I have a gtx 1060, 16G of ram, i7-4790k, using active sky 2016, orbx NA, Global and vector
I put the aerosoft airbus 319 at gate C3, ran GSX and got right to the point where the baggage cart was pulling up and P3D V3.4 crashed.
After already configuring the airbus for the flight, and sitting back watching all the cute little animations (about 15-20 minutes into it) I just said hell with this and went and did something else, rather than re-do everything- usually it will just happen again.
Also, I go under services in task manager and close EVERYTHING thats not vital to the sim.
Draw your own conclusions....

( it does LOOK better than the other one though, very nice modelling)
