For comparison, Unreal games that don't get extra optimization and love during development have engine-standard issues. Star Wars Jedi: Fallen Order is notoriously affected by Unreal load/unload lag spikes, even on console. Every Unreal game will do this to some extent unless that behavior is dealt with since it's just how Unreal handles large texture swaps.

So yes, an engine can have known issues, but isn't it up to the devs to make a product that runs well? Unfortunately for Jedi: Fallen Order they just weren't given time to make it work well, just "good enough" for console, and it's even worse on PC. The sequel has the same issues.
