Software rot is real. Newer drivers break old shaders. Windows updates cause flickering. Yet, the community maintains a simple mantra: If it works, don't update it.
The keyword "reshade rtgi 0361" points directly to a specific shader file: .
Launch the game, open the ReShade menu (default key Home ), and check the McFlyPG_RTGI.fx box.
What are you planning to use RTGI 0.36.1 with? What are your graphics card (GPU) specs? reshade rtgi 0361
Version 0.36.1 introduced critical optimizations over older builds. It streamlined the temporal filtering (denoising) to reduce the "ghosting" artifacts common in earlier versions. It also optimized ray-marching steps, giving users better performance per ray than previous iterations. Prerequisites and Performance Impact
Move the RTGI 0.36.1 qquint_rtgi.fx file into the reshade-shaders/Shaders folder.
Unlike screen-space techniques (like SSAO) that only darken corners, RTGI 0.36.1 computes actual rays to determine how light travels from a source, hits surfaces, and illuminates dark areas. As of late 2025/early 2026, the technology has evolved toward spectral rendering to improve saturation in colored scenes, but 0.36.1 remains a robust and high-performing version of the core Marty McFly RTGI technology. Key Features and Improvements in 0.36.1 Software rot is real
Path-Traced Screen-Space Global Illumination (SSGI) in Generic Post-Processing Injectors Author Reference: Based on the work of Pascal Gilcher ( Marty's Mods ) 1. Abstract
: It significantly improves the depth and realism of lighting in older titles like Guild Wars 2 Limitation
Download the latest ReShade (6.0+ recommended) from the official site. Run the installer, select your game executable, and choose the correct API (DX10/11/12 or Vulkan). Yet, the community maintains a simple mantra: If
: For many users, 0.36.1 represents a stable middle ground. It is advanced enough to include all the core RTGI features (global illumination, enhanced ambient occlusion, improved reflections) without some of the early teething issues of newer implementations. It is widely compatible with a huge range of games, from X-Plane 11 and Dead Space 2 to Stellar Blade and The Last of Us Part I .
The shader is better at analyzing depth maps and normal maps from the game, ensuring that light does not shine through thin walls or behave unrealistically in dark environments. How to Install and Set Up RTGI 0.36.1
The search for "reshade rtgi 0361" speaks to a desire for more graphical power, for the ability to see older games in a new light. Whether you are revisiting a classic like Portal 2 or pushing a modern title like Stellar Blade to its limits, this specific version of the RTGI shader is a powerful, accessible, and time-tested tool.
