Did NTE upgrade to UE5.7 at launch? What changed?

Engine-upgrade pages age quickly when they present one launch build as if every detail stays fixed forever. For current users, the more practical question is **what changes were associated with that upgrade, and which of those observations still need to be validated against the live build you are actually playing.**

A safer reading is:

1. Treat UE version mentions as build context, not as the whole performance story by themselves

2. Visual, loading, and feature differences can still vary by later patches, platform, and device class

3. If you are troubleshooting performance, current patch behavior matters more than preserving every launch-day expectation

So this page now works as upgrade context rather than an evergreen feature-confirmation list.
