The traversal stutters occur regardless of what kind of rig you got. You can run Silent Hill on a monster machine and it will still stutter, at least as it is currently late 2024.
But shader compilation issues are still not inherently a UE5 problem.
Traversal stutters however is, as it has been demonstrated that there is something seriously wrong with how the engine syncs its supporting functions (like animation and world transition)
No, and you probably wouldn't need one either since very few people actually need that type of computation power today.
The only argument here is that you have a special use case.
