P3D and swift - 32 or 64 bit?

The ideal choice for using P3D with swift is the 64bit version. However, for P3D before V4.2 you need to use swift's 32bit version! You can try the 64bit version, but most likely the driver will not connect.

You can also use the 32bit version with the newer P3D versions, but then always the legacy FSX driver will be used.

• swift 64bit version uses the latest P3D SimConnect API and library
• swift 32bit version uses the FSX SimConnect API and DLL

In the mid and long term, the new SimConnect will use newer P3D API functions that are not available in legacy versions of SimConnect. So far, the differences between the old and new API are minor, but they are steadily increasing. As of P3D V4.2, swift has already been using newer functions and we are going to use even better functions available in 4.3 and later.
