For years, the holy grail of PC gaming graphics has been Ray Tracing. For most gamers, native hardware-accelerated ray tracing (via NVIDIA RTX or AMD Radeon RX) remains a premium feature locked behind expensive GPUs and a limited library of supported AAA titles.
Crucial: Use the "Full Add-on Support" version if playing single-player games to ensure depth buffer access. Deploy RTGI Files: Open your game's installation folder (where the .exe is). Locate the reshade-shaders folder. reshade ray tracing shader rtgi 033
Download: Get ReShade + qUINT from the official forums.

While ReShade has long been used for post-processing effects like bloom, HDR, or ambient occlusion (SSAO), RTGI v0.33 is distinct because it is a screen-space ray tracing solution. It relies on the existing depth buffer and color information from the game to calculate bounces. Lower values reduce cost and limit bleeding range;
ReShade is a popular, open-source post-processing injector that allows users to enhance the visual fidelity of their favorite games and applications. Developed by Boris Vorontsov, ReShade provides a flexible framework for injecting custom shaders into a wide range of titles, enabling users to apply various graphical effects, from simple tweaks to complex, compute-intensive transformations.
RTGI stands for Ray Traced Global Illumination. In traditional game rendering (rasterization), lighting is often "baked" into the textures or simulated via pre-placed light sources that don't naturally bounce. A light source illuminates a wall, but the light doesn't bounce off that wall to illuminate the floor.
RTGI v0.33 isn’t the future of real-time rendering—it’s a clever hack from a brilliant modder (Marty McFly) who refused to wait for game devs to catch up. In the right game, on the right hardware, it feels like magic. In the wrong game, it’s a performance-killing noise machine.
