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

I am starting to think what we call 'microstutters' is NOT what people in this thread are referring to. They are obviously talking about something more obvious.

http://forum.avsim.n...ading-stutters/ Check out this thread. I had some issues with microstutters on a i7 2720qm but I eliminated them by reading this thread and coming up with some of my own solutions. It seems the hdd is the "weak" link in my system(I don't think its that weak it's a 7200rpm drive) but using ramdisk did help immensely. When FSX needs to read a file it has to read them off your HDD causing a very small(but noticeble if you're expecting a perfect performance from your new computer) microstutter but putting the most used files directly into your RAM eliminates this. Those of you that have an SSD this probably won't help that much, in fact you probably aren't experiencing this at all. Also I would only try this if you have 6GB of RAM or more. Also this is NOT a magic bullet for a "weak" computer.

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.

It seems what Glenn and Gary are referring to is something fairly specific. I took a test flight and looked closely to see what I think they are referring to, and indeed if I look fairly close to the plane I can see a tiny little almost shudder that last maybe a second or so, then disappears for another 10 seconds or so, and is recurrent. If what you are saying here re locking frames to match monitor refresh rate has credence, it would appear the pathway for 'totally fluid' flight all the time would be to DIAL BACK fsx.cfg settings, video driver settings, etc etc until you can always (at least for a specific flight scenario) maintain frames at 60 in any part of a flight. One could create batch files to load different fsx.cfg's for different flights depending on processing demand, and approach it from that angle. I'll have to test it and setup an easy to process scenario, lock it at 60, and see if this little issues disappears.

Fascinating, I took off in easy to process St George, UTAH in the old Cessna 441 Conquest, dialed up 60fps on the ext limiter, and voila the subtle recurrent brief jitter is completely gone. I was able to run the Turbine Duke locked at 60 there too and same same. Texture would load up as i was flying along over the small town w/ autogen at Dense and alot of other stuff maxed out to the right, and completely missing was the suble stutter issue. Thanks for the heads up on that, though as i say it wasn't gettin' me too bad before apparently. This is a very very subtle thing because the bigger microstutters are pretty much gone until frames drop, as w/ the NGX for example. Still quite enjoyable though.

I would not look for it Noel, it is a curse best left undiscovered. 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.

Amen.

I have an SSD and I have microstutters. It's vsync and nothing else... Although...

...the odd thing is that I last week I turned down ALL settings to the FAR left and ONLY had autogen at sparse... and I still had those stutters... I forgot to check the fps but it MUST have been more than 60. Usually I never ever reach 60 though...

Try locking at 60 w/ an ext limiter and see if you saw what I did. I think the little microstutter Glenn and Gary describe isn't an awful show stopper for me. I did a nice flight in the NGX from KSMF to KLAS, just dialed back autogen to NORMAL from dense, and some of the other texture settings a few notches to the right, and had a very nice flight and maintained always 22 or above, and the little microstutters were not noticed. That, however, is because I took off in the pre-dusk hours and by the time I got to Vegas it was pretty dark! Nuttin' like dim light to soften microstutters!

I should have said I also eliminated some of my stutters by other means before I tried this Ramdisk idea. Seeing that you have an SSD, yours are probably caused by something else, although RAM is still faster than a SSD. By my original post you may get the feeling it eliminates all stutters but if you read the thread I referred to and my posts in there you will see I also used a few other tweaks to minimize what I could before trying ramdisk. If you have similar hardware to mine I really think trying some stuff I did worth a try because I get 50 to 60 fps in normal flight, over 60 at cruise(this is what the counter says anyway) and the lowest is around 27 at a place like KORD. This is with dense autogen and very dense scenery. I did experience these microstutters and I can honestly say I rarely ever get one now(I have to do something very drastic to get one, and I do mean one,like executing a 2G turn in the Chicago area in heavy weather) .I do not have my AI traffic at 100% its at 75%. Even if the FPS gets low the images are still smooth. If you want to think that I don't know what I'm talking about I can understand that, since I am new here. I am just trying to help out. If you want more specifics I would be more than happy to share.

First of all: I never think someone new can't know what he or she is talking about. That wouldn't make much sense. Secondly, if you could share some more specifics (tweaks used) in a nutshell, that would be appreciated! I already tried every trick there is afaik, apart from that ramdisk one... I will check the topic you linked and see if it can help me, but if you could summarize it here... that would be cool.

