Obtain the latest RTGI shader pack (0.361 or later) from Marty's Mods.
The configuration—often found in the settings GUI—refers to a combination of higher ray counts, increased temporal accumulation, and better precision in occlusion calculations.

The shader only calculates data visible on your screen. Objects hidden behind UI elements or off-camera do not cast rays. Hardware Requirements & Performance Impact reshade rtgi 0361 extra quality
Controls how many rays are cast per pixel. Higher numbers completely eliminate grainy shadows but drastically reduce framerates.
The "0.36.1" version—specifically the "Extra Quality" or high-end presets—is known for significantly enhancing scene depth and light interaction, though it comes with notable technical caveats. Key Performance & Visual Quality Highlights Realistic Light Bouncing
Disable anti-aliasing modes like MSAA or SSAA in the game menu. Use TAA or FXAA instead. Obtain the latest RTGI shader pack (0
| Setting | Recommended Value (Extra Quality) | Explanation | | :--- | :--- | :--- | | | SophiaG | This is the most crucial setting. As mentioned, SophiaG sacrifices convergence speed for higher quality minima, leading to superior lighting. | | Number of Rays | 6 - 10 | Controls the number of sample rays per pixel. Higher values drastically reduce noise and flicker but have a linear performance cost. | | Number of Steps per Ray | 32 - 64 | Controls the precision of each ray. Higher steps prevent light leaks and improve contact shadows. Start high and lower until fine details remain stable. | | Ray Length | 0.50 - 1.00 | Determines how far rays travel. Longer rays capture more global illumination (color bouncing) but can lead to off-screen artifacts if too high. | | Z-Thickness | 0.25 - 0.50 | A critical parameter that informs the shader about the thickness of objects. Incorrect values can cause dark halos or faint lighting. | | Resolution Scale | Half-Rate or Quarter-Rate | For "Extra Quality" on high-end GPUs, Half-Rate is often the best compromise. Setting it to Quarter-Rate can help with performance on lower-end cards. | | Display Depth | Disabled | This is a debugging tool that shows the depth buffer. Make sure it's off to see the RTGI effect. |
To get the absolute best picture quality out of version 0.36.1, open the shader parameters at the bottom of the ReShade menu and adjust the following settings:
Because it operates on depth buffer data, RTGI is fully compatible with non-RTX video cards, though it is demanding on GPU resources. Objects hidden behind UI elements or off-camera do
Includes higher sample counts and improved denoising filters to reduce the "flickering" or noise often associated with screen-space ray tracing.
ReShade RTGI 0.36.1 remains a beloved version because it offers a balanced foundation for screen-space ray tracing. Whether you're chasing "extra quality" through custom presets or manual tuning, the principles are the same:
If you experience stuttering, lower the slightly before lowering the Resolution Scale . A full-resolution render with fewer rays looks cleaner than a half-resolution render with high ray counts. Troubleshooting Common Issues Light Leaking Symptom: Light shines through solid objects or walls.
ReShade is a popular post-processing injector that allows users to enhance the graphics of their games. RTGI (Real-Time Global Illumination) is a feature that simulates realistic lighting, making your games look more stunning and lifelike.
The effect, created by , accurately models both diffuse and specular global illumination, resulting in temporally stable lighting that minimizes flickering. Because it operates on depth data alone, RTGI is remarkably hardware-agnostic and compatible with non-RTX video cards, although ray tracing remains computationally demanding.
