While RTGI does not strictly require hardware RT cores (like NVIDIA RTX or AMD RX 6000+), a mid-to-high-end GPU (GTX 1080 Ti / RTX 3060 / RX 5700 XT or better) is recommended for stable frame rates.
Version 0.33 specifically focuses on refining the ray-marching algorithms. It reduces the "noise" and fuzziness common in older versions while significantly lowering the performance cost on modern GPUs. Key Features of the 0.33 Update 1. Advanced Infinite Bounces (Approximated) Reshade Ray Tracing shader RTGI 0.33
This is invisible but massive. The shader now better detects edges between far and near geometry, reducing that classic “light leak” around door frames and character shoulders. Not gone entirely (impossible in screen space), but much better.
Whether you are remastering an old classic like Skyrim or enhancing the atmosphere of a modern title, RTGI 0.33 remains one of the most powerful visual tools in a PC gamer's arsenal. To help customize this for your specific setup, tell me: What are you trying to configure RTGI 0.33 for? What graphics card (GPU) are you running? Copy qquint_rtgi
: Instead of light just hitting a floor and stopping, RTGI allows that light to reflect back up onto the ceiling and walls, filling shadows with color and warmth.
Ray tracing, even when emulated through ReShade, is highly demanding: It reduces the "noise" and fuzziness common in
: Like its predecessors, RTGI 0.33 functions by "scraping" a game's depth buffer to understand the 3D structure of a scene. It then shoots virtual rays within that space to calculate how light should bounce off surfaces.
⚠️ Note: While it works on many cards, ray tracing is inherently demanding. As Marty McFly puts it, using it on "a toaster" is not recommended.
