The preview builds are expected to have issues from all the sub-streams or branches of development teams coming together for a release. There is always some stabilization and fallout from the copy-up merging of all these branches together that has to be resolved and tested. These builds are part of our QA process to stabilize and catch issues before release. Having the community use them earlier in our process by having a lot of previews helps call out issues or edge cases we may have missed otherwise and it lets anyone who wants to try things out earlier get that first look.
With each release, we post the preliminary highlighted features for that release so that everyone is aware of what’s coming and they can start to try them out. For instance, Chaos is a big feature for this release, but it’s not the only thing we’re looking for feedback or bug reports on. Ray Tracing was released as “Beta” in 4.22 with the acknowledgement that there is still a lot of work to do. This release sees a number of improvements not only in stability but in some feature support for different geometry types and material types. RTGI is still very expensive and our devs are continually working to improve its performance but that too will take time.
All that being said, if you find issues, please report them! Even if you’re not sure they are a bug or lack of implemented feature or it’s a difference from previous release in how it works/looks that we’ve not intentionally called out, please report it. Our teams will investigate and be sure so that we can get fixed if it is a bug and if it’s not we’ll try to provide context where possible.
@Daffrendo thanks for taking the time to try out the preview builds and report any issues you find. It really is appreciated and helps make a better release when it gets here!
Now it seems that the rendering part of 4.23 has become very bad, especially ray tracing.
Until the latest 4.23 Preview 3, RTGI was damaged, RT translucency was completely disabled, SSGI could not be combined with RT effect, LPV could not be combined with RT effect, which led to the only available GI effect under RT Shadow was RTGI, but its performance was so bad. Many parts of ray tracing look terrible, even worse than 4.22.3.
The only consolation is that we have seen support for these categories of HISM and Ladnscape, but we still don’t know when these rendering problems will be solved.
