the problem still existst..for me and soooo many other users...and the problem is not our hardware or somethin, its a game-software-problem.
the only solution is to run the game in a special compability mode(all know it is the "Windows Xp SP3" mode) but this is only an option with the 32bit client
please devs, find a solution ..i paid until now 2 months and can't play as well... this is not the way
thanks and good luck to fix the problem fast as possible
