Problems in Leviation
 

Why i am dropping faster than the other group member when moving in DL during Leviation?? Is it related to my PC hardware?

Are you hitting the 'pg up' key? Similar to swimming, Page Up and Page Down can manipulate going up in down in the air as well.

Beyond that, it is also tied to your fps. With 100 fps, I can float very well. If I do something that causes my fps to drop, such as tabbing out then I will start dropping out of the air

Definitely more than likely the fps thing, or your internet could be laggy. Check your options and raise your max fps.

My FPS is already set to 100 and i do page up already, but I still get this problem.

this happens to me when I have things open in the backround. If i minimize them it seems to stop.

i checked my FPS by using Fraps, only 50 in game....maybe this is the reason
