I use UE5 as an Indie Dev, and I can honestly say if I hadn’t spent the better part of using UE5, I would go back and use UE4.
There are still so many things they need to work out with UE5 for it to be at the level UE4 was/is. Things that worked fine in UE4 struggle performance-wise bcz they changed the algorithms so much, generally for the better, bit they haven’t seemed to figure out how to make a lot of things performant yet like they should be.
That said, companies have a whole other level of support with their licensing agreements, so I wouldn’t take what I have to say with a grain of salt.
Overall UE5 is a major improvement over UE4, it’s just gonna take time before features like world partition have all their bugs and kinks worked out. I would still prefer the old world composition solution for open world games over the new stuff after my most recent experience.
You can build massive world’s with the UE4 solution of world composition, and they haven’t deprecated that, so they were at least smart about not getting rid of systems prematurely. And from my understanding they have no intention of depreciating the old system since so many people use it. Just my two cents on the subject.
