Thanks but have tried all these tweaks. at mo have dialled back autogen and traffic is at 23%, no road vehs. At EGLL in NGX strangely when pan round cockpit with mouse it is much smoother than with hat switch on joystick. haven't tried TrackIR yet. Just saw nirvana at EGCC when did a bank in the microlight and frames hit 60, smooth as butter, but when dropped below this microstutters appeared. As others have said its linked to the screen refresh rate of 60Hz

http://forum.aerosof...-you-might-not/ Try this. Follow it. Don't try thinking "my system can handle more than that" just set your FSX settings exactly like that, then slowly increase them till you find the point where you see a performance hit. Increase autogen and traffic last.

The microstutters have absolutely NOTHING (let me repeat: NOTHING!) to do with (too) high settings. I tried utterly low settings and still get stutters. In fact, just now (before I pressed POST to post this reply) I started FSX and set ALL (and I mean ALL!) sliders to the COMPLETE left, apart from autogen at SPARSE. Result: still those microstutters... (and awful scenery... ) My pc should be capable enough of running FSX with ALL settings off and without any stutters, I should think... So how can I slowly increase settings till I find a point where I see a performance hit if there is a problem right from the start? Overall performance is awesome, but it's spoiled by those microstutters. I can see when performance gets a hit, like above PNW Seattle or Portland. But then fps goes down etc. But the microstutter problem is there no matter how good or bad the performance is. I just thought that maybe it's a monitor thing... Everyone who has microstutters: what monitor do you have? I have a Samsung P2770FH 27" 1080p screen.

I get some stuttering too and have tried most everything I care to. No answer here just chimming in so the OP and others know they are not alone. Best setup I have now is internal locked at 60. Do not get me wrong, I do not have those big long stuters just some very minor occasional stuttering. Had it on my old rig Qx6700, have it now though greatly diminished.

By now I think everyone has those microstutters, but not everyone cares about them or sees them, as I said earlier... I really think it's something that cant be solved no matter what. Yesterday I even did the entire NickN routine (tweaking the system and FSX) and it made no difference at ALL. I am 99% sure everyone has those microstutters but not everyone gets annoyed by them. Nowadays hardware is good enough to run FSX well without having to tweak the OS etc. I've been testing and tweaking way too long now and in the meantime my system has become a mess (specially after doing NickN's routine), so the coming week I am going to install everything all over again: by now I know what to install and what not to install (when it comes to drivers, hardware, settings, tweaks, etc.) and then I am going to enjoy FSX as it is. Period. I think.

Amazingly uninspiring to spend lots of money and time, and still experience this! And yet there are folks who seem to have microstutters for the most part, solved. I'm one of those. I only experience non-silky flight when I'm in over my head as it were, as in running the NGX around areas of intense scenery density. I am of the belief you are best off if: 1. You have the raw horsepower, which you all most certainly do, at least compared to what I'm running.2. You are blessed w/ the correct combination of variables that happen to work well together to minimize conflicts, for lack of a better word. I think I have #2 dialed in, and #1 is a little marginal by today's standards. I guess one possible approach: search for someone who has demonstrated excellence in both of these, and copy them exactly, with regard to both hardware & software! Noel

The problem with that approach is that I do not believe there is anyone that does not experience the phenomenon. Those that claim not to are either not running the same combination of pay- ware and scenery and all other identical parameters to those that experience the issue and or those claiming they do not have micro stutters are impervious to the phenomenon or lack understanding of what the issue is. I think really the issue is inherent to FSX itself and still amaze myself that I even try to chase this antiquated program around worrying about it.

I feel your pain. I upgraded to an i5 2500K (@4.5), GTX580, 8 GB 1600 Mhz CL8 RAM and Windows and FSX on a seperate SSD. I came from a i7 920 @ 3.3, GTX285 and 4 GB 1333 Mhz CL9 RAM and WIndows and FSX together on an SSD. After spending all that money, I ended up using the same setings as on the older pc and as a bonus I have... microstutters... Performance is better in PNW Seattle or when landing the 737NGX on Aerosoft EHAM, but not as much as I hoped...! It's a huge disappointment, really. I do have the graphic sliders almost maxed out, but I also had that one my old pc and I don't feel like turning things DOWN after spending all that money. And btw I had to tweak my cfg even MORE than on my old pc to get where I am now. During my testing I found out the microstutters had the same frequency as the tearing I see with vsync off and I posted a topic about that. Just as you I think there is a relation. However, I've found no solution... Sometimes I really hate computers. P.S. I used bojote's tweaker and I also use antilag: without those it would be an even bigger mess.

Hi Jeroem, I am really sorry to hear that you are plagued with the micro stutter curse. Honestly, I really don't have them with my machine, and haven't since setting up my SB system a few months ago. All I can tell you is to not lose heart, for there is hope. I am not sure what would be different in my system than in yours since there are scant hardware variations, but then again my maxed out FSX programs are highly modified with changes I have learned over the years, mostly from others. Sorry I can't jump in and spend much time to make detailed suggestions right now. Real life is taking priority over my FSX hobby these days, but I have checked in here from time to time to see what is going on. Don't give up, for Sandy Bridge really does scratch the FSX itch. Kind regards,

Thanks, Stephen, for taking the time to post. Coincidently, and honestly, I am not kidding, I was thinking yesterday where you were and how you were doing because I missed your posts and input lately...! (I really hope life is not making it too hard for you...). Funny though, yesterday I accepted that microstutters are a part of FSX and I settled for lower settings (even lower than on my old pc) and there you are, saying it IS possible to get rid of microstutters...! O boy, now I am in doubt again, hahaha! But I've tried everything you can do and nothing helps so... I will try to simply enjoy what I've got right now... Nevertheless, I will search for some old post of you from the days you were setting up your SB-system (which in the end led me to getting an SB system myself): maybe I can find some golden nuggets in there. ;) All the best to you!

