Question Raytraced GI doesn't look right

Can somebody explain to me what I did wrong here? I suppose there is some raytraced GI, but it looks horrible and nothing like what was shown in the demo video. The baked lightmaps keep getting used unless you clear baked data, and if you do clear them the exposure gets screwed up and the GI is very underwhelming even if you bump up the raytracing parameters.

 

It's bugged for me too, current techstream version is broken when it comes to raytraced GI, also new alpha, previous alphas are working fine

 

I read the raytracing troubleshooting guide and think I found the problem:

The thing is that the second option here does not work. I can bake the reflection probes, but that leaves me with static lighting again and means I can't turn off, move, or otherwise modify the lighting conditions which kind of defeats the whole point of using raytracing in the first place.

On one hand it's kind of my fault for struggling with this because I didn't see the troubleshooting guide right away, but on the other hand I don't think it's very intuitive to set up the process of enabling raytracing in such a way that it depends on baked data by default. I think most people expect the raytraced features to be purely realtime and independent of baked data once you enable them, especially since that is how it is presented in the two official demo videos about it.
