For the record what people are complainig about in the G940 is a roughly 10% area around the center of the stick which does not have (intentionally so) any FFB--including centering spring. This is not to say that the sensors of the stick are inprecise--which you might think if upon hearing about centering problems. However,
Logitech themselves have stated that they are looking into and that it can be fixed via an updated driver. I have no idea if they will follow through on this or not however.
