I highly appreciate if you want to help me, but then, please read the whole post! Just to prevent you guys from asking questions that I've already answered in this post. :) Thanks!Hello captains,Around 1 month ago, I have bought a new graphics card. EVGA GTX 560Ti-448 Classified, this is not a regular GTX 560Ti, but one with 448 shader units instead of 384. I have now sold the card, because I highly regret that I bought it for several reasons:- I have many stutters in FSX, which I'm not sure are caused by my new graphics card- It's only limited to the newest drivers (285.xx or later). So this means, I'm not able to install the extremely stable 275.33 WHQL drivers.- It's a card that's only temporarily sold in my country. So if I want to get another one to put in SLI in the future, this will be a hard task to find one.- After having heard PMDG developing for XPlane 10 from now on, I prefer having the best of the best, for the future.I'm planning to upgrade to a GTX 580. It's most likely gonna be an EVGA GTX 580 DS Superclocked 1536MB. Seems like a good choice to me. :) Please note, I do NOT have this card yet, perhaps this will solve all my problems.So, let's get to the point now.Since I got my new graphics card, I've been having lots of little lags and stutters in FSX. At that time, I still had my 5400 RPM Caviar Green, and I thought it was all caused by that slow HDD. So I now got my SSD, as you can see in my system specs. After having installed it, it definately reduced the stutter problem, but did not eliminate it by far.I will now try to explain my problem. (Right under this post is a demonstration video, please note that due to Fraps recording, the stutters became worse than they actually are, but it's quite comparable).My problem is basically, that I'm seeing lots of little small lags and stutters all the time. They happen every few seconds. These are not long stutters, or small lockups, these are continuously happening hiccups. EDIT: my stutters do not happen non-recourse heavy airplanes like from Carenado, or the default planes. It happens mainly in recourse heavy airplanes like PMDG NGX, and MD-11. No stutters around the sea and at cruising altitude. Only above land, happens both at urban and non-urban areas. Although it happens slightly more at urban areas.Here is what I tried to solve the problem but did not fix it;-Bojote's tweaking tool. Have been using this for a long time.-I've tried all kinds of different FSX.cfg settings myself. TEXTURE_MAX_LOAD=4096, TEXTURE_BANDWIDTH_MULT=40, 60, 120, tried it all. BUFFERPOOLS, with RejectThreshold=131072 // 262144, PoolSize is 8MB (can't remember the exact number but tried it). I know that it's not recommended to have PoolSize=0 in there with a system that I have, because it's causing instability (that's what they say, but I don't notice any instability... perhaps I'm being to naive though lol). I always find that PoolSize=0 gives me the best results in terms of framerates, and stutters. AffinityMask=14, HIGHMEMFIX=1, all that stuff. Frame rates are great (mid 30's, sometimes even above 50).-Tried FPS limiter, with 30, 35, 40, 50 fps, everything. I always find that 40 gives me the best results.-Did Ryan's Inspector guide with all the correct settings. I find that 32xAA (the highest setting), reduces the stutters the most, but reduces framerates a little.-Tried removing the overclock. My overclock is tested for stability using Prime95. I ran a Large FFT test for 12 hours with no errors. I'm also not having any BSOD's.-Tried swapping the RAM sticks, so this means I can rule out the RAM for now, right?-Tried all kinds of FSX settings, without light bloom, LOW 2X water, no traffic, medium autogen and all that.What I suspect what the problem is:I've read several stories on this forum, that the newer NVIDIA drivers are causing stutters in FSX. Well, unfortunately my card is limited to the newest drivers, so I can't try any older ones than 285.xx.Or perhaps it's some kind of incompatibility issue with FSX and the GTX 560Ti-448. It's a very new card, released around 3 months ago.After having done research in the MS FSX forum, I got helped by a very helpful guy called DJose. He told me, that he had the same mobo as me, the Asus P8Z68-V Pro. He told me that he had exactly the same problem as me, and he had also many CTDs (which I'm not really having, --- knocking on wood ---). He told me, that it's a very unstable board, and after he replaced it with an MSI P67-GD65, that his problems were gone. So what I'm wondering now, whether he's just right, or is the fact that his problems are fixed just caused by coincedence, because he reinstalled everything. The second thing seems unlikely, because my Windows installation is only 2 weeks old. So I also reinstalled everything.My question to the PC/FSX guru's here is, if you know what's causing my problems. Am I simply being to perceptive, or might the problem be one of my hardware components. And if so, is there a way I can find out what's causing all this?I REALLY REALLY hope you can help me. I have my fingers crossed, that when I have my 580, that all problems are will be gone. But yeah, I'm not sure about this.Thanks for helping me,Arjen

So did you setup your PC and FSX according to this advise, which I gave you previously?http://www.simforums...187.html#198187DO AS INSTRUCTED, and save all the posting and the subsequent headaches with all the different suggestions you´ll get.Nick´s guide is a must have basic, EVEN Bojotes Tool comes after that, IMO...PS: I doubt that a mobo can be a main source for stutters in FSX, I have the Asus P8Z68-V, no problems at all.

