Perhaps the most important feature of RTGI is its democratizing effect. While hardware-based ray tracing is often gated behind the latest and most expensive NVIDIA RTX or AMD Radeon RX 6000-series cards, RTGI 0.36.1 is . By performing software-based ray and path tracing solely on depth data, the shader bypasses the need for specialized hardware. This means that owners of older GPUs, such as the NVIDIA GTX 1080 or AMD Radeon 5700, can finally experience the visual benefits of ray-traced global illumination, provided their cards have enough raw compute power to handle the processing load. Of course, a very low-end "toaster" will still struggle, but for the vast majority of PC gamers with a dedicated GPU from the last 6-7 years, RTGI is an accessible technology.
It is important to note that this is not "true" hardware ray tracing. Since it is a post-processing effect, it only calculates lighting for what is currently visible on your screen; objects behind the camera or off-screen will not cast reflections or light. Setup and Optimization
To get RTGI 0.36.1 working correctly, you need to ensure your depth buffer Reshade Rtgi 0.36.1
Download the standard SweetFX or Quint shader packs when asked. Step 2: Inject the RTGI 0.36.1 Shaders
Tells the shader how "thick" 3D objects are, since screen-space data doesn't know what is behind an object. Adjust this if you notice strange dark halos or light leaks behind thin objects like tree branches or poles. 4. Enable Denoising Filter Perhaps the most important feature of RTGI is
: The shader uses the game's depth map to determine the physical distance of objects. Diffuse Global Illumination
ReShade is a generic post-processing injector for games and video software. It allows users to overlay advanced color correction, sharpening, and ambient occlusion filters onto a game. This means that owners of older GPUs, such
Paste them into your game directory's reshade-shaders folder, overwriting any existing files. Step 4: Configure the Depth Buffer Launch the game and press Home to open the ReShade overlay.
Because RTGI only knows what is on screen, objects hidden behind your character or just off-camera will not cast ray-traced shadows or light. System Requirements While lighter than native DXR, RTGI 0.36.1 is demanding.
