Game Problems of slowness

[Zedara]

Hello, since the high five i can't play well. I play with 20 fps max, always i have L2 breaks and slow loads. In other servers i have 50 fps more or less with the same PC even playing same "chronicle" H5 and Goddess of Destruction i play well. I think is a problem with server files. Help me please, i can't do anything with 10-20 fps. I've tried everything and i can't fix the problem. Thank you
