: Controls how much "glow" the bounced light produces. Comparison to Native Ray Tracing
This mechanism samples the game’s overall on-screen color spectrum to simulate realistic ambient sky lighting. This prevents areas from turning into pitch-black voids when direct lighting isn't present. 2. Key Graphical Improvements Offered by RTGI 0.33
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 reshade ray tracing shader rtgi 033
Always leave this enabled. Turning it off will result in a grainy, pixelated mess. Common Troubleshooting Steps Light Bleeding Through Walls
: It physically simulates light bouncing off surfaces, allowing sunlight to illuminate dark corners or "bleed" colors from one object onto another. Ambient Occlusion : Controls how much "glow" the bounced light produces
Performance Tip: Set this to for a massive performance boost. Combined with the spatial denoiser, the visual degradation is minimal while your FPS sky-rockets.
So, what made version 033 so special, and what are the general hallmarks of the RTGI technology? Let's break it down: RTGI 0
Go to the "DX11/DX12/Vulkan" tab in ReShade and ensure the correct depth buffer is checked. If your depth buffer is inverted or broken, look for the Edit Global Preprocessor Definitions button on the Home tab and toggle RESHADE_DEPTH_IS_REVERSED between 0 and 1.
If you cannot find v0.33 anywhere, note that the modern successor ( ) is available on Pascal Gilcher's Patreon for $5, though the algorithm has changed significantly. For the classic "0.33 look," you must find a community archive.
: RTGI is a premium shader. You must subscribe to the Pascal Gilcher Patreon (typically the "Beta" or "Alpha" tiers) to gain access to the download links, often provided via a Discord server.
: In standard games, "ambient" light is often a flat value. RTGI allows light to pick up colors from surfaces—for example, a red wall will cast a subtle red glow onto a white floor nearby. Realistic Ambient Occlusion
