Levitate.. what am I doing wrong?

[Rompar]

Hey guys lately I've noticed when I levitate my character drops like a rock and I'm unable to run across small gaps that others are able to.

I'm not encumbered and I have myself looking straight up when I am trying to levitate across gaps in CoM and stuff. I'm also running Wineq lite

Someone said it was my clip plane.. and someone else said it could be my fps which is currently set to max = 100.

Has anyone else experienced this problem or something similar?
