There is no non RTX GI, I disabled it, I’m trying to use RTX only for this scene. I don’t even have reflection probes, although adding them doesn’t show reflection either. I would imagine it’s an optimization thing, but I also imagine there’s a way to enable it.
Going by the manual, this seems to be a screen space effect or post effect, which then could not be seen by the raytracer. At least the name indicates that, -> Screen Space Global Illumination. Seems like you will need raytraced GI for this scene.
