Need help getting rid of crackling sound during approach with MD-11

Featured Replies

Hi all,I really enjoy this aircraft.Lately I added several extra programs to get a better " flying" feeling.The total are : - ASA- VRI CDU- VRI MCP Combo- VRI Hat Track- Rex Clouds- UTX Eu- ST LandclassWhen doing an approach at dusk sound cracks start when deploying the flaps.Then they stay till I have landed.When being at taxi speed they are gone.I use the 182.50 NVidia driver as any driver higher than that one gives sound cracks from starting up FSX.All suggestions are welcome.

Sounds like a sound driver/hardware conflict/issue when your system is getting maxed out with the heavy add-on load. To confirm try running without ASA and VRI and see if that helps.

Setting a fairly large "Bufferpools=" config setting in the fsx.cfg has helped others with this problem.There's some discussion of this in Nick Needham's tweak guide, as well as here on the Avsim hardware forum.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

That was it !I amped the bufferpools up from already 100 to 400 and the cracks are gone :( It only worked with the latest 190.xx drivers. None of the 18X.000 above the 182.5 worked.Many thanks !
