Sorry if this have been asked before (I imagine that it has), but I'm too lazy / stupid to dig through the thousands of old posts to see if i can find a similar topic.I havent flown FS9 in years, however, I did a flight today, and after about 2 hours I got a popup telling me that FS9 had run out of memory. I have a 6 gb system. So, since FS9.exe is a 32 bit executable, do I have to patch it with Daniel Pistellis 4GB patch to be able to avoid OOM errors, or is this another issue altogether?-Wim

Wim,First, did you do the upgrade to FS 9.1?What is your OS?Do you have a high end video card with lots of memory ...some combination's (OS and memory switches + video card) could be a problem.What other software is running with MSFS (scenery etc)?

Yeah, I patched up to 9.1, I'm using a completely virgin FS9 installation except for the iFly 737, and some 40 AI packages from World of AI. I got a 768mb gfx card, i7@ 3.8ghz on W7 64. Flying online on VATSIM, so the traffic shouldnt use much memory at all.
