Anti CTD vaccine

[Emerson67 248]

This post is for all desesperados,

This is a nice tweak (actually not new) that should prevent a pretty common MSFS crash to desktop cause, by adjusting some Windows 10 GPU scheduler timeouts.

It does not prevent some CTDs caused by MSFS internal bugs, because this tweak acts on Windows 10 itself.

Procedure:

1. Open a plain text editor, like Microsoft Notepad (Windows accessories->Notepad) or Notepad++.

2. Copy and paste the following text into the editor:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers]
"TdrDelay"=dword:0000000a
"TdrDdiDelay"=dword:00000019

3. Save as "vaccine.reg" file, and close the editor.

4. Double click on "vaccine.reg" file, and then choose "Yes".

5. Restart the computer.

6. Run MSFS.

7. Give feedback.

 

What this tweak does? It increases (5 times) the values of two Windows 10 GPU scheduler timeout parameters.

You may tweak yourself those values as you wish. Here is the technical info.

Interesting - thanks! 

I am investigating this.  I am hoping it might help the 0x05 error, which is difficult to trace.

It might also explain why people with very powerful GPU's (3080 / 3090 etc.) don't get the error as much.

I just need to look up the default values in case I want to put it back.

I've had this mod running since last Thursday and have now completed four, two hour+ flights in the A320Neo with the FBW mod without a CTD. 

I can't say 100% that this has fixed the CTDs as I also reduced the AI% down to 40% and deleted the rolling cache at the same time. And four flights is not conclusive evidence. I could of course, reverse the above and restest and see if the CTDs return, but that's not going to happen !

However, so far, so good...

Before I had plenty of CDT on almost every flight and this tdrDelay and TdrDdidelay tweak solved everything! I put the 2 to 60 ...

It was your posting in another thread I that put me onto it - many thanks!

Using this fix since months - initially to avoid crashes in P3DV5.1 (Nvidia RTX 2080). And I never had a CTD in MSFS either. Highly recommend!

So by just clicking on this file after you create it, this entry is then added to the registry in the proper place, without having to edit the registry?

Thanks for this - I'm hoping this will mean I can start using a AMD driver newer than last Octobers.

yes, as long as you name the file with .reg on the end, it will automatically enter it into the Windows Registry when you double click on it - there will be a confirmation warning of what it is about to do. 

Then, for it to take effect, restart the computer (not shut down and start up - as on some PC's it will fast load a previous state and not change anything).

I have now done this and I look forward to testing it.  I have a few hours planned in MSFS this evening.

Thanks.  Will apply this.  However. With each registry patch like this should there also be an "antidote.reg" file to put Windows back to the previous state?

Just checking my registry the entries don't already exists so if I remember my registry hacking correctly in that case you'd want a file like

 

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers]

"TdrDelay"=-

TdrDdiDelay"=-

 

[sauviat 137]

@fppilot Would like to know how to reverse it?

Doing a search of the Win10 registry tells me neither of these keys exist at this location (nor anywhere else.)

In other words you're ADDING these keys, not changing them.

YMMV

That's my script for deleting them if you've added them with the original script.

I found the same thing. So to reverse it, I guess you would just have to remove the entry in the registry. ( Just a guess not sure) Or would that cause a problem if you just deleted the entry?
