The biggest enemy of screenspace ray tracing is visual noise and fizzing artifacts. Because RTGI casts a limited number of rays to keep frame rates playable, the resulting image can look grainy. RTGI 0.33 introduces a highly advanced temporal filter. It blends current frames with past frames more accurately, smoothing out noise without causing distracting ghosting artifacts behind moving objects. 2. Infinite Bounces Simulation
: Activating full RTGI (Diffuse and Specular) can impact frame rates significantly, sometimes halving them depending on the game and hardware.
: Unlike "true" hardware-based ray tracing, this shader operates on depth buffer information . This means it can only "trace" what is currently visible on your screen, acting as a highly advanced form of ambient occlusion. reshade ray tracing shader rtgi 033
is a significant update to the Ray Traced Global Illumination (RTGI) shader developed by Pascal Gilcher (also known as Marty McFly). This post-processing shader approximates real-time ray tracing effects in almost any game that supports ReShade. Key Features of RTGI 0.33
What if you could bring cinematic, path-traced ambient occlusion and indirect lighting to decades-old classics, indie games, or even your favorite competitive shooters? Enter the . The biggest enemy of screenspace ray tracing is
Performance Tip: Set this to . The built-in denoiser is powerful enough to clean up the image, saving you up to 20% performance compared to "High."
Works seamlessly across DirectX 9, DirectX 11, DirectX 12, and Vulkan. It blends current frames with past frames more
Path tracing is inherently noisy. RTGI 0.33 features an advanced spatial-temporal denoiser.
Reduced GPU overhead, making ray tracing playable on mid-range graphics cards.
Select the appropriate rendering API (usually DirectX 11 or 12 for modern games).
Reshade’s RTGI 0.33 (Ray-Traced Global Illumination) is a community shader that simulates real-time global illumination inside Reshade by tracing rays in screen-space and reconstructing indirect lighting. It’s widely used to boost scene depth, color bleeding, and realistic indirect illumination in unsupported engines without native ray tracing. This post summarizes what RTGI 0.33 does, how it works, installation and setup, configuration tips, common trade-offs, and troubleshooting.
