Hi, I was playing around with the new SSGI added in HDRP v10 and Unity 2020.2 but I can’t get it to work.
I started with the sample scene. I have a single volume that has SSGI enabled. The HDRP asset in use also has SSGI enabled. But there is no visual difference between ON and OFF. I can’t get it to work. Is there something Iam missing that I need to do in order to turn it truly on?
It does work but it is a very subtle effect you could use the debug view to verify if it’s actually there or not, but in my experience, it’s mostly not that useful if you are not using RTX as well sadly 
It is improved in 2021.2 version

You might want to check your HDRP Default Settings and check if it’s enabled there (it should be disabled by default).
If that’s the case, that means you won’t be able to see it in scene view, and for the game view you’d have to enable it in your custom camera frame settings.
I did eventually get it to work in an empty project. Apart from cutting the performance by 80% it looked like colored ambient occlusion. Like, it was better than AO by itself but not worth the performance at all.
