Levivate problems

[Aposi]

Okay, i am not sure what could be wrong with my files and what not.

When i receive Dead Man Floating, Levitate, Etc. I don't levitate, I mean, it does. but about a millimeter a second making my screen have a major seizure because he barely levitates and yet so fast.

When i am alt tabbed though and can see in the game, I levitate normally like in classic, slowly descending, rising, etc. Anyone know a way i can fix this because apparently other necros and other people with levitate are not receiving the same problem i have from asking around.

-Thanks, Aposi
