I've had a look through your latest Log.txt file and to say that the data entries look very strange, is something of an understatement!
Basically there are circa 25,000 entries like this:-
time= 98.5, RECV label=BECN from IP=192.168.178.76-49707, length after packaging removal=34 Private-message parse, RECV label=BECN, len=34
followed by a further 1,500 entries like this:-
frame= 16 OGL= 0.017 CPU= 0.000, GPU= 0.000 epr3->epr4= 16
This is most unusual and not something that I have personally seen in all of the XP11 Log.txt files that I've look at!!
I have however carried out some research and found one other simmer that has experienced almost exactly the same problem, and that was an issue with the LiveTraffic plugin.
I would therefore suggest in the first instance that you copy and paste the LiveTraffic plugin file to somewhere safe outside of the XP11 file structure to see if this make any difference?
At the same time, it may be worth you making sure that you have the very latest drivers installed for your GeForce GTX1060 graphics card.
Let me know how you get on?
