Why the netcode issue exists, and why it cannot be fixed.

[Illya]

TERA is special because it cheats. Theoretically it's easy to hack tera due to these cheating, but the korean programers seems to have some nice correction failsafes in place to make it hard to get away with it.

Just like ARR theoretically is harder to hack, but have been plagued with hacks from day 1.

Tera actually has netcode much like a dungeon crawler. It's very elegant from what we know of it. But that's why a lot of f2p instance MMOs run so darn well.

Tera runs on Unreal Engine, which has netcode optimized for online FPS where your latency is critical to everything you do, and also where cheating and hacking are really obvious and can be a problem if allowed to occur unchecked. They started with better netcode than FFXIV finished with when you realize that Epic Games has been coding their network engines since the original Unreal Tournament in 1999. They have nearly 15 years of experience with netcode, and it shows in all games which use UE3 like Tera.
