Hi

I am having problems with my FS freezing.

I recently upgraded my OS from XP PRO to Win 7. when I am about an hour or so into my flight the system freezes, when I go into task manager it takes for ever but it shows that my CPU is running at 100%. I us my FS, REX, PMDG 737-800 and my VA ACARS programs. I never had problems with XP. is this a Win 7 issue?

 

Steve

Plenty of people including myself are running FS9 on Win7 with no issues.

 

Does the windows event viewer give any clues ?

 

Does this happen anywhere in the world? If it does, then I would start by disbling REX and ACARS and see if you still get the problem.

Go to fs9 main folder, find and destroy "oleacc.dll"(rename it to "oleacc.dll.old or delete it"). Then, right click on "fs9.exe" and select "properties". Here you need to go to "Compatibility" Tab and select "Change settings for all users". In next window, select(check) only "disable visual temes", "Disable Desktop composition" and "Run this program as an Administrator". After that, click "apply" and "ok" untill you clear all opened windows. 

After that right click on desktop and select "Personalization"(or "Control Panel\Appearance and Personalization\Personalization"). On the left side, click on "Change mouse pointers". Under "Scheme" select (None) and under "Customize" select "Normal select". Press again "apply" "ok" until you close all windows.

This will fix many of fs9 problems.

Windows 7 is much better for fs9/fsx than XP. It's important to use 64bit version.

But you know, there can be too many reasons for all fs9/fsx issues. 

So i suggest you to use some guides about how windows 7 tuning and fs9 instalation, settings and tuning. This is what i recommend:

after looking at the event viewer I get the following from about the time and date this occurred. "Custom dynamic link libraries are being loaded for every application. The system administrator should review the list of libraries to ensure they are related to trusted applications". I don't know if this is the problem. BTW I am running Win 7 32 bit.

that event viewer message is not the problem....I get that all the time too!

The important question is: Is it actually FS9 plus your add on stuff that is causing the CPU to run at 100% or is it FS9 combined with other applications such as background tasks and AV, etc? What all do you have running from start up and background tasks? When, after what you see in task manager, you shut down FS9 does CPU usage go back to normal levels? Start your computer, let it set idle for about an hour then check task manager to see what the CPU usage looks like. You may find that other activity is a major part of the problem. If you find nothing to cause a problem there that could point to the installation or operation of one of your FS9 add on items.

Hi Mel

most of the time my cpu fluctuates around 15% to 45% using normal applications. I ran my fs9 not using the REX & VA ACARS and I got only 30 to 40 seconds of flight time. it seem that when I run the fs9 on its own I get less flight time. I ran the other programs on their own and the cpu only went to 20% or more.

What does the "oleacc.dll" do? and how does this help to increase performance? surely it is there for a reason? I have deleted it but no difference.

oleacc.dll is a library - microsoft active accessibility. 

 

this is not for performance, but for stability. You don't need it, and removal of oleacc.dll can solve all fs9 problems - freezeng, CTD's etc

See another 2 links for performance tuning, there is one guide http://forums.simviation.com/cgi-bin/yabb25/YaBB.pl?num=1211055375/0#7 how to set fs9 option display, and how to tweak fs9.cfg. I would change only two things from this guide 

1.set the INTERNAL FSX frame rate limiter to 30 (if you have a 60Hz monitor) - in nvidia Inspector, set Vsync to "1/2 refresh rate"

 2. Don't touch "TEXTURE_BANDWIDTH_MULT=" in my experience that can bring only trouble

 

BTW, freezeng and CTD's can happen if you have two DLL's conflict, two payware planes for example, but this you can find only by elimination metod - remove one and backup somewhere, and see if still happens

 

most of the time my cpu fluctuates around 15% to 45% using normal applications. I ran my fs9 not using the REX & VA ACARS and I got only 30 to 40 seconds of flight time. it seem that when I run the fs9 on its own I get less flight time. I ran the other programs on their own and the cpu only went to 20% or more.

 

Start task manager now, with nothing but your browser running and check CPU usage and note the number of processes running. Let us know what you find. There are many 'hidden' factors that may be involved. One example would be a anti virus program that is constantly checking and rechecking all of FS9 as it runs. Another would be one or more applications that automatically search for updates constantly or frequently.

 

I will assume for the moment that you have a limited number of processes running, a AV that is not a resource hog or over zealous and also that all of your hardware is performing normally. If, under those conditions, FS9 is pushing CPU usage to 100% within a few seconds / minutes of being started, I would suspect that there is a problem with your FS9 installation. That could be FS9 alone or a add on that is also set to run when FS9 is started.

 

As far as it possibly being a Windows 7 issue; if you have followed the guidelines and advice available here on AVSIM and elsewhere on the best methods for installing FS9 on a W7 system then I would think not. You may wish to double check that just to make sure you missed nothing.

