What combination will make micro stutters gone

Recommended Posts

To all the HW Guru and FSX veterans out there, I have a holy grail question to ask: you have all seen this: a high FPS yet a slight stutter here and there that you will notice, and will remind you that your flight is not smooth. Will moving up to Sandy bridge and SSD finally conquers this annoying problem? I currently don't use SSD, my system is a i7-950 OC to 4GZ, FSX is tweaked to make use of more than 2 GB of RAM (using the tool suggested in PMDG MD-1 and win7 64bit. At medium size airport, with Autogen complexity 100%, Autogen 100%, 50% GA and Jet traffics, my Frame count is jumping from 10 to 60 FPS, averaging 30 FPS if I use an external rate limiter, the drop to 10 FPS is a fraction of a sec, but I guess that when I notice the micro stutter. I tuned my system using Nick's guide, using Carenado C152II, so not a complicate aircraft at all.Thoughts? What would it take to conquer these annoying micro stutters? High FPS really is irrelevant if the flight is not smooth.ThanksVu

Sometimes I get stutters, other times not. And it's random. I could be in the most CPU intensive payware with payware airport and it's not stuttering. (Mainly because the fps hover within the average +/- 10%). Other times I'll use default plane in a rural area and get huge variances. Like from 25 - 150 fps - then I get huge stutters. Locking in-game helps a little. But the best stutter curer for me was the v.02 FPS Limiter... just search FPS limiter youll find some good threads on it.

I have heard guys claim since the socket 775, that they had "smooth" flight. I have watched videos of a clocked SB @ 5.5GHz, and I could still see micro stutters. Honestly I do not think you can eliminate those real fine micro-stuters on anything.I can tell you that SB alone will not do it.

Anxuu00You said FSX is tweaked to make use of more than 2 GB of RAM (using the tool suggested in PMDG MD-1 and win7 64bit"FSX SP1 is already configured to use all of the 4GB of Virtual Address Space in a 64-bit OS (Physical RAM is not important as long as it is fast), so what tweak have you have applied? Could this be the issue.Certain tweaks to the fsx.cfg file may induce stutters and so have you tried, using a "clean" boot of windows then starting FSX with a "new" fsx.cfg file using the default flight and scenery to see if you still get stutters. (Without an external frame rate limiter)I guess that you have "pause on task switch" unticked?What is your video card?Is your PSU up to the job?RegardsPeterH :rolleyes:

Hi Peter and thanks all for replying.I did not know about the FSX SP1 fact, I used the "4gb_patch" utility from www.ntcore.com, and I do see a much smoother flight. I has FSX with Acceleration, so whatever that utility did it did its job. my PSU is a Corsair 1000W, Noctua NH-14 Cooler, and WD Raptor 300 GB, I use a GTX570. 24" 1920x1200 monitor, but I don't know anything about "pause on task switch", does that affect stutter?. Running FSXMark11 with the required setting my Min FPS is 15, Max is 49, Average 35, and as I watched the benchmark, I can notice the micro stutters, so it certainly not the raw FPS. I have seen good number came out with SB, but then as you can see with my FPS above, they are not bad either. So really, are all the micro stutters gone with the SB set ups I have seen posted here?If only we still have MS FSX team to answer why these micro stutters occurred and what to do to get rid of them! I can't go back to FS2004, I am hooked on ORBX scenery and FSX is just much better, but these micro stutters can drive me nuts sometimes.Really, for all of you pioneers out there with SB, is it really true that the micro stutters are gone? Anybody with SB system and ORBX scenery, and other add-on like GEX, UTX, REX? What your experiences? I mean raw number is impressive, but I am interested in real experience with FSX as you would use it with your favorite add-ons and SB.One can only hope ;)ThanksVu

You don't need to use the 4 GBy patch for SP2/Acceleration (but you still to configure Windows to allocate more than 2GBy to FSX).Cheers,- jahman.

