I can comment on regarding VXGI. The tech (not its UE integration) is currently being ported to , but it’s too early to say anything about performance. I wouldn’t expect much speedup for VXGI from , primarily because it is very GPU limited, and is focused on reducing CPU overhead. Speaking of new rendering features, everything that was required to accelerate VXGI was available on through NVAPI; makes some of these features available as core, but not all of them.
