ReShade RTGI (Ray Traced Global Illumination) shader, developed by Pascal Gilcher (also known as Marty McFly), is a post-processing tool designed to add realistic lighting effects to video games that do not natively support hardware-level ray tracing. marty's mods Key Features of RTGI 0.33 (2021-2022)
The 2021 0.33 beta release brought massive optimizations, cleaner denoising filters, and better compatibility with DirectX 11, DirectX 12, and Vulkan titles. Key Features of the 2021 0.33 Release : Unlike native NVIDIA RTX or AMD Ray
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.
While RTGI 0.33 delivers stunning results, users should keep its architectural limitations in mind: It works by injecting custom shaders into the
Unlike native hardware ray tracing (like Nvidia RTX or AMD DXR), ReShade RTGI is software-based. It runs on almost any graphics card that supports ReShade, but it is still highly demanding. Estimated Performance Impact Recommended RTGI 0.33 Settings (RTX 3070 / RX 6800 or better) 10% - 20% FPS Drop Ultra Quality, High Ray Count, Infinite Bounces On Mid-Range (RTX 2060 / RX 5700) 20% - 35% FPS Drop Medium Quality, 3-4 Ray Count, Denoising High Budget (GTX 1060 / RX 580) 40%+ FPS Drop Low Quality, Minimal Ray Steps, Presentation Mode Only Step-by-Step Installation Guide
Because RTGI runs entirely via software shaders, it stresses your raw GPU compute power rather than dedicated RT hardware.
: A significant addition in 0.33 was the integration of motion vectors, which drastically improved temporal stability, reducing the "shimmering" or ghosting artifacts common in earlier screen-space implementations.
In the rapidly evolving world of PC gaming graphics, 2021 marked a significant milestone for modding and visual enhancement. While NVIDIA was pushing RTX hardware-accelerated ray tracing, a revolutionary software-based solution was gaining traction: , with version 0.33 being a standout release that solidified the technology’s viability.
