The 0.33 iteration focused on improving the quality of light bounces and the efficiency of the ray casting process. 1. Improved Performance & Ray Tracing Efficiency
Traditional games use pre-baked lighting or simple ambient occlusion techniques (like SSAO or HBAO) that look flat. RTGI completely changes the scene dynamics.
Launch the game, open the ReShade overlay ( Home key), navigate to the "Add-ons" tab, and ensure the correct depth buffer is selected. Turn off in-game Anti-Aliasing (MSAA) if the depth buffer appears blank. Limitations of Screen-Space Ray Tracing
Enable the DisplayDepth shader. Your screen should show a clear grey/white depth map. If it’s solid black or flickering, RTGI will not work.
High temporal denoising values can cause a trailing effect behind moving objects. reshade ray tracing shader rtgi 033 2021
| Feature | Specification | |---------|----------------| | | SM 5.0+ | | Ray Tracing Method | Hierarchical screen-space ray marching (Hi-Z) | | Input Buffers | Color, Depth, Normal (ReShade depth buffer, reconstructed normals) | | Bounces | 1 indirect bounce (simulated) | | Ray Count per Pixel | Variable: 2–6 (performance vs. quality) | | Denoiser | Spatiotemporal (bilateral + temporal accumulation) | | API Support | DirectX 9–12, OpenGL, Vulkan (via ReShade bridge) |

For those who may be unfamiliar, ReShade is a popular, open-source post-processing injector that allows users to enhance the visual quality of games and other graphics applications. It works by injecting custom shaders into the rendering pipeline, enabling features like anti-aliasing, depth of field, and motion blur. ReShade has become a go-to tool for gamers and developers looking to improve the visual fidelity of their games and applications. RTGI completely changes the scene dynamics
So, what makes ReShade Ray Tracing Shader RTGI 0.3.3 so special? Here are some of its key features and enhancements:
Launch the game and press the key to open the ReShade overlay. Navigate to the DX11/DX12/Vulkan tab at the top.
Ensure ReShade has access to your game’s depth buffer (disable MSAA in-game).
This article explores the , its impact in 2021, why it became a cornerstone of modern reshading, and how it brought true ray-traced lighting to almost any game. What is ReShade RTGI 0.3.3? more stable lighting over time
, where a subscription (typically at the $5 tier) grants access to the latest beta versions and the community Discord. Reshade RTGI vs 'real' Ray-Traced GI 20 Aug 2021 —
The performance impact of the ReShade Ray Tracing Shader RTGI 0.3.3 varies significantly depending on the game, system specifications, and chosen settings. For less powerful hardware, enabling ray tracing can result in a considerable frame rate drop. However, for systems equipped with capable GPUs that support ray tracing (such as NVIDIA RTX series or AMD Radeon RX 6000 series and later), the performance hit can be managed with the right settings.
Earlier versions often suffered from "noisy" lighting that fluctuated between frames. RTGI 0.33 improved temporal accumulation, creating smoother, more stable lighting over time, reducing the need for heavy denoising, which can blur the image. Setting Up RTGI 0.33 in 2021 (and Beyond)