 

You might want to let us know what your CPU specs are, such as speed and number of cores etc.

 

I would be very careful about the advice about removing the 'oleacc.dll' from FS9. The claim that removing it "can" solve "all" FS9 problems is questionable. Unless of course everyone in the flight simulation hobby knows about this magic fix for everything and have be cruel enough to make sure I never found out. After doing my research I found that the 'oleacc.dll' is a essential part of any Windows operating system since at least W98 and whether you refer to the one residing in your operating system or the one in your FS installation, it for the most part, like any other component sits there and does nothing until a application that is designed to use it calls for. If that call is made and the olecc dynamic link library is not found you get one of those nice little notices in the middle of your screen. Removing the one in FS9 probably, at best, would only slow your system while the application within FS9 that calls for it causes the OS to search for it elsewhere and finally finds (or not) the one located in the OS. PLEASE! Anyone with more or better information on this?

just google "fs9 oleacc.dll" and you will find all informations. Nothing to do with system stability, oleacc.dll from windows folder will still be in place. And you don't need to remove it, just rename it to oleacc.dll.old or move to some "backup" location

 I did 'Google' it and read about 20 pages worth of links. Thank you for assuming I didn't. I found nothing to support your claim of fixing 'all' FS9 related problems.

I assumed that you googled for "oleacc.dll" or "what is oleacc.dll" , not  "fs9 oleacc.dll" . Becouse when i type this in google i get this results:

As you can see, too many different problems caused by this dll, and solved by deleting or rename it. And many people's know about this for a long time, some posts are from 2004, 2006... And Microsoft recommend this too

 

I assumed that you googled for "oleacc.dll" or "what is oleacc.dll" , not "fs9 oleacc.dll" . Becouse when i type this in google i get this results:

 

Next I expect you to assume I can't read as well as you assume I don't know how to use a search engine. You presume to off hand dismiss what I have written as inaccurate. Thank you for all the trouble you went to to post links. I now know that the next time I have a faulty AI texture, a missing texture, a misbehaving scenery, a aircraft that doesn't fly correctly or any number of other Flight Simulator problems all I have to do is delete or rename the olecc.dll and that,"can solve all fs9 problems - freezeng, CTD's etc". Your words. As a example, I had a faulty AI texture that caused a CTD whenever it came into view, silly me I hunted down the texture and fixed it, when instead, if as you insist, I had removed the olecc.dll instead it would have fixed the CTD. To put it simply, you are painting a very broad stroke on a very small canvas with that claim. Posting links to support what you want to believe is fine and I do appreciate them but one should not stretch the implications by saying it is the magic fix for issues that can and often do have other origins.

 

Now can we please get back on topic and try to help Steve solve his problem, which most likely is not olecc.dll related to begin with?

I didn't say that is a magic fix, but it's a very important. You don't need to be ironic becouse you didn't heard about this, or you didn't found right things with google.

We are all here to share our experience and good practice. I feel right to give advices becouse i managed to have stable fs9 and fsx for a long time. And i learned from other experienced users, but i allways accepted and tried their advices, and after that decided if advice was good or not.

About Steve's problem, i posted some links above. To get stable PC and stable and nice FS9 and FSX you need time and study, or guides. There can be a plenty of reasons for his problem. But if everything is set like there, it's very unlikely that can happen. 

For example, that 100% CPU usage can be related to  Windows Media Player and Windows Media Network Sharing Services. In guides above is strongly recommended to disable Windows Media Network Sharing Services, so anyone who apply things from guides will not have the problem. Of course, there can be another reason, but they are covered too

 

 

I didn't say that is a magic fix, but it's a very important. You don't need to be ironic becouse you didn't heard about this, or you didn't found right things with google.

 

What I wrote was intended to polite sarcasm not irony.

 

There is no need to be condescending. It is nice that you have a stable FS9. Nice that you wish to help others. Nice that deleting your olecc.dll works for you. You, for the second time, ignored the context of what I wrote or mistranslated it to avoid my point. You wrote, "can solve all fs9 problems - freezeng, CTD's etc". That is simply not a accurate claim. That claim is what I am disputing not the benefits or lack thereof of deleting the olecc.dll. Believe it or not, I do know quite well how to use a search engine such as Google and I did, I just didn't find anything that supported the claim you made that I have quoted already several times, . . . . . possible benefits, yes, your claim, . . no.

 

If you feel the need to have the last word on this, then do so. That is your choice and I will not respond because it will not be of any benefit to anyone or serve any useful purpose.

 

Now, to try avoid any further strife I suggest we both just let this go. In your profile it appears that you are a Berliner? If that is correct we might very well be suffering from a language and translation difference that is making things seem worse that they really are. We both want to help others and that is what matters and what we should do.
