By slow and laggy, i don't mean normal slow and laggy. It takes me more than 30 secs to login, and once i try to connect to a world, the screen just doesn't respond D: Any help is greatly appreciated.

I have that problem too (I think that it starts on the highest resolution, not sure)
Best bet is to use tab as much as possible to get past the username password screen, and if it works for you (It only works when I select world, not channel) to use the down arrow to choose your world instead of clicking, seems to make it a lot faster... I'm hoping when I get it loaded up that the resolution is on the highest mode so it can run better... good luck!

thx... but i tried that and it still didnt work D:
