Hi. I switched to p4d two months ago and wanted to get some of the orbx airports to my collection (lebb/lowi). But to be fair it messed up 99% of the rest of the world with the "aec" thing. For example at As's stuttgart if i turn it on there's a hill at the end of runway 7 and if i turn it off the airport goes underground(no patterns anymore). Since this is so problematic and neither the auto test or the manual zone setting (missing zones for the manual mode) work, did you guys got it at least to work or fully disable? Also i created another thread to be more precise rather than creating a question in a thread in which another question was asked. Btw my potato can easely run the game between 8 and 40 fps(c2q,6gigs of ddr3 and gtx 750ti).
