I've upgraded my graphic card, switched to DX10, apply the Steve fixer, got some tips on the Nvidia inspector setup. My FSX came back to a new life with all that VAS issues gone...that i've experienced before DX10. I have a better quality now, shadow effects are cool, i can fly any high end payware aircraft (PMDG, Captainsim, Majestic, Aerosoft, BlackBox, Ifly, etc...) you can throw using Taxi2gate sceneries without OOM, CTD, etc...
