Released during the 2021–2022 period as a significant update, version 0.33 introduced technical improvements to enhance both visual quality and performance: Motion Vector Support
The 0.33 update solidified Pascal Gilcher’s RTGI as an essential tool for the PC gaming modding community. It breathed new life into classic titles like Skyrim , Fallout 4 , and The Witcher 3 long before official next-gen ray-tracing patches were ever announced. It proved that clever software engineering could replicate advanced hardware features, democratizing high-fidelity lighting for gamers everywhere.

Best used with the "Launchpad" pre-pass shader, which provides motion estimation using optical flow for more precise lighting updates.
This screen-space limitation is why moving your camera quickly can cause light to "pop" in or out—a flaw tolerated by most users given the zero cost to developers and the lack of native RT support. If you want to customize your setup further,
Because RTGI 0.33 computes lighting entirely via software shaders, it does not require dedicated RT cores. It runs on both NVIDIA and AMD graphics cards, though it demands significant GPU compute power.
