Reshade Ray Tracing Shader Rtgi 033 2021 -

If you are looking to install this today, ensure you are using the latest version of ReShade along with the updated RTGI available through Marty McFly's Patreon.

The RTGI (Real-Time Global Illumination) shader, version 0.3.3, developed for use with Reshade, represents a significant advancement in real-time lighting technology for games and interactive applications. Released in 2021, this shader leverages the power of ray tracing, a rendering technique that accurately simulates the way light behaves in the real world, creating more immersive and visually stunning experiences.

While newer versions of RTGI have since been released, the is remembered as a stable, high-quality baseline. It proved that global illumination is the single most important factor in achieving photorealism in real-time rendering. For many PC gamers, applying RTGI v0.33 to a favorite classic title was the moment the game truly felt "next-gen." reshade ray tracing shader rtgi 033 2021

Unlike 2023’s RTGI 1.0 (which required a paid Patreon sub for early access), on GitHub and community forums, cementing its legacy.

The 0.33 version released in 2021 remains a favorite package for retro gaming enthusiasts and modders. It struck a perfect balance before later versions increased complexity with features like Regard3D and complex motion vectors. For titles like The Witcher 3 (classic version), Skyrim , Batman: Arkham Knight , and Dark Souls , RTGI 0.33 acts as a definitive remaster mod, breathing vibrant new life into aging virtual worlds.

Unlike native ray tracing solutions from Nvidia (RTX) or AMD (RX), RTGI 0.33 does not rely on hardware-level BVH (Bounding Volume Hierarchy) traversal. It executes entirely through standard compute shaders. This means you can run ray-traced global illumination on older graphics cards, including the Nvidia GTX 10-series or older AMD Radeon cards.

Because RTGI 0.33 processes ray tracing via software shaders, it does not strictly require Nvidia RTX or AMD RX hardware cores. It runs on almost any modern GPU.

The RTGI_033 team's achievement marked a significant milestone in the evolution of real-time graphics. Their work had not only pushed the boundaries of what was thought possible but had also democratized access to advanced graphics techniques. The shader became a benchmark for future developments, inspiring others to explore the vast possibilities of ray tracing and global illumination.

Note: RTGI does not work with all anti-cheats (EAC, BattlEye). Do not attempt in online multiplayer games.
