Reshade Ray Tracing Shader Rtgi 0.33 [top] Jun 2026

Download the standard standard effect packages when prompted (Standard, SweetFX, and Quint are highly recommended). 2. Add the RTGI 0.33 Files Extract the downloaded RTGI 0.33 zip file. Locate the Shaders and Textures folders within the zip.

The game engine tracks light rays across the entire virtual world, including objects behind the player or hidden around corners. This requires massive hardware computational power and direct engine integration.

If that pixel is bright or highly saturated, the shader projects that color and light back onto surrounding pixels, creating realistic ambient lighting. Performance Impact: What to Expect

But what makes version 0.33 so special? Is it actually "ray tracing"? And how can you install it without frying your GPU? This article dives deep into the technical nuances, performance impact, and the best games to resurrect using this shader. Reshade Ray Tracing shader RTGI 0.33

What changed in 0.33

| Setting | Low Impact (60 FPS) | High Quality (30 FPS) | Explanation | | :--- | :--- | :--- | :--- | | | 0.10 - 0.15 | 0.25 - 0.40 | How far light bounces. Longer = more bounce, but more noise. | | Ray Count | 2 - 3 | 6 - 8 | The killer setting. Keep at 2 for 1080p. Raise to 4 for 1440p. | | Bounces | 1 | 2 | Secondary bounces. For 0.33, stick to 1 unless on a 4090. | | TAA Strength | 0.85 | 0.70 | Higher TAA reduces flicker but adds ghosting. 0.85 is safe. | | Intensity | 1.0 | 1.5 | General brightness of the bounced light. |

Go to the preprocessor definitions and look for RTGI_RENDER_SCALE . Setting this to 0.5 or 0.7 renders the ray tracing at a lower resolution while keeping your game crisp. Version 0.33's denoiser will upscale the lighting seamlessly.

After installing, launch the game. Press the key to open the ReShade overlay.

Early versions of screen-space illumination suffered from "one-and-done" lighting, where light hit a surface and stopped. RTGI 0.33 features highly optimized multi-bounce approximations. When bright sunlight hits a red brick wall, the red light accurately bounces onto the concrete pavement, which then subtly reflects onto nearby objects. 2.

Copy the accompanying texture files into reshade-shaders\Textures . Step 3: Configure the Depth Buffer

: Use RTGI alongside in-game DLSS, FSR, or XeSS to recoup lost performance. Limitations of Screen-Space Ray Tracing

is a generic post-processing injector. It can add SMAA anti-aliasing or color filters to virtually any DirectX 9/10/11/12 or Vulkan game.

: It provides "micro-shadows" where objects meet the ground, preventing the "floating" look common in games with poor ambient occlusion.
