With working for a work-a-round, have found that the Map seems to be at fault here. When I view the map via topical view, there is less page files being accessed.
Also, with all my video settings set to the lowest available, slows down the eventual path of OOM error message.

Thank you for your time :)

update is from using my 780 at detected limits. Arma3 error had no code, but information is as follows : Out Of Memory Req:16384 kb Foot Print 3138387968 kb Pages 65536 kb.

Thank you

ps additional info, ran arma3 for 4 hours with no problem, but, as soon as I started to fly in helo... CRASH with following out of memory description:
Req: 16384KB, Foot Print 3175153664 kb, pages 65536.

notice the similarities???

I fly, I die, I ground, I am good.. WTF

Thanks
