Hi,I recently upgraded my GPU and upgraded to an SSD. Fps is great, most of the time it's around 35-45 fps, sometimes it drops to 25, but that even happens on the best systems. But, there's one problem I'm having. Even though I have a tweaked FSX.cfg with bojotes tweaking tool, and I have an SSD, good graphics card, and I've set up Ryan's NVIDIA inspector guide, but still, I'm having some stutters. The stutters are only very small, but they happen a lot, all the time. It's not that bad, but it's noticeable. Here's, a video. I am using Fraps, which makes the stutters worse, but it's quite comparable. Fraps makes my FPS drop from 35 to around 25. I'm getting around 35 fps here in LFPG from Aerosoft normally. With some small but frequently happening stutters. Using an FPS limiter does not really work. If you have any suggestions, that would be highly appreciated. If you have a good system, similar to mine, with no stutters at all, I would really appreciate that!I'm just wondering, if everyone isn't seeing some occasional stutters? Even on the best systems? Perhaps it's just that I"m never satisfied or something...Thanks in advance,http://www.youtube.com/watch?v=LzOsuvQ7HsE&feature=youtu.be

I am running a somewhat slower system than what you have, and the only time I see stutters is when I am in heavy weather with lot of clouds , I run REX2 OD clouds.I am not familiar with Ryan's Guide for Inspector - I set mine up for Inspector using Nick N's settings for Nvidia Inspector for the most part, see here:http://www.simforums.com/forums/fsx-and-nhancer-settings-for-new-drivers-updated_topic36586.htmlI also do use the external FPS limiter, built into the latest Nvidia Inspector, set at 30 fps, and unlimited in FSX.You don't mention how your sliders are set - couple things that will really help with performance, lowering AI, turning off " aircraft casts shadows on the ground". Reducing road traffic helps as well. If you are running full autogen, might try reducing it a notch as well.Also, do you run the himem fix for your videocard? If not, you can try adding HIGHMEMFIX=1 under the graphics section of your fsx.cfg file.I suspect with a little tweaking you can get FSX really smooth on that system you have.Hope something helps, and good luck!

Thanks a lot for your reply. NickN's inspector guide is exactly the same as the one from Ryan, except for the Vertical Sync option, which he set to "Force on". I tried this, but it does not make a difference.Yes I have HIGHMEMFIX=1 under the [Graphics] section.I also have TEXTURE_MAX_LOAD=4096, which reduces stutters also just a little bit.Sliders:No light bloom or lence flare, advanced animations on. Aircraft: Ultra High, shadows off. Scenery: Maxed out except for Mesh comlexity which is on . No ground scenery shadows. Weather: Ultra High, draw distance 60 nm, coverage distance Maximum. Traffic: AI Traffic and airport vehicles off (because I only fly on IVAO). Road vehicles 50, boats off. Reducing the sliders (autogen) does not really make a difference.I also just found at that setting Maximum pre-rendered frames=8 in Inspector, reduces stutters also a little bit. But they are just still there. It's not as bad as in the video though (bad stutters because of fraps), the stutters are only very short, but happen a lot. I can live with it, but I would just prefer to have them gone. Just wondering, if it ins't normal that everyone (even with the best systems) is seeing some small stutters? Also my overclock is very stable. 12 hour Large FFT test in Prime95 with no errors.

It will be interesting to hear more feedback on this from others with systems closer to yours, but I personally think you should be able to run without those stutters unless under a really heavy load, like weather.As mentoned, I do get occasional stuttering but it really only happens to me when in heavy weather with my REX2 hd clouds, adn mainly if viewing from external view. Other than that, my flights are pretty much stutter free for the most part... and I run app 25% ai and road traffic.You mentioned you recently upgraded to a SSD drive, are you using it for FSX or just the OS, or both?

I'm using the SSD both for FSX and the OS. Is it recommend to have two seperate SSD's then? One for FSX and one for the OS?About the stutters, perhaps the problem is not FSX, but me. Perhaps it's just that I can never be satisfied. The problem is only very small, the stutters are very small, barely noticeable, but they are there...Just tried NVIDIA fps limiter instead of FPS limiter V.02, and I also found that this reduces it just a tiny bit.One and one thing: could the probelm perhaps be my monitor? My monitor only has 5 milli seconds of response time which not great it is full HD though...

