Hi!
Not sure if this is technically a bug or maybe just a feature, but I think the software should work still after performing a driver swap in rFactor 2. So specifically when you take over the car from another driver. There are other plugins that do not work in the same situation but also some that do work.
I regularly use DashMeterPro, Fanaleds and the Motec plugin. Only DashMeter works when doing a driver swap.
Thanks!
