Looking at the Witcher Next Gen Enhanced Trailer (which is PC footage I assume) - it looks like they have RT reflections on PC perhaps based on the behaviour of the reflections on water (no disocclusion weirdness one sees from SSR). Regarding "RTGI", RTGI and RTAO were mentioned in tandem on the stream. RTGI in its per-pixel form negates the need for larger ambient occlusion as AO is just a sub-set hack to get indirect shadowing effects. That implies the RTGI in use is perhaps not per-pixel, maybe probe based like DDGI/RTXGI.
RTAO seems omnidirectional.

Но да като излезе ще е по-лесно да видим.
