FSX Loading Flight (Terrain Data etc.) suddenly very slow - help!

Recommended Posts

Hi there all,

 

I am at a complete loss and almost at my wit's end with this problem I am having.  FSX boots fine.  But where it used to take, say, 20-30 seconds to load a new free flight, it now takes 5 minutes or more.  I have been testing at YMHB and FAJS (both quiet airports) with no traffic, and in the default tricycle thingy.

 

The problem developed on my previous (very clean, low-addon and virtually unused) FSX installation, which I only installed a two months ago.  I removed it and the add-ons and reinstalled from scratch.

 

I reinstalled FSX, and addons one-by-one and the problem has returned the day after I have installed it.  In this installtion, it happened after I installed EZCA V1.16, but I then uninstalled EZCA and the problem is still occurring, so I am in doubt as to whether it caused it.  In the previous installtion, it happened after I installed the Aerosoft Airbus and EZCA had been working fine.  I uninstalled the Airbus and the problem persisted. 

 

I have tried booting FSX not allowing it load any modules, rebuilding CFG, disabling add-on scenery, disabling anti-virus etc, uninstalling add-ons etc.  The drive has defragmented last night.  FSX has its own folder in C drive, anti-virus is excluded from there, and I run it in administrator mode.

 

I don't know what else to try and I obviously can't reinstall every day.  I was hoping some of you on here might have some experience with the issue and/or advice?

 

I have included my log of the FSX install and troubleshooting process below.  The only add-ons I have are listed there.

 

Thanks for any help you can offer me!

 

Cheers,

Rudy

Summary of add-ons and system specs:

 

FTX Australia

PMDG 737NGX

Do you only experience this issue with FSX? Or other programs loads slowly as well? I had similar issues a few days ago, after running Windows update. Tried to check the hard disk for errors then it became fine.

Only when loading flights or starting a new flight in FSX.  The program launches fine and the computer is running normally. I'll give your suggestion a go, but I doubt it's the culprit.

 

Thanks for your idea,
Rudy

Problem seems to have resolved itself after more fiddling, I was still unable to isolate what was causing the problem.  Will see if it returns, which I supsect it might as I haven't found the cause.

 

Updated log below with details of my fiddling in case someone else who has this problem might find it useful:

Further investigations show that svchost.exe service in task manager is sometimes taking up 50% of CPU when FSX is trying to load.  Not sure how I figure out what has "launched" that particular svchost.exe instance (there are many of them at once), but I'll try and get to the bottom of it.

It appears to be due to wuaserv.dll (to do with Windows Update) running from that particular svchost.exe.  After several hours of searching and trying a million things to fix the issue (Windows update used to work fine, now it hangs when checking and has this svchost.exe/wuaserv.dll CPU usage problem), good luck to anyone trying to fix it.  Temporary solution is to disable wuauserv apparently - but then, no updates!

Maybe just disable "automatically check for updates" and do it manually every a few month.

Yeah that'll have to be the way for the time being.  Anyway, as long as the wuauserv service is not running, CPU + FSX are happy!
