At its core, is a screen-space ray tracing shader. Unlike hardware-native Ray Tracing (found in modern games supporting DXR), screen-space ray tracing does not read the entire 3D geometry of a game world. Instead, it extracts data from the game’s depth buffer —the data sheet that tells your graphics card how close or far objects are from the camera.
Installing RTGI 0.36.1 requires a current installation of ReShade. Note that this shader is typically premium content, available via Pascal Gilcher’s Patreon.
Yes, it costs frames. Yes, it requires tweaking. But the moment you see a sunset in The Witcher 3 actually turning the interior of a wooden cabin a dusty orange through the windows, you realize the cost was worth it. You aren't just playing the game anymore; you are seeing the light the developers intended, but could never afford to render. reshade rtgi 0361
Because RTGI is a paid shader hosted on Pascal Gilcher’s Patreon, you must acquire the shader files ( qquint.fx and its accompanying textures) from his official community channels. Once you have the files for version 0.36.1, follow these steps: Step 1: Install ReShade

This can lead to occasional "flickering" or light disappearing at the edges of the screen. For single-player gaming, RTGI 0.36.1 At its core, is a screen-space ray tracing shader
Take a game like The Elder Scrolls V: Skyrim . It is beautiful, but its lighting engine is over a decade old. Injecting RTGI 0361 transforms the dank, gray dungeons. Now, torchlight bounces off stone walls, illuminating the room with warm, orange hues that the original artists never programmed. It doesn't just make the game look newer; it changes the mood.
The 0.36.x development cycle focused heavily on refinement, stability, and artifact reduction. Version 0.36.1 stabilizes these features, making it one of the most reliable releases for everyday gaming. 1. Advanced Denoiser Filtering Installing RTGI 0
Keep this between 3 and 5 for gameplay. Settings above 8 are intended purely for photography/screenshots and will heavily degrade performance.
This is your primary performance slider. Setting this to Extreme (5 or higher) will tank your framerate with diminishing visual returns. A value of 3 provides excellent performance while relying on the denoiser to clean up the image. Lighting Brightness & Saturation Recommended Value: 1.00 (Adjust based on game engine)
