If you have a modern GPU and a library of older games begging for a next-gen remaster, RTGI 0.33 is an absolute essential.
Prior versions of RTGI were highly susceptible to "shimmering" or aggressive visual noise when the camera moved quickly. Version 0.33 specifically resolved these historical pain points through two core features:
Ray-Traced Global Illumination (RTGI) simulates how light bounces off surfaces to illuminate areas not directly hit by a primary light source. reshade ray tracing shader rtgi 033
| Setting | Recommended Value | Why | | :--- | :--- | :--- | | | High (or Ultra if GPU allows) | Lower quality causes "boiling" noise in shadows. | | Ray Length | 0.8 – 1.5 | Higher values = light bounces further (but can wash out dark areas). | | Intensity | 0.4 – 0.7 | Global brightness of bounced light. Start low. | | AO Strength | 0.5 – 1.0 | Adds contact shadows where objects meet. | | Bounce Count | 1 or 2 | 2 bounces looks more natural but costs ~20% performance. | | Enable Denoiser | ON | Removes grain. Essential. | | Denoiser Radius | 0.5 | Lower = sharper but noisier. Higher = smoother but softer. | | Half Res | OFF | Keep OFF . Turning this on destroys image quality. |
First impressions: The noise reduction is noticeably better compared to the previous builds. I’m seeing much cleaner edges in high-contrast scenes, and the performance cost feels slightly lower on my setup (running a [Insert Your GPU Model here]). If you have a modern GPU and a
You will need the latest version of ReShade installed to your target game's executable directory. How to Install and Set Up RTGI 0.33
The ReShade Ray Tracing Shader RTGI 0.3.3 boasts an impressive array of features, including: | Setting | Recommended Value | Why |
: RTGI is primarily distributed through Pascal Gilcher’s Patreon , where it remains a "early access" or "beta" feature for supporters.
Because RTGI 0.33 relies on the depth buffer and complex mathematical calculations, it requires a capable PC.
ReShade is a generic post-processing injector for games and video software. It intercepts data at the compiler level to apply new visual effects. is a premium shader developed by Pascal Gilcher (known online as Marty McFly).
