You are surely right, but I refrain from commenting on preview versions of the engine, as it’s most likely not getting the desired reach and impact.
However, I’m worried that dev feedback gets more and more ignored while UE turns into a sandbox for testing experimental (yet admittingly impressive) features.
But if your performance collapses by 50% from one “production-ready” UE release to another, it makes you wonder where Epic’s priorities lie these days.
