Pretty sure that’s what it means, hence not super happy to include it on these merges (I prefer having things that people can actually use on commercial games). You can run VXAO on lesser hw (probably also on AMD?), but not the VXGI. Afaik there’s not a single (well known) game out there using VXGI but there are few AAA games that have optional VXAO mode.
There are use cases for Nvidia only stuff if you do visualization / presentations on fixed hw though.
