I think you misunderstood what I said. I was talking about the thread on the P3d forum, not this one. The staff here on orbx have been very helpful compared to the LM staff,

Wow we have done more progress here in 24h on this bug than in 6 months on the p3d forum where the staff seems to be ignoring the thread completely... So thumbs up for ORBX. Anywho, this is something I mentioned already on the other thread but not here which might be relevant: When initially troubleshooting this bug months ago I found forum threads describing this exact issue dating back to 2011 (!) So it seems to me that this is an issue at the core of the p3d/fsx engine. I'd also like to add that the Flightbeam scenery is no factor with this bug. for me the bug appears with both default and Fligthbeam installed. EDIT: Here is the earliest thread I could find made in 2011 https://www.avsim.com/forums/topic/355803-747x-slams-to-ground-short-final/

Hi, Im the user mentioned by @IncreaseVS on the initial post. And for clarification: The video and screenshot I made (and @IncreaseVS used here) were taken without any ORBX product installed since at the time I did not own any yet. The vertical wave thing is (for me at least) caused when the "Water Detail" slider is at High or Ultra (I cant remember) but I used to have them at airports like TNCM aswell so I believe this isnt ORBX related. (I have my slider at Medium and they dont appear). I havent experienced the grass on runway thing so idk about that but the "slam to ground" effect during flare seems to be a p3d native bug that happens to larger aircraft (I have only experienced it on the pmdg 777/747 and qualitywings 787) that approach sharp terrain edges (hence why its "fixed" with a texture res of >19m). On a forum thread I created half a year ago and that is still ongoing (http://www.prepar3d.com/forum/viewtopic.php?f=6314&t=131079&e=1&view=unread#unread) @IncreaseVS submitted the following observations: - default sim + large aircraft = slam bug - orbx global + vector + NA OpenLC + large aircraft = flawless - orbx global + vector + NA OpenLC + large aircraft + NORCAL = slam bug In his words "Perhaps one of the Orbx products fixes it, it just so happens that NorCal over-rides it back to default when enabled. " Could this be a thing? Please bare in mind that on my end at least this bug has plagued me for a year now and in the meantime I have changed PCs, wiped hard drives etc etc.. and the bug still follows me so I very much doubt its due to a simply remnant AFCAD file lying around somewhere or something simple like that.
