Wrong Version of UiAutomationCore.dll

Featured Replies

Just don't touch system files! 

 

Here is only about FSX root folder. you can check which version works better for you -  6.0.5840.16386 or 6.0.6001.18000. For me 6.0.5840.16386 works a way better, the other version gives me freezing, hanging and even worse performance in flight. But it's not same for everyone.

You can check 6.0.5840.16386, and if you don't like it or if you get some issues, revert back to 6.0.6001.18000. Restart PC after after dll replacement

Thanks, Oliver & Zeljko. Advice taken note of. Will stay as I currently am. Just confused as to why where I was getting relatively good FPS of around 22-27 FPS, now I'm down to 11-14 FPS in just thin blue FSX sky with ORBX weather, and at something like Aerosoft's CDG(Paris), I'm down to 7FPS.

Definitely not.  Just remove the Uiautomationcore.dll from your main fsx folder or put in the version you want.  Future installs of FSDT products will leave this part of the installation process alone.

 

Best regards,

Yes, so basically the older FSDT installs (which I have saved) will reinstall Uiautomationcore.dll (the version we don't want).

If one wants to try the 18000 version, were can you get it?

Nick's tuning thread has it. About 1/2 way down there is a link to download it.

I guessed you missed  the post  80 in this  thread by "Umberto"

Yes, sorry. I only check once per day.  :blush:

Well, in that case you are going to have to download the product again (the download is freely available to anyone).  I personally do not keep any of the FSDT installation programs on my HDD to save space plus, if I have to reinstall FSX, I want to have the latest version of the product.

 

Best regards,

If you own the PMDG 777, there's a link to it in the 777 Introduction Manual too.

 

Best regards,

Jim

I seriously can't believe that UiAutomationCore.dll is linked with smoothness in FSX, and stutters when the wrong version is used.

I can recall that the stutters appeared in my FSX few weeks ago, I probably installed something. I checked today the version, it was the wrong one.

Well, I don't know if anyone will attempt to convince you. It's you're system after all, and every single one is different no matter how similar.

 

But... suffice it to say that if the 64-bit library dll has to hunt and search for a 32-bit library file, it will take a varying amount of time based on a slew of variables.  But it will cause some type of delay, whether or not it's noticeable has to do with all the aforementioned variables.

 

In other words... it does!  LOL

I'm pretty sure about that now. I can fly now to some airports i avoided before(whith other dll), becouse of bad FPS and stutters - like Aerosoft EDDT, EDDK for example. Now i have steady 30FPS there even in bad weather. 

 

But you need to have well tuned FSX to notice that - clean DLL.XML(no leftovers), sounds to on-board audio or soundcard(not CPU processed), well tuned(balanced)Windows and FSX... etc. If you don't get a realy good performance in general, you can't see the difference.

 

 Like i said, i will try to make a video this days, when i have time becouse the difference Is so obvious on my system

My FSX is tuned to the max on my system. I get constant 30fps all the time, except with AXE and NGX in busy airports. I will test now a proper version of dll, I have an eye for stutters, I can tell easily is it better or same as before. B)

After doing some more testing definitely some crashes I was getting earlier are gone with this new UIAutomationcore.dll and the experience feels smoother in general.

Now, I don't know if this is because the right UIAutomationcore.dll actually improves things (other than menu crashes) or if it's because the old UIAutomationcore.dll was causing all those problems.

I agree fully.  I have stated in the past that I think the Uiautomationcore.dll provides a placebo effect.  You get a crash or freeze, place the Uiautomationcore.dll in your main fsx directory, restart fsx, and the crash/freeze goes away.  Yes!  The problem is fixed.  But, anytime you shutdown and reload fsx you are cleaning up your system (especially if you restart Windows too) and freeing up memory and you think the Uiautomationcore.dll fixed it for you.  You might get a freeze or crash a week later but it will usually go away if you simply restart FSX. 

 

I did see some smoothness between the 18000 version and the version I think is the correct one.  Most likely a placebo effect though as some of my subsequent flights were not so smooth.  For me it all depends on the weather.  Nice day, smooth.  Bad day, not so smooth.  I have now removed all versions from FSX.

 

Best regards,

Jim

I'm still not sure about less stutters with correct version. Tested it last night, didn't saw any difference. NGX perfomance was more smooth, I think....... naaaaah it is a placebo.

 

@Jim

 

I have few saved situations just for FSX perfomance testing purposes, so the weather and everything else is the same every time I load the situation, so the tests are probably legit. But who knows which proccesses were active during test 1, and which during test 2. So many variables can impact a perfomance in FSX, you can get different FPS in the same test situation every single time. FSX is one very sensitive piece of software, you must handle it with care, it's FRAGILE.
