I hear v4.4 will not accept a lot of FSX native aircraft due to 64bit.
I also guess that if P3D v4.5/ v5 / or whatever, goes to native p3d models only (so no FSX planes will work) is it really best to stick with v4.3 but no higher?
Because if it's native p3d aircraft only then years of files are wiped out? I hope not.
Or maybe 4.4 onwards will also accept FSX native as long as they are 64bit
