It isn't my internet connection, WoW and other internet applications run smoothly with low latency, and I've reset my connection to see if that does it, and it does not.
I have a supported graphics card, an ATI 3GB card. 6GB of RAM.
I am supposing that this is simply a server side issue, but I also supposed that the open beta weekend to stress test the servers would provide enough preparation so that when the actual game launched, people wouldn't be having problems like this. This wouldn't be a problem if being connected to the server were not required for single player, but that is an issue for another time, in another forum.
Either way, I hope blizzard stabilizes so that *everyone* can enjoy the game.
