Guild Wars 2

At the moment, whenever there is a new update, the launcher displays a number of files remaining and the progress bar moves in relation to that.

That doesn’t actually convey much useful info as each file could be any size. This causes the progress bar to stutter and leap forward, then stop while it downloads that one file.

If I see the launcher has downloaded 20 Megs, 3 files remain, and the progress bar is at 95%, how much longer until it finishes the update? We don’t know. Each of those 3 remaining files could be 20 Megs each for all we know.

They obviously know the total number of bytes the update contains. If the progress bar updated according to X out of Y bytes downloaded it would move smoothly along it’s length and we would be able to roughly estimate how much longer it’s going to take to finish.
