The centerpiece of update 0.36.1 is Gilcher's decision to abandon a widely respected industry algorithm in favor of his own creation. Originally, he tried to implement NVIDIA's ReSTIR GI algorithm into his shader, but he encountered significant and persistent issues. These included "chroma noise" (because the reservoir sampling method could only hold light from a single direction), sample correlation problems that broke the denoiser's variance estimation, and an unstable white noise output.
Before diving in, ensure your system and game are ready to handle the shader. System Requirements
When prompted, choose the version with full add-on support . This is mandatory for ReShade to access the depth buffer in multiplayer or protected games.
Visit the official ReShade website to download the latest setup tool. Run the installer, click "Browse," and select your game’s executable (e.g., Cyberpunk2077.exe or SkyrimSE.exe ). Choose the correct rendering API for your game (typically DirectX 10/11/12 or Vulkan). Reshade Rtgi 0.36.1
Compared to earlier versions like 0.17 or 0.25, 0.36.1 offers vastly improved sampling accuracy and reduced "flickering" in high-contrast scenes.
: The shader uses the game's depth map to determine the physical distance of objects. Diffuse Global Illumination
: Because it operates on depth data rather than dedicated hardware cores, RTGI is compatible with non-RTX cards, though it remains "performance hungry" and should not be used on low-end systems. The centerpiece of update 0
By injecting screen-space ray tracing into almost any 3D game engine, this specific iteration refines stability, calculation accuracy, and performance to unleash true next-generation lighting in older and modern titles alike. Understanding ReShade RTGI
and global illumination to almost any 3D game. Unlike native implementations, it operates as a post-process effect by analyzing the game's depth buffer and frame color to simulate light bounces. 2. Core Methodology: Screen-Space Ray Tracing Depth-Based Simulation
: This version is noted for being "miles better" in terms of framerate stability compared to earlier iterations, making it more viable for gameplay rather than just screenshots. Before diving in, ensure your system and game
Reads the game’s 3D geometry directly to ensure shadows and light bounces align perfectly with objects. Hardware Requirements
: Tells the shader how "thick" objects in the screen-space are.
