Hello guys, I have an i7 2600K overclocked and I have problems with the smoothness in FSX.I receive in every situations 30 FPS with addon sceneries and payware aircrafts ( par example the NGX from PMDG ), butit is laggy and not smooth enough. I used the external fps limiter set to 30, I have 30 fps but in a kind of tearing way. It really sucks. I have done so many tweaks, but I can't get it smoother. I set vsync to 1 (on) in my fsx. cfg file. What else can I do to fix it. Any constructive solutions? Look at his vid, that is smooth with 30 FPS! But I receive hickups a lot of tearing and it is not smooth like in his videos. mine at 30 fps is a dia show experience. :-( Have a look at it: http://youtu.be/e_MqRV2gHnk My pc specs: I7 2600K, overclocked to 5 GHZ16GB Ram CL9 1600MHZColorful GTX 580 1536 MB1 HDD Samsung 7200 rpm Thanks to all. Kind regards, Tommy

Which settings do I have to do in my Nvidia control settings to get FSX in a smooth way with 30 FPS?AA and Anisotropic is checked in FSX, nothing else.Thanks for help and any suggestions, that might help.

This is probaly a 1000th post about stuttering. There are always same suggestions.Constructively can't tell you much, since it all depends on your configuration. Stutters can be FSX-internal or come from the System too. It's hard to impossible to detect from outside why you have stutters.My FSX is running same smoothness, especially if I'm flying that slow.I'd suggest you start by looking at your system, see if there are processes running that occupy the CPU or HDD, analyze one by one, I always say: you gotta know your computer otherwise you are lost.2nd, remove all the tweaks. FSX must run smooth without any tweak. Then take suggestions on NI profile from Ryan and PMDG's forum. Tweaks are only there to make it better but not FIX things.In the end, smoothness is one personal's opinion. What is smooth for one, isn't for other.Have fun.

Search for 'nick needham FSX tweaks' on google. Follow Nicks guide helps alot for me

Suggest searching for stutters onthe forums and having a read to get a feel for why this can be an isue. On a more practical level: 1. Turn off hyperthreading and use affinity mask 14. This makes fsx use cores 1, 2 and 3 leaving core 0 to deal with the operating system and backfround processes (as these are the cause of most stutters). 2. Use the bufferpools-0 setting as this moves some of the memory load to the graphics card DRAM which is much faster. 3. Try running with your antivirus switched off (these can sometimes be a cause of stuttering). These tweaks do not always work so well on a weak system, tbut they will be perfect for yours Tom, Cheers, IAN

Thanks for your nice post and your hints! Kind regards, Tom

As Ian has suggested, good points, however, with the greatest respect to him I suggest the bufferpools tweak comes last. Any tweaks should be introduced slowly and only once FSX has been maximised efficiently in other areas. Try simply running your frames locked at 30 and do away with the limiter. Apologies if I'm making too much of an assumption, but you didn't say what autogen you are running at. Set it at normal, especially with the NGX. I know you have a lion of a rig and it should run things fantastically well, but it just may be that you are still expecting too much from the autogen settings. Two small adjustments but in my experience they can have a massive effect on smoothness.

Oh btw. a thing about the external limiter... it slows down texture loading. Maybe you don't see it, but it's there. Also limits CPU usage and introduces stutters. In my humble opinion, internally locked is way better.

I wouln't disagree with you Rockliffe, but he has a pretty good video card with 1.5 GHz memory, so I thought it a worthwhile suggestion. I didn't personally see any benefit using the external limiter Word Not Allowed, so I ditched it. Some swear by it though. For me an internal frameratel lock between 40 and 45 works best, but this setting is always very system and setup dependant Cheers, IAN

There are only TWO fsx.cfg tweaks you need. For me, these are mandatory tweaks. Are you ready? [bufferPools]Poolsize=30000 Your card can handle BP=0. AND under the [GRAPHICS] section.HIGHMEMFIX=1 Start with a clean cfg. Then try the above tweaks. LOCK FSX at 30fps. Enjoy! Hope that helps.Jose

I´ve made the experience that disabeling the page file and using all the RAM (and you have more than enough with 16 GB) for it, gave me a lot less shutters. Just my 2 cents.

Oh yeah, it gives you shutters!

With my former setup it was exactly as you describe.With my current setup it runs way smoother with the external framerate limiter set to 25 and to UInlimited in FSX. I have to say I only test stutters/smoothness when flying over Nl2000v4 being near As Schiphol.That is the most difficult place for my system and if it is running smooth there than it will everywhere.

+1 . Schiphol is one of my testing spots as well. Jim
