They work fine in windows calibration.It sometimes happens in game where I notice that they suddenly only move a less than half the travel they should.What I mean is about halfway thru my real rudder pedals range the in game pedals stop moving so I have a huge dead zone in the outer edges of travel.
As for a driver for T-rudders,I don't think its really needed unless you want to do some altering of the mechanics,like making the pedals act like brakes when you press a button.
