Ray Tracing Shader Rtgi 0.33 — Reshade

If the world looks inverted or broken when you turn on depth-based shaders, go to the tab or edit global preprocessor definitions to toggle settings like RESHADE_DEPTH_IS_REVERSED . Optimizing RTGI 0.33 Settings for Performance and Visuals

Because RTGI 0.33 is a "deep" shader that essentially recalculates light for the entire screen, it is very demanding. You will likely see: 0;16;

While RT cores are not mandatory, ray tracing is demanding. An NVIDIA GTX 1080 Ti / RTX 2060 or AMD RX 5700 XT is recommended for stable 60 FPS gameplay at 1080p. Reshade Ray Tracing shader RTGI 0.33

Visual impact

: Usually caused by a "temporal" setting in the game (like TAA). Try disabling the game's native Anti-Aliasing.

: While RTGI supports various APIs, newer versions (including 0.33) have dropped official DX9 support; a Vulkan wrapper is recommended for older DX9 titles. If the world looks inverted or broken when

Released around August 2022, version 0.33 introduced several significant technical improvements: Motion Vectors Integration

Unlike a basic photo filter, RTGI 0.33 gives you deep control over the lighting physics. Users can adjust the "Number of Rays" (quality vs. performance), ray length, and intensity of specular and diffuse light.

When a ray hits an object in the depth map, it samples the color of that pixel. An NVIDIA GTX 1080 Ti / RTX 2060

| Setting | Low Impact (60 FPS) | High Quality (30 FPS) | Explanation | | :--- | :--- | :--- | :--- | | | 0.10 - 0.15 | 0.25 - 0.40 | How far light bounces. Longer = more bounce, but more noise. | | Ray Count | 2 - 3 | 6 - 8 | The killer setting. Keep at 2 for 1080p. Raise to 4 for 1440p. | | Bounces | 1 | 2 | Secondary bounces. For 0.33, stick to 1 unless on a 4090. | | TAA Strength | 0.85 | 0.70 | Higher TAA reduces flicker but adds ghosting. 0.85 is safe. | | Intensity | 1.0 | 1.5 | General brightness of the bounced light. |

Launch the game and press the key to open the ReShade overlay. Navigate to the Add-ons tab.

Since the RTGI shader is technically "Pay What You Want" on Patreon, the installation process is manual. Here is a step-by-step walkthrough for the RTGI 0.33 version.

The , developed by Pascal Gilcher (also known as Marty McFly), is a sophisticated post-processing effect that simulates realistic lighting and shadows in games that do not natively support ray tracing. What is RTGI 0.33?

While RTGI 0.33 is a technical marvel, it is bound by the laws of screen-space processing:
