Okay, so this makes no sense at all. Yesterday I couldn't complete a flight of more than a few minutes out of Sante Fe NM, after a few minutes it would freeze up solid. This morning I flew from Santa Fe to Albuquereque and after landing on to Las Vegas NV. Not one freeze. What the ----? Took several hours. Next at bat, Aerosofts Tahiti X, around Tahiti proper and over to Moorea where I landed, no problems. Finally, flew out of and around Biggin Hill UK chasing a half dozen GA AI aircraft at sunset, again, no problem. Total time flying: from 7:30 AM to 1:00 PM, a few pauses to get more coffee... and offload coffee. While flying each of the hops I would change cloud settings, time of day settings, the plane, and views. Why no failure today? All graphic settings untouched and at ridiculously high settings and I made no in flight adjustments in frame lock, whether city or rural it was left at unlimited at all times with the Bufferpools addition to the CFG which has been there a few weeks.
The one and only thing I did do differently, I completely shut down the computer for a minute between the US, Tahiti, and UK flights. I always noted in Task Mgr that even that if I exited the FSX program and back to the desk top, after a few minutes physical memory use was still at 18% of total RAM instead of 14% on a cold restart. While it didn't sound like a lot to me I figured anythings worth a try.
Enough for now, my --- is gettin' sore. I'll see what tomorrow brings with 3 different locales and see what happens. Fickle doesn't quite convey it. Sheesh.