Well the first thing I did is to read nicks tweaks and use some of that. Of course, I am assuming a clean install with sp1 and 2 applied. I do not use light bloom, or aircraft casts shadows on self, I use trilinear filtering. I use Vsync but its forced through my Nvidia control panel.Also make sure you keep your HDD defragged, I don't think this applies to an SSD though. I am going to say this because Bojotes tweaks really helped my weak computer but with this one it didn't seem to help at all. This is my opinion, but if you have a strong system a bunch of .cfg tweaks make things worse. I only use two. I set my poolsize at 450000000 using nicks guide as a baseline for a 1 GB Nvidia and a little experimenting. I use HT so I did set affinity mask to 254 and I did notice a difference(yes, I know there are many schools of thought on this but I swear it made a difference). Before I start FSX I also use Gamebooster to kill any background apps. I also found out these imageglobe files in Scenery\World\Scenery are killing my performance, these are used to render your very far distance scenery. I use a weather addon that limits my visibility to 50 miles so I can't see what they render anyway. So I simply disabled them by renaming them. In the FSX demo these files do not exist so this may be another reason why people complained they got better performance in the demo. To use Ramdisk you should have 6GB of RAM or more I have 6 but if you have more that's even better. Just google Ramdisk and you should find a few drivers out there. Most offer a freeware 4GB version, use this.(If you have less than 8GB ram the larger payware version isn't going to help you and I wouldn't want you to waste your money if this doesn't work for you.Keep in mind FSX and your OS will use 3GB while running so with 6GB RAM you only have 3GB to use for Ramdisk.)Next I downloaded a freeware called procmon. Its a process monitor that tells you what files are being read while a program is running(just fly around a little especially in a scenery dense area while procmon is running). I found out that FSX uses scenery/world/texture,scenery/global,sound,simobjects, textures, and a couple of others extensively. Unfortunately for me scenery/world/texture is over 4GB so I can't fit it on my Ramdisk(this is where a larger amount of RAM and the payware ramdisk could come in handy). So I took everything else I could fit into 3gb out of FSX and copied it into the disk. The next step is to link all those files so FSX knows where to find them.READ THIS http://www.howtogeek...ndows-or-linux/ this will tell you how and what programs to download(please use linkshell and not the cmd function unless you like tedious typing). Linkshell extension basically makes this a drag and drop operation. The key is to relieve your HDD of most of its work. That's about all. Every time you stop the Ramdisk driver or shutdown the computer you will have to copy the files you used back into the ramdisk, so I just leave those files I use sitting on my desktop. If you have ?'s about any other specifics please post, hope it helps, it really did for me. However you did say you have an SSD so I don't know how much speed difference there is between RAM and an SSD so this may not be your answer. But seeing that RAM is faster it still is worth a shot because I know people with SSD's that still use this. I guess getting anything you can into the RAM should help. Just really go over procmon and see what files your installation uses most. What I did learn about microstutters is there is rarely just one cause, they have multiple causes. This can make people think that something they tried isn't working but in reality it is because you may be seeing less of them. You have to keep eliminating the causes until you can get them all or get something you can live with.

I will try this but I don't know if this is really the cure against microstutters. I have very low latency memory and a SSD but still see microstutters in fullscreen. What I do know is that with my system windowed mode works best, as I found out yesterday. When I set FPS limited to 30 in fsx and fly in windowed mode I have absolutely no, zero, nada, niente microstutters. I'm almost with my noose on the monitor but have no microstutters whatsoever. I think this is due to the buffering in windowed mode. But on the otherhand, also with Vsync disabled I have supersmooth flights with my system. So please: Sandy Bridge owners (or similar setups) who experience microstutters: try windowed mode! This is how I test microstutters: Use a default boeing 737 on KSEA and use wingview so that you look at the terminal buildings when you take-off. When there are microstutters, you will see them when you pass the terminalbuildings with high speed. My system:SB 2600K @ 4.58 GB 1600mhz ddr3 ram (7-8-7-2T)120 OCZ Vertex 3 SSDNvidia gtx570.

I have a very similar system I have just setup in the last 2 weeks, with the major difference being an AMD 6870 and no SSD. 8GB Corsair and i7-2600k. I run Shader Mod 3, FPS enhancement pack v2 (This one works wonders on my system and past systems) and a tweaked CFG from *******' online generator on FSX Acceleration with REX graphics and ASE weather. I have absolutely smooth flight with all sliders right except traffic. I do not overclock anything on my system at all, as I don't believe it is good for components to be stretched like that, it'll only lead to issues down the line and possible overheating problems that you find out about when it's too late. So do you think that might be an issue, seeing as you overclocked from 3.4GHz to 4.5GHz?

Yes I am having similar stuttering on my new system as well. I have tried almost everything in the month that I've had it including upgrading my HDD but nothing seems to work. I don't think the issues we're having are the same as micro stutters either. When I look out the window I can see the ground shifting every few seconds. These are very noticable both with sliders low and slider max. I've gone back to my laptop. Much smoother And its too bad because I spent a lot of money

Can you tell us what PSU and Motherboard are you using , maybe that could shed some light on the performance and experienced members then could help you.

I'd like to share mine too. I'm using a GIGABYTE GA-P67A-D3-B3 LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboardand a RAIDMAX HYBRID 2 RX-730SS 730W ATX12V V2.2/ EPS12V SLI Ready PSU
