Overall, FSX runs very well with no blurries and a consistent 35fps.However there are some microstutters from time to time.I have made some tweaks to the cfg.Can someone please advise on any further cfg tweaks to help resolve

When you find a solution tto microstutters please let us all know. You can throw all the money in the world at it!

So it is an inherent FSX problem with no solution?

So it is an inherent FSX problem with no solution?

More or less, but a litle bit more than a little bit less...

So, there is nothing that can alleviate this,with regards to hardware/other tweaks,etc?

VOver the years I have collected the various causes of stuttering in FSX and from this list you can see why it is almost impossible to solve:Stutter causesChipset driversWindows 7 OSNtdll.dll mismatchOverride application setting in nvidia Inspectorvsync no triple buffering not set at 60 fpsvsync periodAA/AF settingsIncorrect obsolete FFR settingsIllegal accesses and invalid page faults can result in a program crash and/or stutters ie Hard Page FaultsPF size and locationNo PFHardware + BIOS issuesHDD Lag too slowMismatch RAM/cpuOverclocking RAM incorrectly in SB systemRAM clock speeds voltages incorrect

Hardware memory errors caused by overclocking may corrupt pointers and make correct software fail and/or stuttering.

Capping my FPS at 36 and entering a value of 25,000,000 in BufferPools helped me alot.Maybe it will work for you also?

So, there is nothing that can alleviate this,with regards to hardware/other tweaks,etc?

No Dimi, It's not quite that bad, but it takes either top of the line equipment or lowered settings along with certain adjustments within FSX, or both. We are closer to flawless performance than we have ever been, but the emphasis is on "closer."Kind regards,

Thanks for your replies gentlemen!Like I said, everything is working well no ctd,no bsod and no blurries.Just those damn intermittent stutters!!

What is your hardware configuration?

bp=0 + 30fps internal limiter cured microstuttering on my system

What is your hardware configuration?

Well, I guess its good to know that it wasn't the kitchen sink.... or at least its not listed... LOL

:LMAO:Seriously, its frustrating to be able to play other games full on ,whereas FSX is so temperamental!!

HawkYes I needed to add the kitchen sink! :LMAO:PeterH
