I managed, It is working now. I will make test flight to understand how much FPS will left, to install REX, PMDG,GTX ,AS and Ultimate Traffic, ORBX, some addons also.
MY base AP is Newark Airport in NJ.
I don't think P3Dv5 after all addons installed, forget the flying ,we will be lucky if we can taxi the plane.
I have TWO Titan X GPU. After QW146 installed , GPU's was generating 20 FPS, Takeoff was between 19-23FPS.
Future , doesn't look bright with P3DV5 , unless we all start to flying VFR .
May be FS2020 will save us
