Lately I have been experiencing and unusual problem with FS9, after I have been flying for one and one half hours to two hours I begin to lose my textures. It begins with a flashing of any text I have on the screen such as the longitude and latitude, air speed, altitude and wind direction and speed that is in the upper right corner of the screen. Then I loose all the texture in my VC followed by losing the instruments then all the airplane textures and finally all scenery textures. After trying to figure out why this is happening I discovered that if I pause the flight and go into FS9 options-display-hardware and lower my screen resolution from 1280x960 (which is what I usually fly with) to 1024x768 and then go back to the flight all my textures are back. The next time I get in FS9 to fly, my screen resolution is set still set a 1024x768 and after flying for about two hours I lose my textures and switch my screen resolution to 1280x960 and the textures are back. But that

Hi.Did you add any thing new to your system / configuration? Sounds like you get a Memory leak, Landclass configuration problem?Check your %FPS, does it go down to 3-4 FPS? If true, then either a background app. or a configuration may be the problem. FS tries to allocate as many resources as it can to the active tasks, when resources become unavailable, it scales down one thing at the time, a kind of poor A.I. TV

Thanks for responding. If it was a memory leak I would think it wouldn't happen on both of my FS9 installs. My second install of FS9 which is on my F drive has no addons, it is pure FS9. Also both install have the update. My FPS are consistently in the 20s.I think it has something to do with my video card. But I haven't a clue what it could be.John

Hi.What do you have running in the background? AV? TV

>Hi.>What do you have running in the background? AV? TVI use FSAuto start, so I only have the basic window's functions running in the background. Except for ASv6, but I don't use it when running my basic FS9 on my F drive.John
