The Ultimate Guide to RTGI 01702: How to Download and Install for Stunning Visuals

In the ever-evolving world of PC gaming graphics, few mods have generated as much excitement as Pascal Gilcher’s RTGI (Realtime Global Illumination) shader. This revolutionary ReShade add-on brings a form of ray-traced indirect lighting to hundreds of games, even those released a decade ago.

One of the most requested and community-discussed versions is RTGI 01702. Known for its stability, performance optimizations, and breakthrough “Performance Mode,” this specific build remains a favorite among modders.

If you’ve been searching for a reliable guide on how to complete your rtgi 01702 download install, you’ve come to the right place. This article will walk you through every step, from downloading the correct files to fine-tuning the settings in your favorite game.

Step 5: Configure ReShade to Use RTGI

Launch your game. You should see a ReShade loading message at the top.
Press Home key (default) to open the ReShade overlay.
Go to the “Settings” tab → set “Effect Search Paths” to include .\reshade-shaders\Shaders (should already be correct).
Set “Texture Search Paths” to .\reshade-shaders\Textures.
Switch to the “Home” tab → click “Reload” (or press Ctrl+Home) to compile all shaders.
In the effect list, search for “RTGI”.
Check the box next to RTGI.fx (or qUINT_rtgi.fx). The effect will now be active.

What Exactly is RTGI 01702?

Before touching the installation, let’s clarify what RTGI 01702 is. It is not a standalone program or an .exe file. Rather, it is a collection of ReShade shaders (specifically the .fx files) that simulate realistic bounce lighting, ambient occlusion, and indirect illumination. rtgi 01702 download install

The version number 01702 refers to a specific release from Gilcher’s Patreon (now often available via GitHub or community archives). It is famous for:

Improved Denoising: Less grain compared to earlier versions.
ReSTIR Integration: Better sampling efficiency, meaning higher quality for fewer performance points.
Reduced Fireflies: Minimal bright pixel artifacts that plagued v012 and v014.

Because RTGI is technically a pay-what-you-want product, you can still access 01702 via official channels by subscribing to Pascal Gilcher’s Patreon (as low as $1) or through authorized free distributions after the shader aged out of early access.
