Shader Rtgi 0.33 !!install!!: Reshade Ray Tracing

The shader by Pascal Gilcher (Marty McFly) is a post-processing tool for ReShade that simulates path-traced lighting, shadows, and ambient occlusion in almost any DX9, DX11, DX12, or Vulkan game.

You cannot just toggle RTGI 0.33 on and expect miracles. The default settings are usually too aggressive. Use this tuning matrix for 60 FPS gameplay on an RTX 3060 / RX 5700 XT. Reshade Ray Tracing shader RTGI 0.33

In simple terms: Light bounces. In vanilla Skyrim, a red brick wall casts a grey shadow. In RTGI, that shadow turns slightly red because the light bounces off the wall onto the floor. This bounce lighting creates depth, realism, and atmosphere that traditional rasterization simply cannot replicate. The shader by Pascal Gilcher (Marty McFly) is

Simulates how light bounces off surfaces to illuminate dark corners naturally. Ambient Occlusion: Provides deep, accurate contact shadows where objects meet. Infinite Bounces: Use this tuning matrix for 60 FPS gameplay

What changed in 0.33

refines that core idea with better temporal stability, reduced edge artifacts, and a smarter sampling pattern.
