: RTGI is a paid modification. You must join a specific membership tier on Patreon to unlock the download link for the ReShade GI Beta 0.17.0.2.zip Safety Warning
The most secure method is to download the file directly from the creator. The Pascal Gilcher Patreon RTGI 0.17.0.2 Release Post contains the authorized attachment. Accessing this specific tier requires a subscription, which directly supports the shader's ongoing development. 2. Free Alternatives: NVIDIA SSRTGI
The RTGI shader acts as a universal post-processing injector. It intercepts the game’s 3D engine depth buffer and simulates how light bounce, diffuse illumination, and physical shadows behave in real time. rtgi 0.17.0.2 download
Screen-space ray tracing is heavy on the hardware. This version introduced tweaks to help maintain a playable framerate while still delivering high-quality light bounces.
Download and run the latest ReShade installer. Select your game's .exe and the correct API (DirectX 11, DirectX 12, or Vulkan).
RTGI stands for . Unlike native hardware-driven ray tracing (like Nvidia RTX or AMD DXR) which utilizes specialized RT cores to track geometric data across an entire game engine, RTGI works through ReShade , a universal post-processing injector. You must join a specific membership tier on
Choose the correct rendering API for your game (DirectX 9, DirectX 11, DirectX 12, or Vulkan).
: Unlike official RTX implementations, this shader operates on "Screen Space" data, meaning it can run on non-RTX graphics cards as long as the user can access the game's depth buffer.
: Soft, realistic shadows are cast in corners, crevices, and contact points. and Ambient Occlusion
Ensure the depth buffer matches your game resolution. Turn off in-game Anti-Aliasing (MSAA) if the depth map looks blank. Performance Tuning Tips
Ray Traced Global Illumination (RTGI) is a screen-space shader that simulates the complex behavior of light. Unlike simpler methods like Screen Space Ambient Occlusion (SSAO), which only approximates shadows in creases and corners, RTGI accurately models how light bounces off surfaces, contributing to a more immersive and physically accurate scene.
To use RTGI, you must first install ReShade. Follow these steps to get everything running perfectly. Step 1: Install ReShade
If you want, I can:
In your game's in-game video settings, and Ambient Occlusion , as these can blur or disable the depth buffer. Best Settings for Performance and Visuals
