: While it does not require RT cores, RTGI is demanding. A mid-range GPU (like a GTX 1070, RTX 2060, or RX 5700) is recommended for stable framerates.
This guide breaks down everything you need to know about this sought-after version, from understanding its core technology to practical installation, configuration, performance tips, and the legal ways to access it today.
Because version 0.33 was a specific milestone release, you need to manually place its files into your game directory once you acquire the standalone shader files:
uniform float fRTGI_RayLength < ui_label = "Ray Length"; ui_min = 0.1; ui_max = 5.0; > = 1.0; reshade ray tracing shader rtgi 033 free
Search for "Pascal Gilcher RTGI 0.33 GitHub" directly. The repository file will end in .fx or .fxh . Place these files in your ReShade Shaders/Shaders folder.
: Optimization tweaks that reduce the heavy frame-rate drop seen in older versions.
Check the box for DisplayDepth in the shader list to test your depth buffer. : While it does not require RT cores, RTGI is demanding
If your depth buffer looks inverted or broken (e.g., you can see through walls), go to the tab, look at the global processors at the bottom, and toggle RESHADE_DEPTH_IS_REVERSED between 0 and 1 .
Because RTGI runs purely as a screen-space post-processing effect based on depth buffer data, it does not use physical hardware RT cores. This means you can achieve ray-traced global illumination on older NVIDIA GTX cards or AMD Radeon hardware. Key Visual Enhancements of RTGI
First, ensure you have the latest version of ReShade (with add-on support) installed for the specific game's executable you want to mod. Because version 0
Disable any in-game Anti-Aliasing (like MSAA) and native Ambient Occlusion, as they often block ReShade from reading the depth buffer. Optimizing RTGI for the Best Performance
