So, why should you use RTGI 0.3.3? Here are some benefits:

(e.g., RTXGI, DXR) uses the actual 3D geometry of the scene, stored in acceleration structures like bounding volume hierarchies (BVH). It can produce physically accurate illumination, shadows, and reflections, and it typically leverages dedicated RT cores in modern GPUs to accelerate BVH traversal. reshade ray tracing shader rtgi 033

One of the most appreciated changes in 0.33 was a reduction in overhead compared to earlier beta releases. The shader became more efficient in how it sampled rays, allowing it to run at usable frame rates on mid‑range GPUs. According to testing, even integrated graphics and older mobile GPUs can run RTGI if the internal resolution is lowered sufficiently.

ReShade is a free, open-source post-processing injector that allows users to enhance the visual quality of their games and applications. Developed by Boris Vorontsov, ReShade has become a staple in the gaming community, offering a wide range of shaders that can be used to improve graphics, add new effects, and even enable features like ray tracing.

The fundamental technology behind RTGI, the core improvements introduced in version 0.33, and the exact steps to configure it for optimal PC gaming performance are outlined below. Understanding ReShade RTGI Shaders

Once this reconstruction is built, RTGI 0.33 performs a "path tracing" simulation on this screen-space data. Because it has no access to geometry outside your current field of view, RTGI must make intelligent estimates for occluded areas and surfaces that are hidden from the camera. While this approach has limitations, Gilcher's algorithm used a proprietary method distinct from the earlier, more popular ReSTIR GI technique, aiming to maintain high visual fidelity even while relying on limited data. By version 0.33, the technology had proven itself capable of generating temporally stable lighting, minimizing the distracting flickering that often plagued other screen-space solutions.

ReShade’s RTGI shader has been updated to version 0.33, and the jump in visual fidelity is insane. Pascal Gilcher has outdone himself this time.

The improvements to temporal stability are a game-changer—no more shimmering while moving the camera. The lighting feels so much more natural and grounded now. It’s crazy what a shader can do for immersion in games that are years old.
