I can easily create a startup situation at OMDB with a default aircraft; VAS usage around 3.4 GB. It's all about the combination of addons, texture sizes and graphics settings you are running.

 

Don't blame a single aircraft (PMDG B777), but don't blame a single airport (LGTS) either.

I am quite sure I can generate an OOM at LGTS or any other airport for that matter... 4096x4096 clouded skies, LOD_Radius 8,5, PMDG 777, full blown AI traffic, etc etc... 

You can not expect to have an extensive scenery like LGTS and not seeing a VAS footprint. Like with all addons you have to keep your settings realistic.

As stated above, I am very, VERY impressed by the small VAS usage of this airport. Especially when comparing it to other airports like for instance FT CYUL or FB KIAD.

I picked this up last night. Flew in from the new Mega Oslo. No OOM.

 

My settings are near maxed, ASN, FTXGLOBAL, PMDG NGX ETC.

 

Can't fault this scenery, it makes another wonderful addition to all the Greece airports out there in the market.

 

Next flight will be Q400 from LGMK
