Navigate to your game's installation directory where the game executable lives. Open the newly created reshade-shaders folder.

Best for virtual photography or screenshots. It dramatically increases the ray count but drops frame rates significantly. 2. Ray Length Controls how far the bounced light and shadows travel.

The primary feature of version 0.33, created by Pascal Gilcher (Marty McFly), is the introduction of spatial and temporal denoising improvements , which significantly reduce the "noise" or flickering often seen in real-time ray tracing. Key features and updates included in the 0.33 release are:

Once you have downloaded both the ReShade installer and the RTGI 0.33 shader package, follow these steps to get it running. Step 1: Install Base ReShade Run the ReShade installer executable.

The RTGI shader is developed by Pascal Gilcher. The official, legal, and safest way to acquire RTGI 0.33 (and its newer iterations) is by subscribing to his official Patreon page ().

Set between 10.0 and 15.0. Higher values cause performance drops without adding much visual accuracy. Ray Amount What it does: Dictates the number of rays cast per pixel.

(also known as Marty McFly). This version, released around August 2022, notably introduced motion vectors to improve visual stability. Official Download Source

Select your game's main .exe file from the list (or browse to its installation folder).

A major benefit of v0.33 is its extensive support from the modding community. Many preset creators specifically designed their visual overhauls around this version to maximize compatibility and performance.

to calculate how light bounces off surfaces in screen space. Global Illumination

Unlike native hardware ray tracing (like DXR), which calculates light paths throughout the entire game world using dedicated RT cores, RTGI works entirely on the pixels visible on your screen. Version 0.33 introduces specific performance optimizations, improved filter denoising, and better handling of emissive light sources, making it a favorite for gamers looking for a balanced performance-to-visual ratio.

Tuning for performance

John decided to take a cautious approach and started to monitor his system's performance closely. He also made sure to keep his GPU drivers up to date and adjusted the ReShade settings to optimize performance.
