If you’ve not already, please report any issues you find that have regressed or are “bugged” from intended or expected behavior so they can be properly investigated and reported where possible.

As for LPV and SSGI, these are both experimental and unsupported features. SSGI is not yet ready for production and is not a feature we’re focused on marketing or calling out for the 4.23 life-cycle. It’s expected to be ready for 4.24, so expect to run into issues and incompatibility with other features.

For LPV, this is not an actively developed feature and any regressions are expected since we’ve been doing a lot of changes in rendering lately. These may or may not be resolved in a future release. It’s not a feature being actively developed by our Rendering teams.

It looks like this. In fact, RT AO, RT Shadow are already very good. RT reflection and translucency are also good. But if we want to run in real time, we still need a GI with good effect and excellent performance. SSGI looks like the future direction. It seems that it is very difficult to find a good real-time combination effect in 4.23.

By the way, SSGI in the previous rendering branch seems to be able to fuse RT effects properly, but not now.
