Reshade Ray Tracing Shader Rtgi 033 Free

Step 1: Install ReShade Run the ReShade installer. Click "Select game" and locate your game's .exe file. Select the rendering API (usually DirectX 10/11/12). When asked to download a standard shader pack, say "Yes" – this gets you the basic effects.

Step 2: Locate the Shaders Folder After installation, go to your game’s root directory. You will find a folder named reshade-shaders. Inside that, open the Shaders folder.

Step 3: Manually Add RTGI 0.33 Download the RTGI.fx (and any .fxh helper files) for version 0.33. Copy these files directly into the reshade-shaders/Shaders folder.

Step 4: Launch and Configure Start your game. You should see a ReShade tutorial pop-up (press the Home key by default). Open the ReShade overlay. Go to the "Settings" tab.

Step 5: Enable RTGI Navigate to the "Home" tab. In the search bar, type "RTGI". You will see the shader appear. Click the checkbox next to it. If done correctly, your screen will suddenly look darker, with rich bounce lighting.

Pro-tip: Disable the game’s native Ambient Occlusion (SSAO/HBAO). RTGI replaces it and will conflict, causing double-dark shadows.

Problem: "RTGI is greyed out / says 'Failed to compile.'" Solution: You are missing the ReShade.fxh file or using an outdated ReShade version. Download ReShade 5.0 or newer. Step 1: Install ReShade Run the ReShade installer

Problem: The effect flickers or looks like "soup." Solution: Screen-space ray tracing requires a depth buffer. Go to the ReShade "Add-ons" tab and ensure "Copy depth buffer before clear" is checked. Also, disable anti-aliasing in-game (use ReShade's SMAA instead).

Problem: "My FPS dropped from 100 to 20." Solution: You likely turned on "Bounce Count: 2" or set "Ray Length" to 5.0. Reset to the recommended settings above. Also, lower your resolution scale.

Problem: The lighting looks "blocky" or has pixelated artifacts. Solution: Increase "Quality" to High or Ultra, but understand that this uses more VRAM. Alternatively, enable the "Temporal Anti-Aliasing" (TAA) shader included with ReShade. When asked to download a standard shader pack,

Developed by the brilliant Pascal "Marty McFly" Gilcher, the RTGI shader simulates how light bounces off surfaces in real-time. Unlike traditional ambient occlusion (which only adds shadows in corners), RTGI calculates the intensity of incoming light and its color bleed. For example, a red brick wall will cast a faint red tint onto a white floor nearby.

The version number 0.33 holds a special place in the modding community. Why?
