Dual Client problem

[allanrma]

I used to Dual cleint with no problems at all, I play windowed. But now when i dual client, the client am not curently using freezes. When i switch back to the second account, everything that was supposed to happen while it was frozen, happens but in like fast forward. The only way i can fix it momentarily is by changing the priority in the task manager, but it only solves the problem while am not using the second account. please someone help me

I get that from time to time when I dual client.  I thought it was my slow computer that can't handle the two clients' graphical movement at the same time?

As long as it doesn't disconnect and you are just leeching it's fine. (for me that is ..)

(moving to RO support.)

Are you using a laptop? Because some of my friends have this problem and they all use laptops.

i have the same probem Q.Q

The Game will take 100% Cpu-usage(Idle).

When I run a second Ragnarok the first one freeze.
If I switch back to the first one, the game is fine again, but the second freeze, so Dualclienting is impossible.
