Determines how many samples are tracked per ray. Higher numbers directly reduce visual noise and graininess at the cost of your frame rate. Version 0.33 introduces highly optimized spatial filtering, allowing you to use moderate ray amounts (e.g., 3 to 5) while relying on denoisers to smooth out the image. Ray Miss Color (Sky Color)
Games like The Witcher 3 (classic version) or Grand Theft Auto V look staggeringly lifelike when forest canopies accurately cast soft, layered shadows and city asphalt reflects neon store signs.
Motion vectors allow the shader to track object movement relative to the camera, significantly reducing the "ghosting" or "trailing" artifacts common in earlier versions. Improved Temporal Accumulation:
RTGI 0.33 accurately models both diffuse (soft, bounced light) and specular (shiny reflections) global illumination. How RTGI Transforms Your Game
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.

Run the installer, select your game’s executable (.exe) file, and choose the correct rendering API (DirectX 11, DirectX 12, or Vulkan).
: Essential for preventing light from "leaking" through thin walls. Performance Considerations ReShade 5.3 and RTGI 0.33 Update | August 2022
Reshade RTGI 0.33 bridges the gap between classic game design and next-generation lighting tech. It gives titles like Skyrim , Grand Theft Auto V , Batman: Arkham Asylum , and Dark Souls a fresh, modern atmosphere that rivals native remaster efforts. By mastering the depth buffer settings and finding the right balance of ray lengths, any PC player can experience the immersive beauty of real-time global illumination.
Just don’t expect path tracing. And definitely don’t expect 120 FPS. But for the 90% of games that will never see a native RTX update? RTGI 0.33 is the next best thing — and sometimes, it’s even better. Determines how many samples are tracked per ray
Elevating Gaming Visuals: A Deep Dive into ReShade RTGI 0.33
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 .
Because RTGI 0.33 is a "deep" shader that essentially recalculates light for the entire screen, it is very demanding. You will likely see: 0;16;
Because RTGI relies on mathematical algorithms and depth data rather than dedicated RT cores, it works on almost any graphics card, including AMD, Intel, or older Nvidia 1000-series cards. This is a huge advantage over the proprietary RTX solutions, democratizing ray tracing for the masses. Ray Miss Color (Sky Color) Games like The
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.
Like any powerful tool, RTGI 0.33 isn't without its quirks. The community feedback on the RTGI shader series, including 0.33, is generally positive but highlights a few common issues.
Reshade RTGI 0.33 is the premier tool for gamers who want to bring modern, dynamic lighting into their existing game libraries. Its advancements in motion tracking and noise reduction make it a crucial upgrade over previous versions. While it requires a powerful GPU and careful setup, the visual improvement is unmatched in the world of post-processing.
