Arnaud Claire might be a wel know name to you already. He is one of the most famous french freeware addon creator for FS.
Recently, he has released the beta version of his next project: a modification of the landclass used for the mountain areas, along with some specific textures. The result is a modification of some of the surfaces. The mountains textures are more varied, more similar to what they used to be in FS9 for example.
I have made some comparative screenshots to show you exactely what we are talking about. For each pair of screenshots, the first one is the default FSX, and the second one is with this new addon. The region is Switzerland, around Interlaken and Meiringen, with the freeware mesh from the c30s website ( http://c30s.alpes.gratisim.fr/ ).










I hope the screenshots are explicit enough. I didn't have enough time to test it so much, and I have flown only in the Alps for now. However, I can already say that I'm quite pleased with those modifications, the mountain areas definitely look more realistic.
You can download the addon on the c30s website:

Ah well, it seems that while I was typing this message, the website proposing the download has been disabled. I post my message anyway, perhaps the site will be enabled again later today. Just keep trying
