I'm running an XP SP3 install in a VirtualBox under OSX Leopard which works fine, apart from the input lag. I find that when I move the mouse in the VirtualBox that the input is a bit jumpy or sluggish. Obviously on the rare occasions when I boot my MacBook Pro into XP this isn't an issue, it's only in the VirtualBox. Is there a setting somewhere that I've missed which would reduce this input lag? Thankyee.
