Out Of Memory in PMDG 777 Posted September 5, 2013 How in the world could you guys say this is PMDG's fault? Really? What is PMDG supposed to do, dumb down it's quality because you don't understand FSX? You really don't understand anything about OOM's, really, if you did, you would know that One single addon in FSX cannot cause an OOM. It's never the Addon's "fault", it's nobody's fault. The PMDG 777 probably was the one thing that pushed you to your 4GB limit, along with your sliders which are probably to high to begin with, with hundreds of addons stuffed into one area, it's no wonder you are having OOM's. So before you start blaming PMDG for you errors, check out what's really happening. You have to start making choices on what you load up in FSX, because it is unfortunately limited to 4GB.
