The ReShade Ray Tracing Shader RTGI 0.33 Exclusive remains a landmark achievement for graphics enthusiasts. By focusing on stability and advanced motion handling, it helped set the standard for what is possible in post-processing ray tracing. While newer versions exist, 0.33 is a testament to the rapid innovation in computer graphics modding, allowing gamers to experience the future of lighting in their favorite classics. *If you'd like, I can:

To understand the significance of RTGI v0.33, one must understand how it differs from native ray tracing. Modern games that support ray tracing (like Cyberpunk 2077 or Control ) utilize hardware-accelerated rays cast from the GPU's RT cores, calculating physics-accurate light paths in a 3D world space. In contrast, ReShade operates in "screen space." It does not have access to the game's full 3D geometry; it only sees what the player sees on the screen (the depth buffer and color texture).
The development of a (codenamed “Fulcrum”) is also underway, promising to overcome the limitations of screen‑space techniques and deliver full scene‑level ray tracing to virtually any game—similar in ambition to Nvidia’s RTX Remix but without vendor lock‑in.

Even as newer, faster, and more feature‑rich versions of RTGI have appeared, version remains a touchstone for the community. It represents a moment in time when the shader had matured enough to be widely adopted but before the more complex features of later versions introduced additional overhead.

A: At the time of its release, v0.33 was exclusive to Patreon. That is the source of the nickname. While newer versions (0.36, 0.40, etc.) are now available, the "v0.33" files themselves are still locked behind the Patreon paywall, retaining their exclusivity.