I do not know enough about SSD's to comment intelligently on them, I know with mechanical drives the common thinking is to have FSX on at the least a seperate partition, at best on a seperate physical drive. I personally have FSX installed on a seperate dedicated 500 gb hard drive, just for FSX and 3rd party programs for it. I also have my page file on a seperate physical drive from the OS and FSX drives as well, as I have four hard drives I use.I don't think it is just you, I am very perceptive as well and any minor stuttering annoys the crap out of me.As far as your monitor, no I don't think that would have anything to do with it, 5ms is not bad and certainly good enough for FSX.One other thought - you said you recently got the SSD, is it updated to latest firmware and/or drivers for it? I know I have read where some earlier versions have caused issues for some SSD's. But again, my knowledge on SSD's is very limited.

I also just found at that setting Maximum pre-rendered frames=8 in Inspector, reduces stutters also a little bit.

I've always found preventing pre-rendered frames altogether, by setting 0 there, gives a much smoother effect, assuming the processor and video card are capable of real time rendition, which I think yours should be. I'm running a 2500K at 4.8GHz with a GTX 580 video card.You might then need to limit the frame rate to a value which allows the non-prerendered frames all to be drawn. At least they are then drawn at the correct time, rather than getting a possibly bunched up 8 frames, all prerenderd, then a stutter, which is what your demo video looks like to me. I liimit mine normally to 30 fps, but have tried 60 fps (in nVidia Inspector only) with success. But my system is a little faster than yours.RegardsPete

You might add this to your cfg, too, as the 560 (unlike the 580) is not such a hot card that it can get ahead of the 4.5-gig proc:[bufferPools]UsePools=1PoolSize=8388608RejectThreshold=524288 // 262144 // 131072//PoolSize=0Try it with an RT of 524288 first, and if it's smooth - drop it down to 262144, and then repeat for 131072.I don't think that you can run your setup with BufferPools=0

I tried this all, and eventually I found that RT=131072 gives me the least stuttering. BUT - it also reduces FPS a LOT. At Aerosoft EHAM I got from 35 fps to only 20-25! I really don't understand what the point is of using bufferpools, all it does is reducing fps, and barely reduces stuttering for me. PoolSize=0 still gives me the best performance... I just can't seem to solve this problem. Basically, FSX runs very smooth for around 5 seconds, and then a few stutters (it is comparable to microstutters), then runs smooth again, and after a few seconds some microstutters again. This tells me that perhaps there's a problem with texture loading, but I"m using an SSD!!! Even though I'm using the NVIDIA fps limiter, it barely makes a difference. I just don't know what the problem is anymore...Paul or Pete could you please send me your FSX.cfg? Then I'll try how that works for me.

I tried to put 0 in there, and it barely makes a difference. Do you have any other suggestions? It would be nice if you can send me your FSX.cfg! Thanks in advance...Are there perhaps any other settings in Inspector that could reduce stutters? I'm using NickN's settings.

I have a very similar system to yours - i7 2600k OC 4.5GHz, GTX580 1.5gb. I'm also running FSX and Windows 7 64 bit off an SSD. I don't think your problem is with FSX / graphics or cfg settings.....The only time I get stutters are for 3 x reasons -1. If I set the FSX frame rates to unlimited - I get big jumps in my fps sometimes 25fps to 150+ fps. It's definitely these massive variations in fps that cause some of the stutters. The only way to fix this is to limit my framerate within FSX to around 30-40fps (depends on which add-ons i'm running) Obviously when you use FSX's internal framerate limiter - you loose some performance (FSX eats around 5fps when you limit) This is why it's best to use an external framerate limiter. N-vidia Inspector now has this function built in and I've heard it works well (i'm still waiting to try it - Wife permitting!)2. The other thing I have to do is switch my anti-virus program to 'Silent Mode' - This sometimes causes some latency issues within FSX when it suddenly decides to do it's own thing.........3. Last of all - I disconnect from the internet. My system always seems to be trying to do something when i'm connected and this also causes my micro stutters.One last question - Are you using Track IR?? When I have my micro stutters - I notice the LED Light on the left side if the IR receiver flickers on and off when the stutters are happening. Disconnecting from the Internet cures this every time.Hope that helps a bit?Dan Pye

@arjenfsx:1. Aerosoft EHAM is probably one of the worst performing of AS products, so you will def. get stutters there...2. Check your system for programs running and updating in the background, antivirus, Adobe, Java etc.

