Thing is, if some of the people here are be believed and there is no difference between RT on and off, maybe it is not working and you just think it is?I haven't checked for indirect lighting yet but definitely ray traced reflections are working in Windows 7 and it allows me to enable all the options for ray tracing.
Unfortunately because it uses DX12 for Windows 7 I can't check framerate in 7 but feels around 30-40 FPS with everything on ultra - doesn't support DLSS in 7.
