You do realize that people who only own ‘normal’ machines are not exactly the audience who go through this workflow. New people to UE4 will not at all.
I would not! I mean, Epic, just publish a lighter version of the thing as well.
You can not be serious…8K.
No game in the world uses this. No-one will notice any difference to what they have seen so far in any of their games.
Really, if they decide to only publish the 8k version and only a handful people will be able to open the thing after hours of loading time, then they can just keep it.
