CTD on every flight...

Featured Replies

Since installing the latest patch, my sim crashes to desktop pretty much every single flight I take.

Annoyingly, it doesn't happen straight away, but usually about 30-45 mins into my flight...

I disabled the VFR map, are there any other known causes of this? My sim was running perfectly before this recent patch....

I had also random CTDs after flying for 30min or one hour or two hours and now I have found the solution:

The problem: a thing called TDR checker monitors the computer’s hardware, particularly the GPU. When the GPU stops responding with the computer for 2 seconds TDR checker restarts the driver. The TDR checker was good on paper but did not work in the real world as a GPU can stop responding when it is working hard.
Here is the solution that worked for me, it requires an extra sub key entry into the Windows registry, so please only implement if you feel OK with editing your registry!

  • Exit all Windows based programs,
  • Click on the Windows Start button, type regedit in the Search box,double-click regedit.exe from the results above.
    If you are prompted for an administrator password or confirmation, type the password or provide confirmation,
  • Browse to and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
  • On the Edit menu, click New, and select the QWORD (64-bit) value from the drop-down menu,
  • Type ‘TdrLevel’ as the Name and click Enter,
  • Double-click TdrLevel and set the value as 0 (it is set to that by default, but double check) and click OK,
  • Close the registry editor and restart your computer for the changes to take effect!

Make sure you create a Qword (64bit) key for Windows 64 bit OS and NOT a Bword (32 bit) key because that wil not give the right result.

The same solution fixed CTDs in Prepar3d for me. If you encounter CTDs again after a Windows update, please make sure that this key still exists in your registry!
It happened to me that the key vanished after a Windows Update.

Maybe this can help you

Dirk

 
 
 
 
 

What's the system specs?

we just had that very discussion, perhaps this helps:

60-130 fps. no CPU overclocking.

very nice.

I have the same. You should not have to do all sorts of work arounds. It is brutal. 

just avoid VFRmap. and

1) switch SOUNDS from AZURE ONLINE VOICE to WINDOWS OFFLINE

2) and don't use any Multiplayers, only AI or Real Traffic,

since I made these 2 changes, I had no more crashes ever since.

I literally can't complete 1 flight at the moment.

I punched your error code into Google, and it let me to this:
