About DX9-DX10-DX11-DX12

DirectX is an API (Application Programing Interface) used for developing video games and other such media applications, much like OpenGL.

The differences between DX9 and DX10 is that Anti-Aliasing is supported in DX10 and DX10 supports shader v4.0 Anti-Aliasing is used to smooth the edges of objects in a video game and makes little difference in games playing in low resolutions. With it on, it will noticeably slow down performance in certain games while delivering an almost unnoticeable difference in visuals.

The difference between DX10 and DX11 is that DX11 supports Tessellation. Hypothetically, DX11 is supposed to enhance performance with compatible systems as well as providing a graphics increase with a feature called tessellation.

DX11 is used with Windows7 and 8.1, DX12 is  Windows 10 only.
An example of the graphical improvements with tessellation on can be viewed here: (discontinued), tessellation is turned off at first. Too much tessellation can cause terrible lag just like too much anti-aliasing.
This video has nothing to do with flight simulation, but shows the differences with and without tessellation.

 Windows Update

Do I have to explain why? No. In Control Panel-System and Security-Windows Update you will find the frequently asked questions. Take care that you have always the latest updates for your Windows 7 system on board. If an update fails, don’t panic. Wait for another day or week and retry to update.

Do you have the right patches for every program (excl. FSX) ? An answer to that question is given by Secunia Software inspector (PSI). This piece of free-ware detects and installs missing security patches for your PC. The view shows an aggregated list of programs detected on your PC with the latest Secunia PSI scan. Get it HERE, install it and take advantage of it.

Now we getting somewhere…

Speed is all you need. Your registry is the place where it all is registered. What’s in a name. To keep this registry clean and up to date, clean daily ! Go here and when you’re there, pick at the same time the Defraggler program.

Defrag, defrag, defrag… One file that is dragging you down in speed is the pagefile.sys and new installed scenery and textures. You cannot defrag pagefile.sys when Windows is running. For that reason, when Defraggler is launched, goto Settings>> Boot time defrag and change into  Run Once. The next time when you reboot, pagefile.sys is defragged. Defrag at least weekly. Do not defrag SSD.

Now you’re settled and waiting the errors to come…read more Unstable system – Error Resolution

Moving Package Cache

In order to be able to repair an installed program, WINDOWS stores information in a folder called: C:/ProgramData/Package Cache
In one of more subfolders you will discover current or previous installation CAB files and the Prepar3D.msi.  Depending of previous installation you will find File folders in the C:/ProgramData/Package Cache/ that look like folder names as below and contain 10 GB each:



If you need space on your system SSD, you could move this content to another hard drive. How to move your existing Package Cache to another hard drive ?
(e.g. drive G:)

Read carefully and check each step:

  1. Navigate to the root of C:/ProgramData
  2. Select the folder e.g.: C:/ProgramData/Package Cache
  3. Press the key combination Ctrl+X to cut the folder Package Cache (folder changes into faded color)
  4. Navigate to the other drive that you want to move your Package Cache to
  5. Press the key combination Ctrl+V to paste the folder e.g. drive G:
  6. Check your new folder contents on G: and compare with C:
  7. Navigate back to the original folder e.g. C:ProgramDataPackage Cache
  8. Delete this folder Package Cache if still there
  9. Close all Windows Explorer views and Open the Command Mode as administrator (%windir%system32cmd.exe)which gives you C:WINDOWSsystem32
  10. Type in the command line (without quotes) “mklink /j”
    (mind the space after the letter k)
  11.  After typing mklink /j  hit the space bar once and type a double quote ”
  12. Directly after this double quote, type the original location of the Package Cache folder and close with a double quote “
  13. The command line looks so far like: mklink /j “C:/ProgramData/Package Cache”
  14. Hit the space bar once and type the new location of the Package Cache as on your new drive between double quotes.
  15. The command line looks like e.g. this:
  16. mklink /j “C:/ProgramData/Package Cache” “G:/Package Cache/”
  17. Mind the spaces! And then Hit ENTER
  18. Ready
  19. The mklink /j  command creates a directory junction between “Link” and “Target”
  20. This is what you read in the CMD mode:packagecache-2.JPG
