Simulates how light reflects off multiple surfaces, making colorful environments pop as light bleeds from bright floors onto walls. Hardware and Software Requirements
RTGI, or Ray Traced Global Illumination, is a more advanced technique that attempts to simulate the physical behavior of light. It traces the path of rays of light from the camera, calculating how they would bounce off surfaces. This creates much more realistic indirect lighting, with light spilling onto nearby surfaces and shadows becoming softer and more natural.

Traditional screen-space post-processing tools modify color tones or push basic contrast layers. ReShade RTGI modifies the engine scene at a foundational rendering stage through three core subsystems: reshade rtgi 0361 full
Since the RTGI 0.36.1 version, the shader has evolved significantly. The newest shader suite from Marty McFly is called , which is the successor to qUINT. The latest versions of RTGI are now part of the iMMERSE Pro and iMMERSE Ultimate packages.
The Ultimate Guide to ReShade RTGI 0.36.1 Full: Bringing Ray Tracing to Any Game
💡 ReShade RTGI is a sophisticated lighting simulation that can dramatically enhance a game's atmosphere and depth, but it's a screen-space technique, not a full, hardware-accelerated ray-tracing solution. Simulates how light reflects off multiple surfaces, making
In the context of ReShade, the "full" version of RTGI 0.36.1 offered specific technical characteristics that made it a favorite among modders and gamers alike.
A bright red wall will naturally reflect a soft red hue onto a white floor next to it.
Unlike native hardware ray tracing (like NVIDIA's RTX), RTGI is . It works by analyzing the "depth buffer" of a game—the data that tells the computer how far away objects are from the camera—to calculate where light should bounce and where shadows should fall. This creates much more realistic indirect lighting, with
: Calculates soft, realistic shadows where geometric planes intersect. It handles dark crevices, clothing folds, and fine details with vastly superior depth compared to vanilla SSAO or HBAO techniques.
Determines how far light can bounce. A lower value is faster and often sufficient.
Verify that your depth buffer is working correctly. If the depth map is completely black or white, disable anti-aliasing (MSAA) in the game's display settings. Many older game engines disable depth access when hardware anti-aliasing is turned on.
This indicates that ReShade does not have access to the depth buffer. Check the Add-on tab, disable anti-aliasing (MSAA) in your game's video settings, and disable any scaling overlays like Discord or GeForce Experience.
Does it replace a native, hardware-accelerated RTX implementation? No. It runs in screen-space, it eats FPS for breakfast, and it can flicker if you don't tweak it right. But it allows a player with a GTX 1060 or a Radeon 5700 XT to experience bounce lighting, realistic ambient occlusion, and immersive color bleed in games that were never designed to have them.
