Hi
Regarding the OOM in Prepar3d V2.4
I removed Aerosoft Night environment (UK, Germany, Greece, Benelux & Israel) and now the OOM vanished.
I use a Nvidia gtx 750 2gb, a xeon 3.06ghz in a z400 HP workstation, graphics are very good and high and frame rate set to unlimited.
I have installed UTX & FTX together with FSGLOBAL in EUROPE and fly with Qualitywings 757.
I don't use any extra airports
I hope it helps some of you guys
cheers
