| Pros | Cons | | :--- | :--- | | Can make 10-year-old games look modern and cinematic. | Screen-Space Artifacts: Light bleeding can occur on edges of the screen or when the camera moves quickly (though v0.33 handles this well). | | Free Access: v0.33 provides high-end features without the Patreon paywall. | Performance Hit: Can reduce FPS by 20-40% depending on settings and resolution. | | Wide Compatibility: Works on almost any game that supports ReShade (DX9-DX12). | Complex Setup: Requires understanding depth buffer settings to avoid UI artifacts or lighting glitches. | | Customizable: Extensive variables allow users to tweak light intensity, bounce strength, and sky color. | Not "True" RT: It does not reflect objects outside the camera view or handle transparent objects perfectly. | reshade ray tracing shader rtgi 033 free
For years, the holy grail of PC gaming graphics was locked behind expensive hardware and “RTX On” marketing campaigns. But what if you could experience the magic of realistic global illumination, bounced lighting, and ambient occlusion on an older GTX card, an AMD GPU, or even an Intel Arc? Enter the world of , and specifically, the legendary RTGI 0.33 Free version.

The future of RTGI is incredibly bright, thanks to two major developments:
By operating on depth data alone, RTGI is fully compatible with from NVIDIA, AMD, and Intel, and has no inherent hardware feature requirements. Users with GPUs ranging from an RTX 5090 all the way down to integrated graphics can, in theory, run the shader. Optimization and Tweaking Settings | Pros | Cons
The shader by developer Pascal Gilcher (alias Marty McFly ) is widely considered the "gold standard" for software-based ray tracing in post-processing. Version 0.33 represents a specific, highly stable public release that dramatically enhances lighting in older games or titles lacking native ray tracing support. Unlike the paid Patreon builds, v0.33 is available for free and brings realistic light bouncing and soft shadows to a vast library of games with minimal performance overhead compared to hardware-accelerated ray tracing.
Locate your game installation directory where ReShade is installed. Open the reshade-shaders folder. Move the RTGI .fx file into the Shaders subfolder.
