747 and 777 - Autocruise 8x results in NTDLL crash

Featured Replies

When flying either the 777 or 747 in 8x autocruise, I'm getting regular NTDLL crashes. 

Here's the general sequence of events:

1. Terrain textures start getting very blurry

2. The plane hits a turning waypoint, so it comes out of 8x and goes back to normal

3. I lose engine sounds, but cockpit ambient sounds like wind still remain. 

4. NTDLL crash:

Any ideas?

Likely that you're overloading the computer. Drop the max limit down.

Probably. It's just weird that it hasn't happened before until recently. I'm on a 8700k w/ a GTX 1080.

This suggests a driver or Win update causing it, then.

Yeah, I updated to that one and still see the same issue so I don't think it's the video card driver.

The ntdll as faulting module is always a hard one to track down.  The important thing to know is that this module is at the core of the operating system and it's very rare to find applications interacting at that primitive level so the search begins with drivers and other things that do belong there.  I've had issues with remnants of old drivers from NVidia causing problems that could only be solved when all NVidia files and folders are removed, and this must be done in windows safe mode.  Using DDU in safe mode is an easy way to accomplish this.  I have seen the ntdll pop up when couatl (scripting engine used by FSDT) acts up so make sure all things FSDT are updated.
