Reshade Ray Tracing Shader Rtgi 0.33 Link

For years, the PC gaming community has been split into two distinct camps: those who own an expensive NVIDIA RTX GPU and can toggle "Path Tracing" in Cyberpunk 2077, and those who rely on raw rasterization power, hoping for a slice of that visual fidelity pie.

Enter Reshade Ray Tracing shader RTGI 0.33—a version number that has become legendary among modders, retro-gamers, and optimization junkies. While NVIDIA’s DLSS 3.5 and AMD’s FSR 3 dominate headlines, this specific shader version (0.33) of Marty McFly’s RTGI (ReSTAR DI) remains the gold standard for adding global illumination to games that never had it.

But what makes version 0.33 so special? Is it actually "ray tracing"? And how can you install it without frying your GPU? This article dives deep into the technical nuances, performance impact, and the best games to resurrect using this shader. Reshade Ray Tracing shader RTGI 0.33


Installing RTGI 0.33 is not as simple as dragging a file into a folder. The author, Marty McFly, distributes his shaders via Patreon (though legacy versions can be found via community archives). Here is the safest, modern way to install it.

Ghosting has always been the Achilles’ heel of screen-space GI. 0.33 introduces more aggressive but smarter history rejection. Fast camera movements now show far less trailing. The trade-off? A tiny bit more noise for 1-2 frames, then it cleans up. For years, the PC gaming community has been

As of 2026, how does an old shader stack up against modern tech?

The Bottom Line: You don't use RTGI 0.33 to beat Alan Wake 2. You use it to make Mass Effect 2 look like it was released yesterday.
