: You need ReShade version 5.0 or higher installed on your target game.

The newer versions (from 0.51 onward) bring ray traced , improved sampling, and split diffuse/specular components into separate shaders. However, for users who prefer a battle‑tested version without sudden changes, 0.36.1 remains a safe and capable choice.

Reshade RTGI is a real-time global illumination shader/effect for ReShade that simulates indirect lighting, soft shadows, and ambient light bounce inside games and real-time renderers without native ray tracing. Version 0.36.1 is a minor update in the 0.36.x series focused on stability, quality tweaks, and performance refinements.

Enable this to generate micro-shadows under characters' feet, small pebbles, and foliage, removing the "floating" look common in older games. Performance Tweaks

: The game must allow ReShade to access its depth buffer. Competitive multiplayer games with anti-cheat software usually disable this to prevent wall-hacking.

Launch your game and press the key to open the ReShade overlay. Complete the initial tutorial. Go to the Add-ons tab at the top.

Version 0.36.1 introduces critical performance optimizations and stability fixes. This guide covers everything you need to know about installing, configuring, and mastering RTGI 0.36.1. What is ReShade RTGI 0.36.1?

Because RTGI relies entirely on the depth buffer of the current view, it light objects that are behind you or behind a wall. If you turn around quickly, you may see light changing unrealistically. For slower‑paced games this is rarely an issue, but in fast‑paced shooters the screen‑space limitation becomes more obvious.
