Hello,Since sometime now am facing a flickering texture for all 3rd party addon airports & in some airports its happening only when am airborne nothing when on ground & only with the airport texture, hope someone will be able to assist in fixing this issue.Here are some examples:LPPR TropicalsimLHBP AerosoftGTX 260, driver v285.62RAM 6Go

It could be a conflict with another scenery addon for that area, most probably a mesh file.I do not have the Porto scenery but I do have the Budapest. Try this tweak:Flatten.0=495.0,N47 28.46,E19 13.42,N47 25.03,E19 18.88,N47 23.67,E19 16.89,N47 26.87,E19 11.29Paste the above line into your scenery.cfg at the end of your Budapest entry.

Thank you Rafal,It didnt work, am trying to find out the mesh that its causing this, this is weird because all 3rd party airports are affected payware or freeware.

No one is able to give assistance?

The only time this ever happened to me was with an older version of contrails pro.When active i'd get ground flicker everywhere. Don't suppose you're running that?

I think I do :( , will try do uninstall it & see what happen, or if you have any other solution?

Update to the new version which solves this problem now. V1.3 I believe.

yes the version 1.03 fixes the problem, thank you so much.

Glad to help.
