Next-Gen Visuals on a Budget: The Ultimate Guide to ReShade RTGI 0.33
Setting up RTGI 0.33 requires a few precise steps to ensure the shader can "see" your game's world correctly.
Reshade’s RTGI 0.33 shader represents a significant step forward in the modding community’s ongoing effort to bring more realistic lighting to games that lack native ray tracing. RTGI (Ray-Traced Global Illumination) is designed to approximate complex light transport — indirect lighting, color bleeding, soft interreflections, and subtle occlusion — by using screen-space techniques and clever temporal accumulation rather than full hardware ray tracing. Version 0.33 refines that approach, balancing visual fidelity, performance, and compatibility for a wide range of titles and systems.
Low / Medium / High now actually mean something. uses 8 samples per pixel and two bounces — heavy but gorgeous. Low drops to 4 samples and one bounce, perfect for 60+ FPS in most games.
Stands for Ray Traced Global Illumination . This is the specific shader made by developer Pascal “Marty McFly” Gilcher . It bounces light in screen space to simulate indirect lighting, making shadows and colors look more natural. Reshade Ray Tracing shader RTGI 0.33
Marty has optimized the compute shaders. On an RTX 3060 or RX 6700, the performance hit is still noticeable (expect a 15-30% FPS drop depending on your resolution), but it is smoother than previous builds. 0.33 feels leaner, allowing for lower "Ray Length" settings without breaking the ambient occlusion.
It guesses based on the brightest pixel.
If you want to tailor this setup for a specific game, let me know you are modding, your GPU model , and if you need help with UI masking or depth buffer alignment .
But RTGI 0.33 runs on , doesn’t require a 5-minute shader compilation, and costs a fraction of the performance. More importantly, it works in literally any DirectX 9–12 or Vulkan game . Next-Gen Visuals on a Budget: The Ultimate Guide
RTGI (Ray Traced Global Illumination) is a post-processing shader that uses the of a game to simulate how light bounces off surfaces. Unlike hardware-native ray tracing (like NVIDIA RTX), RTGI works on almost any modern GPU by calculating lighting based on what is visible on your screen (screen-space). Key Features of Version 0.33:
Unlike basic ambient occlusion, which only darkens corners, RTGI calculates bounced light. If a bright red light hits a white concrete wall, the white wall realistically absorbs and reflects a subtle red hue. RTGI 0.33 improves the accuracy of these calculations, eliminating the "glow" artifacts common in older shader versions. 2. Prerequisites and Requirements
Note: This shader is Patreon-exclusive software. Ensure you are supporting the developer for access to the latest builds and bug fixes.

You cannot just toggle RTGI 0.33 on and expect miracles. The default settings are usually too aggressive. Use this tuning matrix for 60 FPS gameplay on an RTX 3060 / RX 5700 XT.
The result is a transformative experience for older titles. Games like Skyrim or The Witcher 3 gain a sense of physical "grounding" that was previously impossible. Objects no longer look like they are floating; they feel integrated into the atmosphere. The 0.33 update specifically helped in making these transitions look natural, moving away from the overly dark, "crushed" shadows of early ray-tracing mods toward a more balanced, cinematic look. Conclusion
The shader requires a "clean" depth buffer. If a game has a flickering UI or uses certain anti-aliasing techniques that obscure depth data, the effect may break or "bleed" through menus.
