I had my system running smoothly, even in FTX areas, and then POOF, I started getting OOM errors and now it is stuttering.  So I turned down the  TEXTURE_MAX_LOAD and LOD_RADIUS.  My frame rates in non FTX areas are erratic now too?    I no longer have the OOM errors but the stuttering is still with me?

 

The only thing I can remember changing was loading a shared REX4 Direct theme.  I have since returned to my original theme, but see no difference.

 

I checked to be sure my nvidia settings haven't changed, that my CPU was still running at he correct speed, DirectX10 Fixer was set the same and my fsx.cfg looked correct.

 

Any ideas where to look.

 

Thanks

I am currently in the process of reinstalling FSX and all of my addons. I started suffering from "hard stutters" (one second intervals) at large airports with lots of AI planes active (when this had not been evident before), and I finally became so annoyed with it that I decided to check to see if something had been "corrupted" in my FSX installation.

 

I can't be sure of what may have been the cause, but I am suspicious of the DX10 Fixer, or possibly ORBx stuff (since these were installed around the same time that the problems started to occur).

I too have done a recent fresh install.  It took me about a month to get most everything found, loaded updated and tweaked.  It has been running better than ever with almost everything maxed out after loading the DX10Fixer and related tweaks.  Ran super for the past few weeks and then BLAMO yesterday.

 

The last problem I had prior to this were with TrackIR and EZCA. I was having a problem with TrackIR using about 35% of system resources but found that loading it prior to plugging in my Saitek devices fixed that problem and then loading FSX.  Then I had a problem with EZCA creating StackHash errors and crashing FSX; can't remember what I did there but it only creates about 3 errors now while loading FSX and then the errors stop without any more impact.  But, like I said, they had been sorted and everything fine for a week or two now.

 

I am at a real loss at what has happened.  It is not really flyable anymore and after a month of research and pain, not to enjoyable.

Stuttering can be eliminated by making sure you have a page file on each HDD (system managed size) and, if you look in the AVSIM FSX Configuration Guide (link in my signature), the AA-Transparency setting will eliminate stuttering but it will use a lot of resources.  I did a new install of FSX a few months ago and, after flying out of BluePrint KIAD in any aircraft, I saw 1 second stutters.  Very annoying!  I eliminated it by placing a page file on the HDD's containing my scenery. Maybe it will work for you too.

 

Best regards,

Okay, thanks Jim, I will give it a try.  Curious why this problem just popped up though, if this is the problem.

 

Rick S.

Okay the Antialiasing Transparency Supersampling setting is at 8x Supersampling, been there and working fine for weeks now.

 

Trying to remember how to do the page file thingy.

 

Rick S.

Out of curiosity - what does transparency anti aliasing has to do with stuttering? 

 

Shimmering - ok I understand, but how does it influence stuttering? If it is eating more resources than it can only increase the stutters, or? 

Drive#1 C:\ (OS) 256GB SSD was 3,072MB min/max now 12,288MB min/max

Drive#2 D:\ (FSX) 512GB SSD was 0MB min/max now 12,288MB min/max

 

Off to see what that does.

Jim, thanks for this. I have a very smooth FSX in general, but this seems to be good for overal performance and it seems(i'm not 100% sure)that allmost eliminate that occasional stutter i had on a very bussy airports - Aerosoft EDDF with NGX for example.

 

I had paging file set only on OS drive, now i set this for all drives. I just read somewhere, this way OS will use page file from the less bussy drive, and that should improve performance. 

 

Nothing spectacular, but there is a difference

Dang B24, I made a huge change to my page files but I see no difference at all.  Glad Jim's comment helped you 

 

Jim, I thought I read somewhere that you should use a non-SSD drive for page files?  I do have a 1TB HDD for downloads etc.

 

I really don't see any change in the stuttering.  Maybe I should qualify my stuttering as jerkiness.  The ground seems to moves in 10 to 20 foot increments, if that makes any sense.

I know exactly what you are seeing.  I saw this a lot at FSDT KORD in my PMDG 737NGX and 777.  Do you have MyTrafficX or other AI program installed?  If you have MyTrafficX, open Manage Aircraft Config program and turn off Enable Exits for Ground Animation and Enable Light Effects; enable Use Simplified Aircraft and use models for wide screen.  This made a tremendous improvement for me and I honestly did not see bad looking AI (you have to look really close).

Did you change to system managed size for all drives?  Here's a good explanation of the page file - http://lifehacker.com/5426041/understanding-the-windows-pagefile-and-why-you-shouldnt-disable-it.  Of course there are many other "experts" who disagree but I have only seen a major performance boost.

Glad it's working for you Zeljko.  You're the one who has been teaching me the performance tricks so I'm happy to see it working, even slightly, for you too. 

 

Best regards,

Well, in this case, do you have AffinityMask tweak in your fsx.CFG? If not, add somewhere in fsx.CFG(where other section ends):

 

[JOBSCHEDULER]

AffinityMask=14 

 

This is for your quad core processor. If you have hyperthreading enabled, set affinity mask to 84

Thanks for this kind words. And yes, i tested it again. I think there was no too much space for fsx performance improvement on my system, this is why i see only slightly improved performance. But there is a difference, definitely

Never heard of it and I don't have any AI package that I am aware of.

I have 2 other SSD's Win7 OS and Win7 Programs; self descriptive and only used when booting Win7.  The last drive is a common shared storage 1TB HDD drive without a page file.

 

Should I be putting a pagefile on these?  What do you think about the size?  The recommendations I have seen are 1.5 times physical RAM.  I have 16GB.  That would be an awfully big pagefile wouldn't it?  Isn't the 12,288MB files I have now on C: and D: too big?  According to the article, maybe I should only have a pagefile on the common HDD; that would be easier on the SSD's.

 

Thanks

Hyperthreading off and YES, Affinity Mask=14.  Made a huge difference when I put that in, way back.

 

Thanks

My pagefile is set to 12262MB. I only have a single 2TB hard disk. AA Transparency is set to 2xSGSS, and I will test my system again once the basic addons have been installed. That may well be tomorrow.

Should I be putting a pagefile on these? What do you think about the size?

 

I have no recommendations as to whether you should turn the page file on for all your drives.  All I know is that having a system managed page file on every drive improved performance and the nasty 1 second stuttering when I flew out of BluePrint KIAD (versus nasty stuttering with a page file on only one drive).
