FPS fluctuating at least 10-15fps - I thought this was normal

Recommended Posts

After seeing the latest video from Robert there is one thing I just noticed that I had never seen before in any of his videos, the fps held steady within a couple of fps. There must be something wrong with my settings or a background app that may be running as my fps set at unlimited settings are fluctuating at least 10-15fps as in 25 to 40 fps at all times even without any cloud coverage! I am not on Avsim often so I may have missed something about a tweak? I thought this issue was a normal problem we all may have!

 

Anyone have any ideas.

 

 

Specs:

Processor 4790K @ 4.6

 

RAM 16 GB 2133

 

EVGA Titan

 

Mother Board

ASUS MAXIMUS VII HERO Z97

Nick,

 

You'll need to provide more info ... 

 

1.  All your graphics settings (5 screens worth)

2.  Add-ons used (including aircraft)

3.  Weather/Location/Time

 

Typical process of diagnostics is to 

1.  Kill any tasks running the in background that aren't required for P3D

2.  Disable all DLL.XML and EXE.XML entries (just temporary for performance testing)

3.  Adjust graphics settings until you find consistent time between frames  (I use FRAPS to log time between frames and FPS)

 

Cheers, Rob.

Thank you for your time to help me, I will get the info you asked this Saturday. I have never used FRAPS, is this a free utility or a purchase?

What does Disable all DLL.XML and EXE.XML entries mean? And HOW?

Ron -

 

I was able to check my graphic settings and they were way off, reset them to your 4kbut I backed down the autogen 1 notch.

I killed all tasks running in the background

 

Success, 27-30fps constant.

I am now about to add the second titan for sli.

 

Thank you!

Glad you made progress.  

 

The DLL.XML and EXE.XML are located here:

 

C:\Users\YourUserAccountName\AppData\Roaming\Lockheed Martin\Prepar3D v2

 

(i.e. for me ... C:\Users\Rob\AppData\Roaming\Lockheed Martin\Prepar3D v2)

 

You can edit them with Notepad.

 

To disable an entry

 

<Launch.Addon>
    <Name>VAInterface</Name>
    <Disabled>False</Disabled>
    <Path>Modules\VAInterface.dll</Path>
    <DllStartName>module_init</DllStartName>
    <DllStopName>module_deinit</DllStopName>
  </Launch.Addon>
 
change to 
 
<Launch.Addon>
    <Name>VAInterface</Name>
    <Disabled>True</Disabled>
    <Path>Modules\VAInterface.dll</Path>
    <DllStartName>module_init</DllStartName>
    <DllStopName>module_deinit</DllStopName>
  </Launch.Addon>

 

or you can disable ALL entries:

 

<?xml version="1.0" encoding="Windows-1252"?>
<SimBase.Document Type="Launch" version="1,0">
  <Descr>Launch</Descr>
  <Filename>dll.xml</Filename>
  <Disabled>False</Disabled>
  <Launch.ManualLoad>False</Launch.ManualLoad>
 
change to
 
<?xml version="1.0" encoding="Windows-1252"?>
<SimBase.Document Type="Launch" version="1,0">
  <Descr>Launch</Descr>
  <Filename>dll.xml</Filename>
  <Disabled>True</Disabled>
  <Launch.ManualLoad>False</Launch.ManualLoad>
 
You can do the same process with the EXE.XML
 
NOTE: when you disable entries you lose functionality of products ... you ONLY do this for diagnostics when you are trying to resolve issues.  Suggest you backup the files first before editing them.  If you're NOT comfortable editing files, then don't.
 
Cheers, Rob.

Rob,

 

I would suggest setting manual load = True rather than disabling all the add-ons. Then the sim asks which add-ons one wants to either load or not load. Then one can test various add-on combinations from none to all without constantly editing the two XML files.

Hi Jay,

 

Good suggestion, but my DLL.XML and EXE.XML are lengthy ... and at my often too rapid a pace combined with my old age, I'll forget what I had or had not selected on the next iteration.

 

Cheers, Rob.
