Since the last WIN 10 update (to v 1709) on 01/06/2018 and the updates KB4056892 and KB4041994 the loading of my XP11 is extremely long (about 15 minutes) and the sim frames are now down at 3-5 f-act. I tried a second clean copy-> f-act @ 9.510, frame time 0.105, cpu time 0.112, gpu 0.100, grnd ratio 1.000, flit 1.000. Not playable at all. Even turning down the sliders from max. to low is no solution. Nvidia driver is actual (390.65). Think the actual intel orientated win 10 update is the problem, feels like sim has to go threw a small pipe. Time before I had a super smooth sim (with Ortho4XP, custom scnery,....). Everything was ok.
MY PC SPECS :
Z270X Gaming 7 mainboard
WIN 10 OS build 10.0.16299 v. 1709
KB4056892 installs the meltdown/spectre patches that reportedly can slow down your cpu by up to 30%. It's all over the news.
ADDITIONAL INFOS - READINGS FROM TASK MANAGER :
While XP11 shows the fps parameters like shown in my post above, the task manager shows the following values :
CPU : ~11% @ 1,2 GHz and ~ 1750 threads
RAM : 12,3/32 GB (38%) (in use 11.7 GB, avail : 19.9 GB)
Hard Disk : ~ 5 %
GPU : ~15 %
I think the pc is no longer fully powerfull as it was before the update. Thx Microsoft !!!
I have found the reason for my problem !! It was the Windows Defender - Antimalware Service Executable !!!
It ran a long time over the hard disc and checked X-Plane 11 everytime I pressed the .exe-file, too , until it has checked it completely. Thereafter XP11 started as fast as I know it.
Now I have XP11 excluded in the check process and everthing is fine.
