My slew speed has slowed down to what seems to be 1-2 knots where before i could go lightspeed forward backward etc. Anyone know how to change it?

 

TIA

As far as I am aware, slew speed will always depend on the view you're in - fastest speed is possible in top-down view, slowest is probably in VC view.

To speed it up you can press the corresponding keys longer (or more often) or if that is still too slow, you can also increase the sim speed.
