Thats too bad, it actually improves framerate for those who are willing to sacrifice sound for better game preformance, especially for those times when everyone is spamming AOE.

Its a known trick for another game Inotia 2, and I use it all the time. Another way to kick this in is to set an alarm to sound just after you log in. But I assure you it makes a noticible difference on the 3G, not sure on 3Gs. Turning off sound in game does not provide the same preformance boost.

Oh well
