1. To all with Amsterdam LC issues or other problems: Did you run the installer as admin?
I did it and haven't got those issues but forget to ran the Libraries as admin and nothing happened, so I uninstalled the old Libraries and then ran the installer of the new one as admin before installation of Amsterdam.
2. My settings aren't maxed out but eitherway more right with the HighTex installed and with planes like the PMDG 777 I haven't got OOMs with a VAS of about 2,3 GB (maximum) and I have FTX Global & Vector, HDR mode, GSX and FSGRW but no AI traffic except around 15% of road and sea traffic.
No idea why you have such problems, maybe you maxed out too much(?)
If anybody want to know my specs and settings then you welcome to ask
