TFDi Design has shared in a brief statement on their forums their Microsoft Flight Simulator compatibility roadmap. Based off their first trials with FSUIPC7 and MSFS, the team has announced that smartCARS 2 and PACX should be compatible with MSFS at launch. However, a few bugs remain, mainly concerning the flight pausing system within smartCARS, which can be turned off anyway within the software.
The team however stated that they had no immediate plans on bringing their Boeing 717 to MSFS, and has not confirmed nor denied any plans regarding their upcoming MD-11 and the new simulator.
