxh header file.

Avoid Malware: Be cautious of "free" third-party links, as these often contain outdated or compromised files. Installation Guide

Setting up RTGI 01702 requires a few manual steps to ensure the "High Quality" settings actually trigger.

Install ReShade: Download it from the official site and point it to your game’s .exe.

Add Files: Drop the RTGI.fx and RTGI.fxh into your game's reshade-shaders/Shaders folder.

Enable Depth Buffer: Inside the ReShade menu (Home key), ensure the "Edit Global Processor Definitions" has RESHADE_DEPTH_INPUT_IS_REVERSED set correctly for your game. Configure RTGI: Check the "RTGI" box in the ReShade list. Best Settings for High Quality Visuals

To get the most out of the 01702 build, tweak these parameters in the ReShade UI:

Ray Length: Set between 10.0 and 20.0 for natural light spread.

Ray Amount: Increase to 3 or 4 for smoother shadows (hits FPS harder).

Z-Thickness: Adjust to prevent light from "bleeding" through objects.

Enable Infinite Bounces: This adds a second layer of light reflection for maximum realism.

🏆 Pro Tip: Always disable In-Game Anti-Aliasing (like MSAA) if your depth buffer isn't working; ReShade needs access to depth data to calculate Ray Tracing.

First, let's clarify the terminology. "RTGI" stands for Ray Traced Global Illumination. Unlike screen-space ambient occlusion (SSAO) or basic bloom effects, RTGI simulates how light bounces off surfaces in a 3D space, creating subtle color bleeding, realistic shadow softening, and ambient occlusion that reacts to the environment.

The code string "01702" refers to a specific build of the shader. In the world of ReShade shaders, version numbers are critical. Version 01702 (often formatted as 0.17.0.2) is considered by many visual enthusiasts to be the "sweet spot" update. It offered:

This version is particularly famous for its use in Cyberpunk 2077 (pre-1.6 patch), Red Dead Redemption 2, and The Witcher 3 modding scenes. When users demand an RTGI 01702 download high quality, they aren't just looking for any file—they want the pristine, unmodified shader that delivers that "next-gen" toggle feeling without unnecessary feature creep.

What is RTGI 0.17.02? Version 0.17.02 is a specific legacy build of the Marty McFly Ray Traced Global Illumination shader. While newer versions exist, many users prefer specific older builds like 0.17.02 because they offer a specific balance of performance and visual stability, or because they are the last version compatible with certain hardware or API setups.

If you are looking to download this specific version for high-quality gaming visuals, here is what you need to know.

The demand for a "high quality download" highlights a fascinating shift in how we consume digital media. We are moving away from streaming (where compression artifacts hide the details) back toward ownership.

If you are downloading an RTGI demonstration, you are doing so because compression algorithms on streaming sites crush the subtle lighting data that makes Ray Tracing impressive. You want to see the noise patterns, the color bleed, and the shadow softness exactly as the renderer intended.
