Because it was purely screen-space, anything off-screen (e.g., a bright light behind the camera) couldn’t contribute – a known limitation. Yet, for first-person games where the camera moves often, the effect felt surprisingly natural.

Fire up ReShade, drop in the 0.33 RTGI shader, and watch your shadows come to life.

The 2021 community found RTGI transformative in titles with static lighting or no GI at all:

If the depth map looks inverted or broken, toggle RESHADE_DEPTH_IS_REVERSED or RESHADE_DEPTH_INPUT_IS_UPSIDE_DOWN in the settings. Optimizing RTGI 0.33 Settings

Traditional video game graphics utilize pre-baked lighting maps or screen-space ambient occlusion (SSAO) to simulate depth and shadow. While fast, these methods cannot calculate true indirect lighting—such as a bright red wall casting a warm pink glow onto a white marble floor. How RTGI Works

By late 2022, the author had moved on to a commercial product – became part of the Martymod suite, still available for patrons. However, v0.33 remains downloadable from community archives as the last open version.

Place the McFlyPG_RayTracing.fx file into your game's reshade-shaders/Shaders folder. Move the corresponding .fxh texture and header files into the reshade-shaders/Textures folder. 3. Configuring the Depth Buffer

In 2021, v0.33 was the public iteration that solidified the "Marty McFly" (Pascal Gilcher) lighting formula. It brought features that mimicked the global illumination found in engines like Unreal Engine 5 or NVIDIA’s RTX implementations, but through a software layer that works on almost any GPU.
