Controls how far the light rays travel. Lowering this reduces performance costs in wide-open outdoor areas.
The RTGI (Ray Traced Global Illumination) shader, created by Pascal "Marty McFly" Gilcher, elevates ReShade's capabilities significantly. Rather than just applying a filter, in real-time. By analyzing the game's depth buffer and normal map information, it calculates how light would bounce off surfaces within the scene. This results in more realistic shadows, better light distribution, and enhanced depth perception.
Officially, the RTGI shader is a hosted on Marty's Mods Patreon , typically requiring a subscription to the "Beta" or higher tiers. reshade ray tracing shader rtgi 033 free
Installing and using the ReShade Ray Tracing Shader RTGI 0.3.3 Free is relatively straightforward:
The effect flickers or looks like "soup." Solution: Screen-space ray tracing requires a depth buffer. Go to the ReShade "Add-ons" tab and ensure "Copy depth buffer before clear" is checked. Also, disable anti-aliasing in-game (use ReShade's SMAA instead). Controls how far the light rays travel
Launch your game and press the key to open the ReShade overlay. If the depth buffer isn't configured correctly, RTGI will look like a blurry mess or do nothing at all. Head to the DX11/DX12/Vulkan tab in the ReShade overlay.
Run the ReShade installer. Click "Select game" and locate your game's .exe file. Select the rendering API (usually DirectX 10/11/12). When asked to download a standard shader pack, say "Yes" – this gets you the basic effects. Rather than just applying a filter, in real-time
Select the correct rendering API (DirectX 11, DirectX 12, or Vulkan).
Pascal Gilcher develops the RTGI shader as a passion project funded through Patreon. Access to the latest stable builds and beta releases is traditionally locked behind a monthly subscription tier. This has led to a massive demand for cracked, leaked, or "free" versions of the shader online.
