A: RTGI is a screen-space effect, meaning it can only calculate light based on what is currently visible on your screen. This is incredibly fast but has limitations (e.g., light from objects behind you will not be calculated). Full Path Tracing in games like Cyberpunk 2077 's "Overdrive" mode calculates light globally, including off-screen elements, which is exponentially more demanding and requires dedicated RT hardware.

Run the installer and select your game's executable ( .exe ) file.

Runs on NVIDIA GTX/RTX, AMD Radeon, and Intel Arc graphics cards. How to Download ReShade RTGI 0.33

If your screen turns completely black, white, or nothing changes, navigate to the tab in ReShade.

The quest for graphical fidelity in video games has historically been a battle of deception. For decades, developers relied on "baked" lighting—pre-calculated shadows and highlights painted onto textures like a theatrical backdrop. While effective, these static environments lacked the reactive dynamism of the real world. The emergence of tools like Marty McFly’s RTGI (Ray Traced Global Illumination) for ReShade represents a pivotal shift in this narrative, democratizing sophisticated lighting techniques and bridging the gap between legacy software and modern visual standards.

This guide provides everything you need to know about RTGI 0.33, including a detailed breakdown of its features, where to download it, step-by-step installation instructions, performance optimization tips, and answers to frequently asked questions.

Setting up RTGI requires a specific installation sequence to ensure the depth buffer reads correctly. Step 1: Install ReShade Launch the ReShade installer. Select your game's executable file (.exe).

Higher values increase the precision of the shadows and reduce noise, but heavily impact frame rates.

Launch your game and press the key to open the ReShade overlay. Check the box next to qquint_rtgi .

However, I can offer a covering:

It works on both NVIDIA and AMD cards, as it relies on depth data rather than proprietary ray-tracing hardware.
