Yesterday night I wanted to make a flight from EGKK to KSEA with Norwegian B789. I had the latest update applied via their updater "version to version". Did not make a full install, maybe a good idea?

But I had many problems in the flight, and after around 4hrs the sim crashed. So I had no intention to once again restart everything. My problems where the following:

• performance is changing, even with a GTX 980 TI and refresh rate set so 11 by default I always have more or less good frames
• airport charts on ND display are not present since the first update. I have at no airport these even after new install
• crash during departure (I used a tool to get the correct time at the airport but it crashs, maybe not the fault of QW)
• is not able to follow a VNAV path according to the SID limitations, in EGKK you first go on 5000ft and then later onto 6000ft. I goes up to 6000ft straight. In FMC its correct displayed
• after 4hrs crash with "prepar3d.exe got a problem and has to be quit"

In general a nice plane but with these crashes and faults flying online is a mess. I thought there was a kind of crash reporter build into QW787? But I could not find it in the manual?

You flew the aircraft and used P3D for 4 hours and no problems and you are blaming P3D/QW787?  How can this be?  Most crashes are caused by incompatible textures/objects/AI.  If you have any product installed that is not compatible with P3D, suspect it as the cause.

You as the pilot is responsible for checking and monitoring the FMC after programming.  I suspect you are saying the FMC indicates you are supposed to be at 5000ft at such and such a waypoint and then to 6000ft at the next waypoint but it goes immediately to 6000ft?  Is there something wrong with that?  As far as I know, as long as you are above or below or right at an altitude at such and such a waypoint, no problems unless ATC told you to stay at 5000ft and did not allow you to go to 6000ft.  In the FMC, you might see 5000A or 5000B indicating you need to be above or below an altitude at a certain waypoint.  You are simply following the data in the SID.  Make sure you follow the tutorials and initialize the EFB Onboard Performance Tool (see page 38 of the tutorial).
