: It provides "micro-shadows" where objects meet the ground, preventing the "floating" look common in games with poor ambient occlusion.
: If a character stands next to a bright red wall, their clothing will subtly pick up a red tint, mimicking the physical behavior of light in the real world. Performance vs. Visual Fidelity ReShade 5.3 and RTGI 0.33 Update | August 2022
Even as newer versions have been released, RTGI 0.33 represents a perfect snapshot of where real-time ray tracing through mods stood. It democratized high-end lighting effects, bringing them to gamers without the need for the latest flagship graphics cards. Reshade Ray Tracing shader RTGI 0.33
Version 0.33 was a significant release in the shader's timeline. While specific patch notes for this exact version (0.33) are a bit scarce, it is widely referenced as a stable and popular build within the community. Many ReShade preset creators explicitly state their compatibility with RTGI 0.33 or newer, cementing it as a reliable standard for a considerable period.
In version 0.33, the RTGI shader pairs with the , which utilizes an optical flow algorithm to generate motion vectors. This dramatically reduces the visual noise and flickering that plagued earlier versions, resulting in much smoother lighting transitions during fast movement. 2. Improved Bounce Light Accuracy : It provides "micro-shadows" where objects meet the
So, what makes RTGI 0.33 so special? Here are some of its key features:
Whether you are a modder looking for the perfect base for a preset or a gamer wanting to breathe new life into an old favorite, RTGI 0.33 is the gold standard for post-processing ray tracing. All it takes is a five-dollar pledge to the developer, an hour of tinkering with the sliders, and you will be looking at your games in a completely new light—literally. Visual Fidelity ReShade 5
RTGI 0.33 is a "Screen Space" ray tracing shader. Unlike native hardware-accelerated ray tracing, which calculates light rays interacting with every triangle in a 3D scene, RTGI uses the game’s and color information to "ray march" across the screen.
It requires placing the quint motion vectors.fx file (found in the Marty McFly Patreon Discord) properly within the ReShade shader list, typically above the main RTGI shader. 2. Improved Image-Based Lighting (IBL)
