Set to 3 or 4 for gameplay. Reserve 7 or 8 strictly for taking high-fidelity screenshots.
: It simulates "Global Illumination," meaning light from a bright green wall will actually bounce off and cast a soft green hue onto nearby objects. How to Install RTGI 0.33
It is important to understand what RTGI is not . Unlike the ray tracing found in Cyberpunk 2077 or Metro Exodus , RTGI is a . It cannot see objects behind the camera or around corners. Consequently, light that should be cast by an object just outside the camera’s view may not render perfectly. Similarly, because it works in post-processing, RTGI often casts rays onto User Interface (UI) elements, causing "see-through UI" flickering during loading screens or gameplay.
If the depth screen is completely black or white, tweak the global preprocessor definitions: : Toggle between 0 and 1 . Reshade Ray Tracing shader RTGI 0.33
If you enjoy tinkering with visuals, replaying old favorites, or just want to see what “what if this game had bounce lighting?” looks like, .
Because RTGI 0.33 is a "beta" shader, it requires manual installation.
Select the correct rendering API (usually DirectX 11, DirectX 12, or Vulkan). Set to 3 or 4 for gameplay
How does a piece of software make your 2D screen look like a path-traced 3D world? It uses a few clever tricks of code.
RTGI is a "screen-space" solution. Unlike modern AAA games that use triangle-level ray tracing engines, RTGI analyzes the depth and color information of the pixels currently visible on your monitor (the depth buffer). It uses a sophisticated path-tracing algorithm to calculate how light would bounce between these pixels, adding ambient occlusion and color bleeding that wasn't there before.
So, what makes RTGI 0.33 so special? Here are some of its key features: How to Install RTGI 0
Version 0.33 refines this process by stabilizing the temporal filters. This update reduces the "ghosting" or trailing artifacts common in moving scenes while maximizing frame rates on mid-range graphics cards. Screen-Space vs. Native Ray Tracing
If the depth map looks inverted or broken, go to the tab, click Edit Global Preprocessor Definitions , and change RESHADE_DEPTH_INPUT_IS_REVERSED from 0 to 1 (or vice versa). Fine-Tuning Your RTGI 0.33 Settings
Open the game and press the Home key to bring up the ReShade overlay. 4. Configuration: Configuring the Depth Buffer
Tip: If your screen looks inverted or completely black when testing depth effects, toggle the RESHADE_DEPTH_INPUT_IS_REVERSED or RESHADE_DEPTH_INPUT_IS_UPSIDE_DOWN global variables in the "Home" tab settings. Optimization and Best Settings
