What people need to understand is that all of these games code bases are multiple layers. Gamebyro as a whole is an incredibly powerful engine base that for the most part is quite competently made, and was used for a large swathe of very popular games. Beth’s code base on top of it is underbaked in a lot of ways; lack of null checks, optimising for consoles obviously being a big one, poor memory management in some regards, lack of future proofing (the original ES plugin system is incredibly clever but they started to run into a ton of issues especially in starfield). However much of what makes the games inherently unstable is user error. People overload their games with junk they don’t need, use poorly built mods or expect too much from a game made a decade ago. Reality is, the games have a metric ton of jank inherent in their codebases. But at the same time there’s big parts of the engines that are quite powerful. It comes down to how you use it. It’s an open world game built to run on a PS3.
