shader to help RTGI track pixel movement, significantly reducing flickering and ghosting while reclaiming some FPS. Hardware Independence
Download the latest version of ReShade with . This version is mandatory to access depth buffers in multiplayer or protected games offline. Run the installer and select your game's executable (.exe).
Before setting up RTGI, ensure your system and game meet these three prerequisites:
To appreciate version 0.33, you must understand how a post-processing shader achieves what used to require dedicated RT cores:
| Setting | Low Impact (60 FPS) | High Quality (30 FPS) | Explanation | | :--- | :--- | :--- | :--- | | | 0.10 - 0.15 | 0.25 - 0.40 | How far light bounces. Longer = more bounce, but more noise. | | Ray Count | 2 - 3 | 6 - 8 | The killer setting. Keep at 2 for 1080p. Raise to 4 for 1440p. | | Bounces | 1 | 2 | Secondary bounces. For 0.33, stick to 1 unless on a 4090. | | TAA Strength | 0.85 | 0.70 | Higher TAA reduces flicker but adds ghosting. 0.85 is safe. | | Intensity | 1.0 | 1.5 | General brightness of the bounced light. | Reshade Ray Tracing shader RTGI 0.33
Once RTGI is installed and running, the real magic happens in the configuration. Getting the look just right for your specific game requires adjusting a few key parameters.
Multiplayer games with anti-cheat software usually disable depth buffer access to prevent wallhacks.
The world of ray tracing and global illumination is rapidly evolving, with new technologies and techniques emerging regularly. As developers continue to push the boundaries of what's possible, we can expect even more impressive advancements in the field. Some potential future developments for RTGI include:

To use RTGI 0.33, you need the shader files (available via Marty McFly's Patreon) and a compatible version of ReShade. Step 1: Install ReShade
Light bounces off colored surfaces and naturally tints neighboring objects.
Because ReShade processes the image after the game renders it, shaders naturally apply to HUD elements and text. To fix this, download and install the or a game-specific HUD-masking shader to protect UI elements.
Simultaneously calculates soft light bounces (diffuse) and sharper reflections (specular) to bridge the gap between old game engines and modern lighting. 18;write_to_target_document7;default0;4c0;18;write_to_target_document1a;_fonuaYbjLYWFkdUP-8C96AM_20;2a; Performance vs. Quality Trade-offs 0;16; Run the installer and select your game's executable (
Enter Marty McFly’s (Pascal Gilcher) . This post-processing tool injects real-time, software-based ray-traced global illumination into almost any 3D game. It bridges the gap between generational hardware and delivers stunning, photorealistic lighting without requiring an Nvidia RTX or AMD RX GPU. What is ReShade RTGI 0.33?
RTGI is demanding. If you experience a significant drop in frames per second (FPS), there are ways to optimize performance. The most common method involves adjusting the shader's render resolution within ReShade's in-game UI.
