Ok so I installed this a couple of nights ago. I have never had problems with Oom errors before this. I know it's not compatible with P3D but everything looks great and runs pretty good Fps wise. I use Active Sky next, Rex 4 Orbx Sak Orbx Open LC My Traffic 6 with Ga and airliners set at 20%. I moved my scenery and Autogen sliders to dense and my vegetation to dense. Still get Oom CTD. Also disabled photoreal scenery. Would like if some of you would post your settings for this addon. Thanks!

I have Anchorage X i P3D 2.5 with the exact same setup as you: Active Sky, Rex, Orbx SAK/LC, My Traffic 6. Traffic sliders are at 25% and all autogen sliders at Very Dense. I've never had an OOM error around Anchorage (or anywhere else in Orbx regions) with those settings :/

 

My best guess is that something other than the scenery is eating up memory.

Yes I was afraid of that. I am doing a complete reinstall of everything now. I started having problems with loading P3D.

Reinstalling software rarely solves a problem, trying figuring out what is causing a problem before creating new ones.
