Hi! I bought a new computer this fall and have had mostly good performance with it. With the help of some of you guys here on the avsim forums and also following advice on simforums i bought a i7 950 (same price in my country as the i7 930 at that time) a Noctua NH-D14 heatsink/cpu cooler, an Asus P6TD Deluxe motherboard, mushkin redline 1600 Mhz DDR3 (6-8-6-24, 2gb x 3) and a EVGA gtx 480. Performance compared to my older Core 2 Duo e8500 with HD4870 was alot better, especially in stability and smoothness. A week ago i OC'ed my processor to 4ghz and after stresstesting and stability checking im quite confident it is a stable OC. I still have some minor problems though: Even though i've followed the settings for Nvidia Inspector that NickN on simforums posted my ping jumps up and down alot causing small stutters, especially in turns. It can go from 40 to 120 then down to 35 etc.Also texture loading when flying seems a little slow, and the autogen pops in and out, taking away some of the immersion of flying. With a 4ghz overclock on an i7 processor and my Gtx 480, shouldn't my computer be able to load ground textures/autogen a bit better? (Im using UTX/GEX). Right now im having about 40+ fps in the VC of the PMDG MD11 on ground at Flytampa's Vienna V2 in FSX. On some less optimized airports like Aerosofts Paris CDG/Norway Vaernes i get lower fps, more like 25-30 which is unfortunate but i guess theres nothing i can really do about that. After checking around for tweaks i found the bufferpool tweak, and first tried the usepools=0, which made it even worse, and caused a lot of instability, as you may see i don't really need more fps, i would happily trade a couple of fps for less stutters faster scenery loading. So i tried Bufferpools = 490MB and 200MB and 200MB seems to almost completely get rid of all the stutters, I still have the slower texture loading though. Do you guys know of any tweaks/settings for speeding up autogen/texture loading (im talking about blurry textures, but most of the time im flying at less than 200kts), would the reject threshold tweak help or cause more instability?Also my current FSX HDD is a 1TB 7200RPM WD harddrive, is this the culprit of my problems or can i solve this without having to buy a SSD?Any help is appreciated, thanks in advance :)

WilliamWe have similer setups and I believe we have the same outcome. MY FPS are all over the place with Tab's Nvidia inspector settings. I have a i7 950 thats stable O/C'ed at 4.0GHZ on the Asus P6TD Deluxe with 6GB 1600 DDR RAM..I highly suggest running your FSX.CFG thru Bojote's Treaking guide here http://www.venetubo.com/fsx.html If you want to have a optimized benchmark to work withFrom there to achieve better texture loading times/reduce blurries adjust LOD_RADIUS= I have mine set for 5.5 as I only have a 9800GTX+ but most use between 5.5 to 7. Default should be 4.5.Apperently the trick to elminiating stuttering visually and within the framerates is to limit the frame externally. Although I havent been able to find a frame rate limiter that works on Win7.

The one ******* links works - you just have to right click the resulting .bat file and choose "Open" when you want to run the sim, just double clicking it, doing Run as Admin etc don't work - it's a quirk of the UAC/permissions system in Win7.

I saw Saitek recommending this on their Twitter. It´s very neat.

Just right click on the .bat file and send a shortcut to your desktop (or create one and drag it to wherever you prefer). That way you can start up FSX with the FPS limiter by double-clicking on the new shortcut icon in the same way you would with the regular FSX icon. I have also modified my shortcut to use FSX's icon and changed its name to "Flight Simulator X". Works like a charm for me in Win7 64 (with UAC slider off).Dave

Hmm, the fps-limiter you guys are talking about, thats the one with a couple of .dll files, a .jar file and a .exe? If so i cant seem to get the exe file to start, nothing happens when i click on it, i've tried right click and open, double click, right click and open as admin. Everything.The file just flashes like its about to start but never does.

That's the one...You have to run the GUI to create a batch file first. That is run from the FPS_Limiter_GUI.jar file (Before you can run that file however, you must have Java installed on your system). Using the GUI you create a batch file that points to your installation of FSX and specifies your desired frame rate limit. Once that .bat file has been created, you use it to start FSX with the FPS limiter running.

Okay, i just tried the FPS-limiter now and the fps stays at 30 without any stutters. This was with the 747-400X so im pretty confident i will be able to keep that fps in most situations, although as i wrote earlier there are airports where i guess it will drop. AAbout the texture/autogen loading, would the LOD-range really affect that?EDIT: Right now im using BufferPools = 200MB, when doing the tweak-test on ******* website Usepools = 0 is used, last time i tried that, i didnt use an external fps-limiter and got big stutters and blurry textures, presumably because i saturated the GPU. I also hadn't overclocked my CPU. Im still a bit cautious about using a lot of tweaks however, could anyone tell me what the difference is between a larger bufferpool like 200MB, and 0, and the Reject threshold tweak?

I just gave it a shot with the frame rates limited externally (thanks ryan) and the difference was night and day. Stutters seem to almost be tottally gone. Im confident now that there isnt much more I can squeeze out of FSX on my setup, now wheres that damn NGX lol JK

Try this just this:[bufferpools]RejectThreshold=131072The default pool size should be fine. I hope you're not actually using 200MB, that seems excessively high - the FSX default is 4MB.

Most of those explanations are actually wrong. Read *******'s information, it's accurate. (we verified with former programmers on FSX earlier this year) For example they claim that the PoolSize is the amount of memory reserved for introducing textures. That's completely wrong, this is the size of each pool within the sim's dynamic vertex buffers which sit between the engine and the GPU - it has nothing to do with textures at all, it's the raw geometry the sim uses to build the scene.

Interesting, I must admit I never followed any of those guidelines, and never was able to produce positive results with manual tweaking details from this site. Rather I used guidlines that are deep in the archives of this very forum. So I appoligize if this caused any confusionAfter getting FSX to where I wanted it to be after spending hours here and there trying different cfg entries. I used Bojote's Tweaking service and instantly had way better performance then I have ever acheived on my own. From there I applied a overclock to 4.0GHZ, then re-ran my .cfg to reflect the higher processor speed.(FSX glory) I took a pretty big hit using Tabs Inspector settings, but after limiting the frames externally, FSX has never looked so good, and I now maintain 30ish FPS in almost all situations with minimal stuttering. Im picky about blurries so the only manual tweak ive applied is the LOD radius. I suspect you would have the same results and feelings after trying this. At some point your never going to get anything more out of FSX, and I believe the above will get you there.

What's your GPU? The video settings shouldn't have caused that much of a performance hit...

9800GTX+ 568MB. However I will gladly enjoy the huge decrease in jaggies and overall clarity vs the increased frames anyday, whatever that difference in frames really is anyways. Thanks for helping out myself and many others with the AA in FSX. If I get a chance before this thread dies down, I can benchmark the difference with my GPU, if it matters that much.

Hi there I have a similar setup with a newly i7 950 OV to 4.2 GHZ, 6gig DDR3 but a 9600 GT. I have tweaked the .cfg file as per this post and limited the FPS with the external limiter set to 20 and still get stutters. But I also have a HD 5770 videocard on another PC in the house and with that video card the sim with the MD-11 is flawless (virtual cockpit, AA on, sliders set to 90%, loaded in EGLL I get about 25 fps on the ground and nearly no stutters). Can't wait to buy a GTX 570 ;-)anthony brichart
