Todd, I am running Windows 7 64-bit. I recently upgraded from XP 32-bit, which had the same issue. Opa, I know atleast 6 people who own this, and all 6 have the out of memory crashes frequently. I just dont understand what it is really, its not a specific area it crashes in, its just random places at random times.

There were posts about the Portland CTD being reported on the FlightZone forum, but that forum no longer exists. They never did find a fix to it as far as I am aware and then they went and abandoned the market or joined FSDT or something to that effect. I suffer from this CTD as well, on three OS's and 5 different machines - no common denominators, there is a bug internal to the scenery. I fly in the Portland area almost daily and the CTD is like a lottery, weeks can pass before you get one and then you'll have 4 or 5 in a row.

Guess I am one of the lucky ones then. I "fly" in or out of KPDX at least twice a week and have been doing so for over two years with nary a problem.

While I don't have any ctds around Portland I do get quite a pregnant pause as I approach within a certain distance of the area. Maybe 2 - 3 seconds. And then when I am near the upgraded airports, say I'm in the pattern or may be a bit farther away and I look away from the airport for ten seconds or so and then look back, the grounds are all plain gray then the texture will pop back in. It will do it over and over. To me it's distracting. Plus the airport background bitmaps are so much higher resolution than the surounding area that I find that a bit distracting too. Beautiful, no question but still distracting. So I'm going to experiment with reducing the resolution of the airport background bitmaps to 512x512 and see how it works. They are currently 1024x1024 and 1.33 mb each and every airport has at least five of them.Cheers..................Todd
