    can you test with a brand new character.
    are you using any macros? can you try deleting all your macros (save them to a txt file) and try without any macro. 

    Hey Dugi, sorry for the late respone. But it seems it got fixed in the last version 1.101. No lag now, FPS at 50-100. But thats in busy cities or cramped areas, the normal is 100 fps.
