Keep this between 8 and 12 . Higher steps allow light to travel further across the screen but stress your GPU.

: It physically simulates light bouncing off surfaces, allowing sunlight to illuminate dark corners or "bleed" colors from one object onto another. Ambient Occlusion
Once activated, you will see 15+ sliders. Here is the optimal starting point for 1080p/1440p gaming. reshade ray tracing shader rtgi 033
RTGI also use RT cores or benefit from DLSS (Deep Learning Super Sampling). It is a pure compute shader that runs on general‑purpose GPU cores, which is why it remains compatible with older hardware.
Here is a comprehensive look at what ReShade RTGI 0.33 brings to the table, how it transforms your gaming library, and how you can configure it for the best balance of performance and visual fidelity. What is ReShade RTGI 0.33?
One of the most appreciated changes in 0.33 was a reduction in overhead compared to earlier beta releases. The shader became more efficient in how it sampled rays, allowing it to run at usable frame rates on mid‑range GPUs. According to testing, even integrated graphics and older mobile GPUs can run RTGI if the internal resolution is lowered sufficiently. Keep this between 8 and 12
RTGI allows you to render the ray tracing effect at half-resolution. Turning on half-resolution tracking provides a massive performance boost with minimal visual degradation, as the robust 0.33 denoiser upscales the lighting layer cleanly.
Running the shader at half-rate resolution drastically improves performance while the temporal filter keeps the lighting looking sharp.
RTGI 0.33 utilizes the game’s depth buffer to simulate how light bounces off surfaces, casts realistic shadows, and bleeds color onto adjacent objects. Version 0.33 represents a highly refined iteration of this shader, introducing advanced denoising algorithms, better temporal stability, and code optimizations that lower the performance penalty compared to older builds. Key Features of RTGI 0.33 1. True Global Illumination (GI) : It physically simulates light bouncing off surfaces,
The original RTGI shader is ; it is a paid product created by Pascal Gilcher and distributed through his Patreon page. Access to the shader files (including the specific 0.33 version) requires a $5‑per‑month “Raytracers” tier subscription.
When prompted, select standard shader packs like Standard Effects and SweetFX . Finish the installation.
Set to Medium . Setting this to "Very High" doubles the performance cost for negligible visual gain, as the temporal filter handles the rest.
