Not going into all the technical aspects but I do understand the differences and the advantageous as far as multitasking and stability is concerned.
I don’t understand why they didn’t include a 64 bit client standard with the game since this is a New Generation game. I guess its the same excuse category as why there isn’t DX11 support yet either.
WoW and Aion introduced a 64 bit client a while back and there are noticeable performance differences. These are old games and they made the jump already.
Also most (not all) users now days will have a 64 bit capable system.
Please add it thanks
