Hi Captain Foxtrot
I'm not with Laminar Research, just a fellow simmer in the UK and have just come across your post.
I've had a look at your Log.txt file and to say that it looks unusual is a complete understatement! There are literally hundreds, if not thousands of unexpected entries, mainly similar to the three types shown in italics below, which I have copied and pasted directly from your Log.txt file.
In summary, there are three issue types being reported and they are related to 1) the Xsquawkbox plugin, 2) something referred to as a "low end LAN" (local area network) and 3) problems opening default scenery objects?
Something is obviously very wrong here and it maybe that you will have to try various things to overcome these strange issues
1. Do you have the same problem with any other aircraft, the Zibo 737-800X for example? If not, then try deleting the 900U aircraft and redownload another copy of it.
2. Try deleting the Xsquawkbox plugin to see if that improve things?
3. Certainly double check your PC hardware specifications and use a third party software to stress test your PC to make certain it's able to handle X-Plane 11?
I'm not sure what else to suggest currently and am currently on vacation replying to you without having the benefit of X-Plane 11 being in front of me. Anyway, left me know if any of this helps?
1. XSB WARNING: Parse Error in file D:\XPlane11\Resources\plugins\XSquawkBox\64\..\Resources\CSL/BB_Leipzig_Air_VA/xsb_aircraft.txt line 5. VERT_OFFSET 3.6.
2. WE ARE SENDING 0.00 kilo-bytes per second (1,200 kilo-bytes per second is a low-end LAN) WE ARE RECEIVING 0.06 kilo-bytes per second (1,200 kilo-bytes per second is a low-end LAN) time= 36.3, RECV label=BECN from IP=192.168.137.199-49707, length after packaging removal=25 Private-message parse, RECV label=BECN, len=25
3. Will try to read the OBJ, path=Resources/default scenery/sim objects/apt_lights/slow/inset_centerline_twy_G_uni.obj
We already have that object! Index=0000020A7068ECB0, so we will use that index rather than re-loading the object.
