RTGI too whatever that means. Is that full rt lighting like path tracing?

Also no hdr mention in the blog but I'm hoping for a surprise.

its the good kind of RT. basically it calculates light bouncing for more accuracy lighting. it really helps bring the image together

I don't think so because path tracing would simulate every single light source I believe? I think RTGI would mostly apply to the sun/moon lighting the environment but I might be way off

RTGI has a more limited amount of rays projected, I think. So while it is not as accurate as path tracing, it can still provide some nice quality improvement with a lower performance cost

I'll take it. I assume under the tables in corners will be darkened? Those kinds of areas really break immersion when going back and playing standard lighting games.

RTGI is Ass. Its some of the more barebones raytracing there is

Incorrect.

You must be thinking of RTAO

RTGI is the big one of the main-three:

Raytraced Shadows

Raytraced Reflections

Raytraced Global Illumination

Usually RTGI is the big game changer while the other two can be "nice"

Of course path tracing beats it all.

RT is just diet path tracing
