The path forward is even more exciting. Gilcher’s ongoing work on HiZ tracing, gradient‑descent sampling, and eventual split of diffuse/specular shaders promises even higher fidelity and greater customisation. Yet the core concept remains as compelling as ever: light bounces, and with RTGI, so can your games .
While it is less demanding than native DXR, RTGI is still heavy. An NVIDIA GTX 1070 / AMD RX 580 is the bare minimum for 1080p, while an RTX 2060 or RX 6600 is recommended for stable frame rates.
Ultimately, is not just a shader; it is a time capsule of PC gaming ingenuity. It proved, long before NVIDIA marketed Path Tracing, that ray tracing was possible on standard raster hardware if you were clever enough. Fire up Skyrim , toggle that checkbox, and watch the gray dungeons finally glow with warm, bounced torchlight. That is the magic of version 0.33. reshade ray tracing shader rtgi 033
When DisplayDepth is active, you should see the left half of the screen in a colourful, heat‑map style, and the right half in greyscale. If you see this, the depth buffer is already correctly detected. If the screen is or shows only colours/greyscale on the wrong side , proceed to the next step.
Blends historical frames to eliminate shimmering. Raise this if the lighting flickers when you move the camera. Performance Optimization Tips The path forward is even more exciting
(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.
and normal maps to calculate how light should bounce around the scene. Diffuse Global Illumination While it is less demanding than native DXR,

Version 0.33 isn’t a revolutionary rewrite—it’s a refinement of the shader that first dropped in 2020. But those refinements matter.
