UE4 slow perfomance and crash

[Olivierus]

Hey there leap motion users,

I'm having some trouble with the leap motion in UE4.
Performance is very bad, and after 15 seconds the plugin just quits and i'm left with 2 frozen floating hands.

Does anyone have a idea what could cause this.

Much appreciated,

Olivierus

So there no one who knows what could cause this?
