alt Hacker NewsConsole vs PC is a red herring since UE games still stutter on consoles, people just notice that less because most games run at 30 fps anyway. You can read Unreal's own blog posts on this and they'll actually explain that this is mostly down to their material system (and game logic/scripts reaching into it) being designed to create nearly infinite shader variations on the fly in response to arbitrary world/game states. This design choice separates engines which have shader stutters from those which do not.

Yes, that’s what I said. Powerful and flexible, at the expense of not being able to know how it will be used ahead of time.
Bundling and precompiling is not a fool-proof guarantee but it is very effective. Most often when a game has shader stutter the developers have not bundled or allowed the shaders to compile before gameplay starts (or it’s actually some other unrelated issue). The engine doesn’t do it automatically.
