I've seen it before, and it's ugly. (Destiny)

I played Reach firefight with teammates in Australia, Belgium, and the UK once. It was 1 frame per minute slow.

Given how Reach's Co-op netcode worked, You're probably thinking of ODST or Halo 3, but I get the gist of your post.

Reach's co-op net code (and Halo 4's code, for that matter) were largely the same "synchronous" net code model as Halo 3 & ODST, suffering the same problems :(

Eh?

Here's what I remember:

Halo 3 + ODST: Host waits for everyone's connection to respond before advancing a frame. Result: Game is choppy, plays in "slow motion".

Reach: Client sends their controller input to the host's machine, which moves the characters, then sends the resultant game-world back to the clients, in real-time.
Result: Clients have to "anticipate" their moves, because it might be as much as a second before you see the result of your input on the screen. Game is relatively smooth otherwise.