I think I will try setting the FSX frame limit to 30 and noit using unlimited just to see if that will eliminate the micro stutters, heck I will also the external limiter just to see. I will let you guys know.Vu

Perhaps unwittingly :smile: , I think Gary hit the nail on the head here. A poorly configured FSX install will stutter no matter what hardware you have. In fact, an over-clocked Sandy Bridge could make stutters even worse vs a Core 2 Duo with similar stutter issues. My point: A socket 775 and Sandy Bridge can both run FSX "micro" stutter free. You just need to know where to look and what to look for.While I DO highly recommend Nick's set-up guide for Win7, I do have reservations about his FSX setup guide for users of highly over-clocked Sandy Bridges. My recommendation: Use *******'s setup utility for FSX. Oh, and most certainly, do search the Avsim forums for "micro" stutters as your solution is not likely to be found here in the hardware forum. Hint: ******* is a documented freak on the subject of 'stutters' ...

Do you mean the userva? that's not really necessary, his OS is a 64 bit one :biggrin:

Hi Ken, I just wanted to say that I have tuned to Nick's and *******'s tweaks on several hardware and software configurations over several years. My flights are what I would call smooth, but being discerning, I do detect micro-stutters. This under weather (ASE), PMDG-MD11, Cloud9, GEX, UTX, FEX and Genesis while coming into Toronto with Nick's scenery settings. Since I have experienced these stutters always under all mentioned configurations, I suspect something inherent to one of those products and or to FSX itself.Since hardware, software configurations vary, as does human sight and perception, I am always highly suspect when I hear/read these stutters do not exist on others systems if operated under identical circumstance (MD-11, 190kts, 3,000ft on approach to CYYZ, 3D view, look out the left window and watch the ground). . Maybe my eyeballs are vibrating; I am after all not getting any younger. :Nail Biting:

Ah, I see your point. And yes, with all those things running I'm probably not going to get water-in-motion smoothness with any hardware. My point: if one desires the truly spectacular sensation of water-in-motion smoothness then he/she is going to have to consider 'software' compromises -*******, helps us in this regard. ....I suppose higher end hardware gives us the extra headroom to maybe sneak in an extra goodie or two, but it's really about getting the software to gel with your hardware not the other way around.

I found it, well with my system anyway. I set the FSX rate to be limited to 30 and the stutters are gone. I guess setting unlimited and using an external frame limiter did more harms than good on my setup. I flipped back to the old setting just to check, and sure enough the stutters showed up. Even re-running FSXMark11 is much smoother now. Next year is my scheduled HW upgrade, so I will expect better performance. I believe the swing in FPS using unlimited is the culprit. When using FSX frame limit, the FPS hardly changes at all, which is why the I saw the sim runs much more smooth.Thanks all.Vu

The wrong bufferpools setting affects FSX. I have to set mine really low BP=3000 in order to achieve the smoothest sim and highest fps.I still have to lock the fps with the external limiter. I really need all the additional fps I can get and locking fps in fsx decreases fps from 5-10 fps.I'm not saying that one should focus on fps, the key "smoothness." This is the result of properly configured hardware, FSX tuning, and some tweaking.

What about update services running in the background?Antivirus, Java, Google, Adobe, Malwarebytes, Trojan remover, SpyBot, etc. etc.I found something over at forum.notebookreview - (I have a laptop Asus G73JH) - interesting read..."Tip for AMD GPU users for stutter/lag" http://forum.noteboo...tutter-lag.html

Interesting info DJJose. I was using Nick's guide to the T, and I was using the external limiter. I have good FPS but not smooth flight. I will try with a low BP setting to see. I guess you did not set BP to be 0? I suppose smoothness is subjective and depends on each person. I was going from Core 2 Duo to Core 2 Quad and then now on an i7-950. I upgrade HW every two years, but I wonder whether you will hit a diminishing return especially if one have high FPS but still have annoying stutters. Vu

Nick's guide dealt with removing unnecessary services, and I did not have any, reduced to the bare bone essential. Using FSX frame limit did the trick for me. I will try DJJose suggestion and report back.Vu

Hey guys-I wanna be clear on how I define stutters:Water-in-motion smooth -absolutely no stutters with NO joystick I/O lagSmooth -an occasional texture-load pause (HDD indicator lights up) with some I/O lag but otherwise NO stuttersMicro stutters -micro pauses despite solid FPS -textures already in ramStutters -looks like a photo slide show despite solid FPS -IE, solid 60 fps mixed in with an occasional fps dip into the teens.Chunky -single digit FPS with excessive joystick lag/latencyNow my FSX use:I only fly the PMDG MD11. I only fly into and out of the popular payware North American airports. I do use ENB light bloom, Rex, FSGenesis and WOAI -airline AI is 100% and all major carriers are loaded.So how would I describe my FSX performance ....Smooth I don't use a frame rate limiter or vsync. Instead I add or subtract FSX eye candy to control/balance system load <-----this is in the spirit of what Nick and ******* are try to accomplish. Is my system config bullet proof? The short answer is no. At cruise altitude I do have to confine myself to the cockpit or risk an FSX lock up, as my fps can sky rocket to as high as 200 fps using the external camera views ....switching camera views while doing 200 fps is asking for trouble, as some of you well know.Now, water-in-motion smooth is possible on my machine, as I said in a earlier post it is truly spectacular. However, I do like the ai traffic -lots of it, Rex and other goodies, so I did have to sacrafice the "water-in-motion" smooth for just plain "smooth". Again, one can achieve "smooth" on almost any machine, but a 5.0 GHz machine gives you more options to play with.

I believe it is all in balancing your system to your FSX complexityand the other way around... this involves trade-offs..Even on a non-extreme system, I can get Water-in-motion smooth flight..- fps limited in FSX at 30- no highway traffic- limited (30%) traffic settings for other and exit doors removed in AI aircraft- lod radius at 5.5 for better visuals- affinity mask = 12- 8XSQ AA and pre-render frames = 1 in nvidia inspector- FSX on dedicated SSD- GA aircraft (RealAir, Carenado, Flight1) with RXP gauges- Orbx PNW and RMN scenery with Victoria and Vancouver+Asus P5K, Q6600@3.2, Asus GTX 460 1GB, 4 GB Kingston RAM, WD Caviar HD, Kingston SSD

Good call on the exit doors, I'll try the tweak. I've been spending a lot of time tweaking AI aircraft and gate assignments over the past few days. This due to the signifcant changes in aircraft types and gate assignments at the real KSFO over past few weeks.Oh, I too use LOD (6.5), not so much for the visuals but to actually help with stablity....helps bring down FPS at cruise altitude.

How do we remove the exit doors in AI Aircraft?Remove the whole default AI bgl would help a lot, or??

In my case, I only use the default FSX AI airplanes andedited their aircraft.cfg files. No exit doors means nogate movement (and no calculations when you get into range of the next airport..)

Frame limit inside FSX is maybe the solution, a comment from "over there" Whistle.gifhttp://www.simforums...topic37713.htmlSorry about the spamming of Nick-stuff, some very ego-sensitive people here don´t like it...
No need to apologize for posting "Nick-stuff", PFL. However, I don't know who or why you would label anybody here as ego-sensitive. That title seems to go to NickN himself based on quotes like the one below that continue to pop up out of the woodwork. Yes, the quote is from the thread you linked. Sitting on his throne over at simforums and brainwashing his following into thinking that the AVSIM forum is a joke does nothing to advance the hobby. It's completely unprofessional! Whatever beef this guy has is from years ago... long before I and many others even joined AVSIM. I think he needs to pull whatever it is out of his ___ and go back to contributing advice without the spite. If he has some sound advice with an explanation that helps others to understand FSX better, great! But his simple observations are no more valuable than the next guy.Honestly, just don't blindly take anybody's word as the gospel. Try it for yourself and see what works. Sorry to derail your thread, Vu.
the tweak threads at AVSIM are a mile long with people returning for more/another tweak, or, 'change my settings' posts. I have yet to see it stop with a list of fully satisfied users. Some say they are and one, two or three weeks later they are back with another issue, or later they post to a developer (and waste real time and money) their aircraft does not work right,... to find out its some "god be blessed" automated online tweak tool, or, 'miracle shader hack' Its a never ending crock of crap is what it is...
