Thanks for the input Paul, it was something affecting FSX from outside. It was finger trouble at my end! See my last post.

 

Very glad to hear it. It's always the simple things that get you...still 3.9GB is pretty savage. I don't think I've ever even hit half that.  I'm glad I decided against buying Orbx SoCal. UTX with Orbx Global will do fine.

Well, I had similar experience and disappointments when I got new "stronger" PC.....

 

I couldn't believe that, with stronger machine, FSX will "eat" all memory! I could not make one HR in the air without a beep. Little by little I started lowering everything, not much but enough to get me going. What really helped me at the end is new upgrade of Steve DX10 fixer, and tweak that I was afraid to implement before. I changed in fsx.cfg frame rate to 0 and unlimited in FSX set up, bufferpools at 0 (not sure about that), but even with strong PC (relatively speaking), my AM is now at 14. And I remember it was 84?! So how that got changed I have no idea. In order to have frame limiter to unlimited I had to change in NVIDIA config frame rate to 60. I picked that from Mats video I watched recently.

 

Since that last fix it is all like silk! I am afraid to sneeze around my PC being afraid something is going to change. I have installed CYYZ from Fly Tampa, which is arguably heaviest scenery on the market ever and I was unable to land on that APT ever since I bought it, but now with everything turned on (heavy sceneries, AI TFC, ASN, ORBX, ORBX HD APTS, PMGD 777) I am at max 2.8 GB. Touch shaky there, but managed to land last night with heavy snow and all lights on. Not sure if I did anything differently but perhaps worth trying.

AVSIM has a FSX Configuration Guide which talks about tweaks and has settings that work for many (at least for me there is no AA jagged issues on aircrafts).  See my signature for a link to the guide.  I do not recommend any tweaks especially if you have a powerful system.  With your current settings I'm positive you will eventually have issues.  It all depends on your flight plan and what you are flying, the eye-candy scenery and the weather.  If you have 2.8GB's of VAS that's great but it will decrease depending on the scenario.  Then it will give you more VAS as you are flying and then it will decrease again as you are arriving at your destination.  The arrival is the most precarious and the longer the flight the more likely you will run out of VAS.

 

Best regards,
