The shader, developed by Pascal Gilcher (widely known as Marty McFly ), is a major update that brings real-time, screen-space ray-traced global illumination to older and modern PC games. By physically simulating how light reflects off in-game surfaces, it bridges the gap between traditional rasterized lighting and true hardware ray tracing.
Technical approach (concise)
As of 2026, how does an old shader stack up against modern tech?
Are you aiming for or photo-mode visuals ? Reshade Ray Tracing shader RTGI 0.33
Ray tracing benefits from consistent frame delivery. Cap your frame rate to a stable 45 or 60 FPS using RivaTuner Statistics Server (RTSS) to eliminate micro-stuttering. Conclusion
RTGI 0.33 enhances how light bounces off surfaces, particularly in bright scenes. When combined with image-based lighting, the shader produces more accurate color bleeding (e.g., a blue wall reflecting blue light onto a white floor). 3. Better Temporal Stability
Copy the RTGI folder (containing textures/headers) into the Textures subfolder. : Press Home to open the ReShade overlay. 3. Configuring the Depth Buffer The shader, developed by Pascal Gilcher (widely known
: Better differentiation between rough surfaces and metallic sheen.
: A feature in newer versions that allows light to bounce multiple times, creating much more realistic interior lighting.
A: YES. Do not use Reshade (any version) in Call of Duty , Valorant , or Destiny 2 . Their anti-cheat software flags depth buffer access as a wallhack. Single-player games only. Are you aiming for or photo-mode visuals
Copy the files from the Shaders and Textures folders into your game's reshade-shaders directory.
Ray tracing inherently produces "noise" or graininess. RTGI 0.33 introduces an updated temporal denoiser that blends past frames with the current frame more intelligently. This reduces shimmering and ghosting behind moving objects.
