Ray tracing inherently produces "noise" or graininess. RTGI 0.33 introduces an updated temporal denoiser that blends past frames with the current frame more intelligently. This reduces shimmering and ghosting behind moving objects.

While screen-space solutions are typically limited to a single light bounce, 0.33 utilizes an approximation algorithm to simulate multiple light bounces. This prevents dark corners from looking pitch black and creates a softer, more realistic distribution of light. Reshade Ray Tracing shader RTGI 0.33
Reuses lighting data from previous frames to smooth out noise. Set this higher to eliminate flickering, or lower if you notice ghosting during fast movements. Performance Troubleshooting
RTGI, by contrast, uses to simulate the behavior of light in the real world. It emits millions of rays, calculates where they bounce, and uses that data to fill in the "leftover" light that traditional methods miss. The result is dynamic, realistic lighting that was previously only possible in offline renderers. This gives players true, real-time global illumination injected into games that were never designed for it, creating far deeper shadows, clearer directional light, and richer color depth.
This essay explores the technical achievement and visual impact of the shader, specifically focusing on the advancements seen in version 0.33. The Evolution of Post-Process Lighting: ReShade RTGI 0.33 Ray tracing inherently produces "noise" or graininess
In the (Home tab), ensure:
RESHADE_DEPTH_INPUT_IS_REVERSED is set to 1 or 0 (try both until it looks right). RESHADE_DEPTH_INPUT_IS_UPSIDE_DOWN is usually 0 . 4. Tuning RTGI 0.33 Settings

For every pixel on your screen, RTGI shoots out virtual rays into this depth map.

If you want to tailor this setup for a specific game, let me know you are modding, your GPU model , and if you need help with UI masking or depth buffer alignment .
Launch the game and press the key to open the ReShade overlay. Go to the Add-ons tab.
Set between 8 and 12 . Higher numbers allow light rays to travel further across the screen, calculating large-scale environmental shadows.
