I am running FS9 with an AMD 2700, 1 gig of RAM, and an FX5200 video card. Kind of a low end system but it has been performing beautifully until yesterday when all of a sudden all of my scenery textures have hard edges. The system is no longer dithering between different landclass textures and instead of blending them they have sharp edges around the LOD cells for landclass. At first I suspected a file conflict since I have been heavily involved in the scenery project over at http://fs-freeflow.com/ . Does anyone have any suggestions? Do you think this sounds like a hardware problem and could a video card start doing that when some part of it fails? Thanks for any suggestions or things to try.

Hi Bob, I don't think what you're experiencing is hardware related. If your GPU would be going south, you'ld get screen corruption and similar symptoms. And frankly, I wouldn't have a clue how you could correct those annomalies. Nevertheless, it could be that you're asking too much from your combo in general? Another guess could be a modified '*.cfg' somewhere within the FS environment? Holger posted an interesting observation regarding DXT textures in the FFFL thread. Hope this adds to thoughts, good luck and kind regards Jaap

I am afraid that I am replying with some embarassment. I started thinking about the problem and the fact that it occured only a few days ago. What triggered that and what changes did I make to my system at that time? Other than loading and reloading the Freeflow Florida scenery that I am working on with Scott Gridly I could find no software anomalies. Then I decided to check the textures at various seasons as suggested by Scott. I discovered that only the summer season showed this texturing problem. That was a breakthrough clue because it told me that the problem was related to the texture set. I then remembered loading some custom scenery textures a long time ago and found I still had them in scenery/world/scenery/texture . Fortunately, I had the defaults neatly tucked away in a folder and put them back in and my problem disappeared. So, it was the first day of summer that triggered the problem and also provided a clue to find it. I am posting this to contribute to the forum body of knowledge in case someone else runs into the same thing.
