For decades, Global Illumination (GI) has been the "holy grail" of real-time rendering. While rasterization techniques have improved significantly, they struggle to accurately simulate light bouncing (radiosity), often resulting in flat lighting or unrealistic shadows in areas not directly hit by a light source.

With the release of version 0.36.1, the RTGI shader by Pascal Gilcher represents one of the most sophisticated implementations of ray tracing available as a post-process effect. Unlike NVIDIA’s RTX, which utilizes dedicated hardware cores (RT cores) for BVH (Bounding Volume Hierarchy) traversal, ReShade RTGI operates entirely in screen space, making it compatible with a wider range of DirectX 9, 10, and 11 titles.

In the world of real-time post-processing shaders, few names carry as much weight as Pascal "Marty McFly" Gilcher and his RTGI shader. While newer versions have moved to a paid early-access model on Patreon, version 0.36.1 remains a landmark release—the final free, fully public version before the project pivoted. For many gamers and virtual photographers, this build represents the peak of what’s achievable with screen-space ray tracing in older or stylized games. Upgrade to the paid version if: For decades,
