Reshade Ray Tracing Shader Rtgi 033 Jun 2026

Many users confuse “RTGI” with the free shaders included in the default ReShade effect package. The standard ReShade installer does contain RTGI. To use RTGI, you must:

So, what makes RTGI 0.3.3 so special? Here are some of its key features:

RTGI, or Real-Time Global Illumination, is a technique that simulates the way light interacts with its environment, taking into account the complex interplay of reflections, refractions, and diffusions. This effect is particularly challenging to achieve in real-time, as it requires the simulation of light transport across an entire scene. The ReShade Ray Tracing Shader RTGI 0.3.3 brings this technology to the masses, enabling users to experience stunning, cinema-quality visuals in a wide range of applications. reshade ray tracing shader rtgi 033

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.

Version 0.33 was a landmark update that introduced major architectural changes to how lighting is calculated: Many users confuse “RTGI” with the free shaders

is a remarkable piece of graphics programming that democratized global illumination for thousands of older games. While it suffers from screen-space artifacts and a noticeable performance hit, it remains a popular choice for modders and gamers seeking to enhance lighting in titles never designed for ray tracing. Its legacy is that of a bridge technology – between classic rasterization and full hardware ray tracing – that proved the visual value of GI before it became mainstream.

Set to Medium . Setting this to "Very High" doubles the performance cost for negligible visual gain, as the temporal filter handles the rest. Here are some of its key features: RTGI,

Launch your game and press or Pos1 to open the ReShade overlay. Go to the Add-ons tab.

Once the shader is active, you can customize the parameters in the lower panel of the ReShade menu:

RTGI 0.33 is the best alternative for GPUs that lack RT cores. It turns flat, old games into moody, volumetric masterpieces.