I'm using Microsoft Security Essentials. I even tried deleting it but no difference. I tried disconnecting from the internet and no difference. This would not be an option anyway as I only fly on IVAO, and how am I supposed to get real world weather without internet? Lol. And no, I'm not using Track IR5. What I just found which helped a little is this. In my FSX.cfg I changed these Bufferpools settings:[bUFFERPOOLS]UsePools=1PoolSize=3000RejectThreshold=131072In combination with the Inspector fps limiter to 40 fps, this did reduce the stutters to an acceptable level, but they are just still there. Btw, what you saw in the video is way worse than what I actually have. Fraps is causing a lot more stutters than I normally experience. I would still really appreciate that I could get your FSX.cfg! Please PM me and I will send you my email address.

I tried deleting MSE and no difference. I do have Adobe Reader X and Java software installed, but how do I know if it's running?

Fwiw - thought I would experiment with bufferpools as I have never done so, I added the poolsize=0 to the fsx.cfg, and it made quite a difference for me performance wise, especially on the ground at the airports. FPS certainly went up, and it was very smooth.I am running an EVGA GTX 460 1gb video card...

A BufferPool is a chunk of memory reserved for fresh data pages, indexes and graphic information are placed so that the cpu can manipulate that data, such that it can be sent to the gpu and then placed on the monitor. That processing can now be done by the gpu, thus there is a lesser need for that memory space. If the ifo comes to fast for the gpu to manage it - you will get a stutter - and so you should use a buffer to slow it down. If your gpu can handle more than the proc can push - then you don't need a buffer poll at all. Only by estimating the need, and then playing with the poolsize and RT can you arrive at a workable solution. The 580 works very well with a 4.8 gig proc, however - in IFR conditions, with "VFR" scenery and traffic all high - I need a buffer, so I use a cfg where the BP is "1", and the RT is 262144. Frames are limited to 30 by Inspector, with unlimited set in the cfg. This does not imply that wrong BP settings are the cause of your stuttering, as there are many other causes that will create them. At one point I turned off EZCA - stopped using it because there was a 'jump' every 4 seconds or so - and it fixed it!. Stuttering can well be caused by anything which 'checks in' with the internet, such as a 'DropBox', Steam client, A/V client, any 'Update', and for sure - there are settings within the Nvidia client, (or Inspector} which will also cause these kinds of issues. There is most often NO specific cause, but rather a whole range of settings which are moderately innocent on their own, but when added in with six or seven other 'parties' will cause these symptoms. In any computer or server setup there is a 'Best Practice' that should be followed - some of these BP's are - never install a "Yahoo" search bar: don't use Win7's Aero: keep HT off: turn off indexing; turn off the search engine; get rid of 'Themes' (use Windows 'Classic'); turn power scheduling off; turn screen savers off; no shadowing under Icons; don't hide known file extensions; defrag the drives; use 1024 x 1024 clouds; keep the OS and FSX on separate drives; ensure the swap space is large and contiguous; use Ken Salter's AlacrityPC to kill all extraneous services and un-needed services; turn off the anti-virus and anti-malware systems when running FSX, (but always keep the firewall up): don't ever, ever download from a torrent site; backup each drive backup the system, use an image method if possible: I cannot speak too highly of Acronis and it's daily incremental backup.In short - became as near as possible to being an expert on your pc. Know it, and its' Operating Sytem inside-out. Only by doing this will you become the boss-man. Any machine with a 5xx-series card, and an i5/i7 can be made to run FSX smoothly, and with pretty decent graphics. It just take patience!

Hi Arjen;Your BP settings are quite wrong. Your poolsize has to be considerably larger than the reject threshold, otherwise everything over 3k gets rejected!Bring the pfs limit down to 20 or 25 not 40 - the pc will do 40 or more over the default desert, but not over Orbx PNW or KBOS or KSFO - type scenery. Believe me - a very smooth 23 is quite achievable with the right settings almost anywhere in FSX with 95% aircraft and payware sceneries.Yes - Adobe calls home, and Adobe runs in the background. It is one of the first "must shut downs". You can stop MSE and Adobe with AlacrityPC, and I can send you the settings, should you choose to download the app. It's free. Incidentaly - MSE is one of the best and least intrusive security solutions, but you must also disable Windows Defender, as MSE replaces it.