Gary, I think you are right. I have had 3 machines running FSX now and each and every one of them has (what I consider to be) microstutters. They are barely noticable but they are there none the less. IMO, the definition of a microstutter is looking down towards the ground from the left hand seat and every 10 seconds or so there is a tiny pause, almost as the scenery loads. When I say tiny, I mean tiny. You would not notice unless you were specifically looking for it. I have tried various CAS latency RAM (no difference at all), pushing the OC higher and reduced settiings. Zero effect. Of course my definition of a microstutter may not match with other peoples. Its difficult to judge without a solid baseline. One setting that seems to reduce (not eliminate) is forcing vsync through the driver.

I don't know Gary, because I am one of them that does not experience that phenomenon. Look at the software I am running. I understand what microstutters are and have experienced them previously, but not now, unless as I say I'm running more than the machine is capable of, which at that point becomes a case of the entire sim gettting not only low in raw frame rate but also just generally more prone to herky jerky behavior. I don't think there is anything necessary about having freedom from microstutters scaling uniformly w/ poor frame rate, such that you only see the impact of overdoing it by steady low frame rate. With most of what I run it is indeed silky smooth, even when taxiing. Here's a situation I experience: when I run frames locked at 30 w/ an ext limiter, airport ground traffic move herky jerky. If I hit F11 and dial back the lock to 26, the herky jerky mostly disappears, pointing perhaps to some timing issues not solved by higher frame rate alone. It could be what you are sensing is a tendency for most folks to run things higher than their machine can handle while maintaining freedom from microstutters. Maybe a little bit of a sense of entitlement since they have the raw processing power to handle it. Out come the 1080p resolution and all that that entails, maxing out all settings etc. Be fun to see if Flight is more efficient and less timing sensitive, or whatever it is that makes FSX setup fickle at best.

Hi Noel, nah, I am not maxed out with sliders to the right. I am setup per NickN, although I have tried Bjote's tool as well. Microstutters as defined by Glenn above. PMDG MD11, cloud9, ASE and Genesis come into cyyz at 160kts and stare at the ground on approach through the left window. I see ever so slight and occasional jitters (stutters). I have seen every uTube video of every guy with a tweaked system upwards of 5.5GHz ever posted and I can these stutters in everyone. Some people just do not notice them, I am sensitive to the issue now and can see them.

I define it the same Glenn, maybe it is our eyeballs that are jittery? I drink a lot of coffee.

OK, well I guess I have to look a little closer and maybe I will see what you are referring to. I know if it's there I'm obviously not focused on it. There are certainly lots of potential types/causes of stutters, but the one you refer to I'll have to see if I can concur. Do you have very fluid flight but with some stutters every 10 seconds or so? Are you thinking maybe this happens to folks on lower end systems as well, or more w/ folks w/ hardware like your own? If it's the former, then this sounds like something inherent in some part of FSX software that happens no matter what hardware/software as you may be suggesting, but perhaps is more visible w/ machines fully capable of overpowering other forms of 'stutter'. If what you are saying is true, for some who are sensitive to or suffering from this issue, the only work around will be Flight, or perhaps X Plane 10. One reason I may not notice this is that I typically fly at dawn/dusk which may mask imperfections better.

Don't know if this has been said here already as I haven't been following. A lot of stutters are caused by the monitor and v-sync. Basically, if you have a 60Hz monitor, you need to run FSX at 60FPS locked for it to be perfectly fluid. Anything below that you will see stutters. If you force v-sync off, these stutters are actually tears. Having v-sync on skips the frame that is torn, causing a stutter. The closer the FSX FPS is to your monitors refresh rate, the less stutters you get. For example, my laptop has a 60Hz monitor. I run the NGX cruising between 20-28FPS. Being quite far from 60, I get quite a lot of stutters. Now someone with a i7-2600K might run the NGX in cruise at around 45+. They're going to get a lot less stutters than me. Obviously the frames drop as we enter an area of dense traffic and scenery, ie approach to an airport. As our frames drop, we get further from 60, we get more stutters.

I would not look for it Noel, it is a curse best left undiscovered. I get pretty smooth flight and at times I see these little hesitations. Sometimes worse I think, when there are certain types of clouds. I had it before on my Qx6700 but much more pronounced. I really gave up diagnosing it, I tried a lot of things including diabling scenery, different drivers e.t.c. It doesn't bug me that much I actually never really noticed them before until a bunch of folks complained. Stare outthe window they said at the ground 300ft 160kts, and I did. Bad mistake.

Thxs Di, I have it looked at my resfresh rate 60 and it is the best it has ever been. Tried internal and external, different drives, single drives, raid drives, this is my second computer that has had the same issue. tried everything.
