Imho such statements are simply unfair, unnecessary and unprofessional. Epic marked the release clearly as ALPHA. This means it is far from completion. They stated that this is no build for productiin use but only for testing purposes. Most people who now complain that there is no ready release either don’t know how complex it is to build features like nanite, lumen or engines at all or they simply ignore what Epic told us.
They also never gave us a date and as long as they don’t do this it is silly to think about productive ue5 game releases.
The people who are switching now to ue5 simply ignore the facts, that it may take some time (like a year or two) until a real release.
Furthermore everyone who says that he needs lumen for the game is simply not correct. 99% can be achieved with baked light or current lighting features and often looks better. It is simply more afford needed. Same is with nanite. You can generate LODs in ue4 with a simple click on a button for skeletal and static meshes and in most cases you don’t need it on runtime. It is simply more afford needed.
You also have to use non nanite and non lumen features in ue5 when you want to support low end systems, this will not be changed by ue5. Ue5 will not ve a magic box which solves all your problems with a click.
I like ue5, too but in most cases it is not needed but nice to have.
This is only my opinion.