What AV are you using?What is your FPS set at in FSX?

MS Security Essentials, tried deleting it, didn't work.Tried limiting in FSX did not really make a difference. Setting 40 in Inspector and Unlimited in FSX still gives me the least stutters.

Do you have the file indexing service disabled?If you run the task manager and look in the processes tab, are there any processes with CPU utilization spikes that synch up with your stutters?Your description of the problem suggests something related to autogen...if you drop to "Sparse" does it help?

1. Make sure you have the latest BIOS and System Drivers for your MB
2. Make sure your Windows Update is enabled to get he latest MSVC and .NET Runtimes
3. Make sure MS Essentials AV Real-Time Protection is turned off
4. Your HDD is slow: 5,400 rpm is slow (ned 7,200 minimum), and also the Green series is the slowest of the series with the smallest cache, so get Caviar Black 7,200 RPM with 64 MBy cache as the minimum HDD.

Cheers,- jahman.

Probably not the hardware. AI traffic density, HD cloud textures etc.

Spend hours and hours setting up his guide and did not make a difference whatsoever. I don't see what the point is of setting this guide up, cuz it doesn't do anything for me at least... And I already had most of the settings anyway.

All have this of course, and I have no HDD, I have FSX on an SSD as i said in my original post.This is what I just found: When I put both autogen sliders to 0, there is no stutter whatsoever, then, FSX runs smooth as silk. But of course you always want autogen. So what does autogen rely on? Graphics card? CPU? HDD? RAM?

All of the above.

All of the above.

Well I have an SSD, good RAM, overclocked stable CPU. I hope that a GTX 580 will eliminate the problem for me...

"both autogen sliders"???There's only one AG slider.

Best advise?Turn down your settings, and when the stutters stop, keep´em there! ^_^Oh BTW, your RAM is slow, get lat. 6 or 7...

They stop when I turn the autogen sliders off. Keep them there? No, I'm just about to give up on FSX. It just never works.RAM slow? What do you mean lat. 6 or 7? Please give a recommendation a good RAM set! Could my RAM cause the stutters you think?

Hold on with such statement "it just never works" - I have to state just the opposite, it always works. It's quite a fiddly platform, yes, but it works with all 200GB of data in it. And that quite well.GTX580 is a really powerful card. It can basically push anything you give it - at least until you go really crazy AI on the card as I or some others do (dazz for instance).Beside that, I think everyone is perceiving stutters differently. What for you are stutters is maybe for me acceptable, that is why it's very very hard to find what you're looking for.I accepted some stutters with FSX - until we can have 60fps locked without a frame dropping below it, we're going to have stutters. Unfortunately it's like that below monitor refreshrate.Could you make a video of your problem? But with an external camera? I hope you have a digicam or an iphone, or even a videocamera. Just put it on a small stand in front of the monitor to record correctly.That way we'll be able to see your exact problem and everyone can comment if that's normal or not.Right now, it's very hard to see what you're seeing.Oh and btw for me: 285.62, no other, locked 30fps in fsx, no external limiter. Anything else stutters.

Thanks Word Not Allowed, I will do this as soon as I can. About the GTX 580, do you think this might also reduce stutters in comparison to my GTX 560Ti-448? I know it will do something to FPS compared to this card, but not that much. What I care about at the moment are that my stutters are gone. Word Not Allowed, I know you are a very clever person when it comes to PC's. If you look at my system specs now. Is there anything you think of, which is a bottleneck of my system, or which is simply junk hardware, or which is simply too slow to run FSX.And I think you're also right. We all have different opinions, and perhaps, I'm being too perceptive. But when seeing other games, I know how smooth a game can run. So FSX looks so bad compared to it. My framerates are very very good, around 30 is the mininum. But, with stutters, a good framerate is useless...Uploading a vid as soon as I can....
