If you play Blizzard's World of Warcraft, then you probably know that not all the changes made in every patch is documented in the patch notes. Blizzard QA Hortus explained that adding all the changes would make the list of changes far longer than necessary.

Blizzard Tech Support Datth dropped by to confirm what "the gnome" (Hortus) said. To further illustrate the point, he mentioned that there are "a number optimizations in the game engine that may help with overall performance and FPS" but the changes are too numerous to list.

It makes one wonder what optimizations were made to make the game run better and faster than before. Hopefully, we'll find out more about this in the near future. Till then, keep checking back here for more updates.
