Hi:I've noticed that everytime I have the Terrain display enabled on the ND I will sooner or later get a CTOD, without it everything is fine. I have a i-7 950 with 12 gigs memory, 586 Invidia card, REX & ASE UTX enabled. Frame rates seem fine right up to the crash. Any ideas? Other than that I love the NGX.Lon Duncombe

Lon,I fly with terrain on for almost every single flight I've ever done in the NGX (and I imagine a lot of others do as well) - I know of no issue with the TERR mode causing CTDs.Is there an error message when this occurs? There's a lot of other things that can cause CTDs.

Hi Ryan, thanks for the response. Usually there is just a white 'flash' and everything freezes. If I click the screen the image whites out and the hourglass appears, and the message 'fsx is not responding' with the options wait and exit. Waiting doesn't work, I have to exit.Lon Duncombe
