HII am having a few issues with suttering.i have a i7 920 oc to 4ghz 6gb ram at 686 20 timings 1600mhz gskill. 2x1gb ati 5670 gigabyte radeons oced. 750gb hard drive for operating system and a 2tb WD 7200rpm for fsxissue is that i am having issues of running out of memory error and slight sttuers at major airports. i have used all of NICK N tweaks. And i have lots of addons leveld 767 pmdg 737 airbus x and lots of airportsfrom fsdreamteam and flytampa and aerosoft and ut2, utx and gex both europe and usa canada, rex overdrive etc etcnow i see i am using 75% of ram on win7 64bit enterpriserunning on a 46inch lcd philips tv 1920 by 1080 32 resolutionmy frames are locked at 30 using antilagfps are at 20 25 at major airportsfsx settings are mid range one more thing should i be running at default reso 1920 by 1080 x32 with my hardware? or is that too stressfull on gpu?can someone please help with this issue?thankyou.

I'll transfer this to a more appropriate forum for you :)

Your dual GPU setup could be at fault...stuttering is a pretty common side-effect in FSX with multi-GPU configurations. If it's possible to disable one card while running FSX, I'd try that and see if it helps.

HiThankyou for your replysAnd yes, tried just the 1 card, same problemThou ive noticed that i run task manager and have alot of unwanted processes running which may cause stutter issues the thing is which ones do i disable whithout doing any damage lolAny help will be greatly appreciatedthankyou

Make sure your antivirus isn't running a scan in the background, and turn off the file indexing service. Look for Nick Needham's setup guide for more specifics...like turning off file last access stamping. But even fully-tweaked, some stuttering is likely to persist. I have a fairly strong well-tuned system, and still see some occasional microstuttering at complex sceneries, especially when turning on the ground where scenery pans rapidly.

Okthankyou for your reply going try his nicks guide, thou i have just disable all on start up is that an issue? should i check them again?

which ones do i disable whithout doing any damage lol

You won't do any damage if you just quit the processes. You can quit them as you wish and test FSX. After reboot everything is going to be back.If you find the culprit, which I doubt, but still, if you do, then you can post it here and we'll discuss it.

Hi kostaThanks for replyOk so disabling most processes on start up running in background seems to be helping a little.but do not understand why it reverts back on rebootAnd i see fsx is only using just over 2gb of ram in task manager so leaves me baffled as to where the other 3.5 gb is going to.ive noticed that more ram helps out smoothing fsx? correct me if im wrong?

Uhhh.... after your post, I could write for many many hours about windows process management and why it happens etc.But I just want to keep this short, can't teach you windows in one afternoon.It reverts because processes are needed for various things. Each has some duty. If you turn them off randomly, you are likely to get into trouble with various windows functions.Generally, it's not going to help much removing processes, that much I can tell you, except if it's something that is causing problems (non-windows-third-party process usually).Windows starts them on reboot because it's set up to do that. And that's not a bad thing for windows processes.Third party is another story.FSX showing memory usage in task manager doesn't have much to do with anything useful.Shortly said, you should have min. of 4GB of RAM and optimally 8GB. Or 6GB if first gen i7.And a 64bit OS.

Thanks for quick reply kostaAhh i see make sense i guess.yep running 6gb of ram on i7 920 DO stepping win7 64bitoh well i guess this is th best i am going to get fsx running lolthanks for your help.

HiI have one more question, i would like to allocate more virtual ram. Should i added to E drive where my fsx located and has 2tb or on the C drive where the operating system is?And how much would i add for the 6gb ram is it 1.5 times?Thankyou

You shouldn't be adding anything. Either set system managed or disable virtual memory at all! With 6GB RAM you can definitely allow for that.

Let´s have a talk about pagefile, never seen that before!http://lifehacker.com/5426041/understanding-the-windows-pagefile-and-why-you-shouldnt-disable-it3072/3072 - it´s Da Gospel...

I agree with TOR you should never disable the paging file in windows as it is used by the the Physical RAM for quite a number of vital windows processes. If you want to find how big the paging file should be Google Mark Russinovich and Paging file and he will explain that you should base it on the highest commit charge/level of the physical RAM but all in all on a large drive up to twice the Physical RAM or let Windows handle it is not a bad bet.Myth: A large paging file slows the system down. No it doesn't in fact its the reverse - no paging file will definitely slow the system down. The paging file when set up does not affect system performance one way or another.To the OP what is the "Available RAM' figure in Task Manager when you say you are running out of memory?In fact you are probably not running out of physical RAM you are running out of or have a higly defragmented Virtual (Process) Address space which is limited to 4GB max for FSX and has little or nothing to do with physical RAM or the paging file (aka as virtual memory) See here:http://blogs.msdn.co...ress-space.aspxI may have a fix for the latter but it is in the early stages of testing, meanwhile you could use an 'autosave' function every several minutes or so which helps to refresh something in the VAS and again if you search these forums for autosave you should get some ideas on how to do it. FSUIPC4 I know has such a feature.OOM's are always going to be a part of FSX when you max things out, - it's just a limitation of a 32-bit piece of software.Hope you get it fixed.RegardsPeterH

Thankyou for all your replysstrange how i am using only 50% on idle then jumps to 95% when running fsx should i just buy new ram? say 3x 4 gb? or 3x8gb?i dont know im confused just know a little about computers sorry if i am going round in circles here available memory 2667mbcashed 2463total 6142 on idleforgot to mention that i also get short freezes for about a second constantlySo what number do i put in for page file and do i use E drive which fsx is installed 2TB or C drive where os is installed 750gb
