Hello people,Just wondering if anyone could shed some light on why the default fsx planes are now jolty after i have upgraded my CPU to E7500 2.9ghz. The CPU isnt compatible with my motherboard if that would make a difference. Im fixing this next week. Any suggestions would be grately appreciated,Cheers Shane

HelloI think you just answered your own questionOut of curiosity why would you expect good results from a CPU which is in an incompatible motherboard ?I am shocked it even works at all.

Yes i know it was stupid of me. But my compatible motherboard has arrived today so am gunna change it all over asap. Just wanted a second opinion that the incompatibility was what was causing the jolting as the add on planes such as PMDG 747 dont jolt. Cheers,Shane

I'm not even sure how that would work. CPU/MB compatibility usually involve different pin arrangements. Let hope you didn't mess up your new CPU.

Surprised it worked at all. Also you can consider your self lucky that you didn't blow the CPU. Incompatible can mean a lot of things - pin outs are different or VOLTAGES are different. If voltages, blowing a CPU is a good option.

Well ive upgraded the motherboard now and everything is compatible and CPU is still working fine. However my planes still jolt so no luck there. Im wondering whether it could be a bottleneck between graphics and CPU or memory and CPU?I have a nvidia Geforce 8600 graphics card and 2gb RAM at 667mhz.Shane

Shane, can you explain what you mean by "jolty"? If it's what I think you mean, I think I may have an answer, provided you have the rest of your machine set up reasonably well.Noel

Hi Shane,Try this if nothing else helps: Start FSX, then minimise it without loading an aircraft. Open task manager (CTR ALT DEL) then click on "processes". Find FSX.exe. Right click on it. Set priority to higher than normal. Quit the task manager. Load your aircraft. In 9 out of 10 cases this smooths things out.Kind Regards,Rob Young

Hello,Sorry about the delay,Robert: I set the priority to above normal and still no luck :(. Nothing has changed.Noel: By jolty i mean that every 5 - 10 seconds the default plane will in a way skip a bit. If that helps? Its hard to explain as it not a continuous lag.Shane

Ahh, then great, this *could* be an easy fix, unless you've already tried this: FPS Limiter.exeWhat this gem of a free utility does is limit frames TO THE DISPLAY, ie between the output of the GPU and your display, at least that's how it acts. When using FPSlimiter.exe, you will always set FSX's in-game frame lock to UNLIMITED. UNLIMITED optimizes some prioritization schemes in FSX, and delivers the best frame rate possible, however it also puts you at risk for periods of "slippage": when processing is easy, the sim will run very smooth, but hang and jolt during periods of high processing overhead. You will note this when you look out the side of the aircraft at clouds and so forth: smooth, hand n jolt, smooth, etc. You will set frame lock in FPSLimiter to 30 or so, which gives you the benefit of optimization, but restricts the overly fast processing during periods of low overhead. This differs from setting FSX's frame lock, since when that is done, you will lose the optimizations I mentioned. I have used this utility since I found it and it was the icing on the cake for me in a very big way. Do a search on this and you will find plenty of testimony that it works well, but usually only for higher end systems (ie, ones that are most capable of running the sim "too fast" if you will, thereby setting you up for too much variation between easy and difficult processing overhead.What does have me wondering now tho is the regularity you describe. If it's a regular hang, then one starts thinking about interfering processes from outside the sim, which is why I had mentioned provided you have the base platform set up well.

Noel,Thanks a lot, ill google that utility you mentioned and give it a try. Hopefully it shall work. A friend of mine said it is probably the memory not being fast enough or there not being enough of it. What do you think?By the base platform, i have just installed a fresh OS - Windows 7 - so there is practically nothing on the computer. My motherboard is not even a month old and the CPU is around 3 months old. Shane

Shane, I would doubt this is a memory issue. To the best of my knowledge, slower memory can translate into textures updating less quickly, so can make textures out farther stay lower resolution (blurrier), longer.

Noel,If its not a memory problem then could it be a bottleneck between CPU and Graphics card? I never had this problem before i changed the graphics card and now it is making my planes jolty. I mean its not the end of the world but its quite frustrating, especially as i cannot use the default planes.Shane

You 8600 sports a 488-bit memory interface. That's not bad at all for FSX. More is better, but that is good enough. I guess I should ask, what resolutation/AA/AF are you running?From what you describe it seems processing is smooth and fast, then will hang for a fraction of a second, then slip forward to the location the video would have been were it not delayed by whatever is slowing down processing. In the case of FPSLimiter.exe users who have shown good benefits from using this utility, it would seem the delays that are triggering the brief hangs are stemming from just plain old high processing demands accumulating on several fronts in the execution of FSX, versus interference from outside influences (outside of FSX, in other words competing processes for example).If you haven't, seriously, try running FSPLimiter.exe and see if that attenuates your jolty behavior. It is exactly what this application does!Also, are you using a BUFFERPOOLS setting in FSX.cfg? Example:[bufferPools]PoolSize=5000000 If you have any entry in FSX.cfg, delete it. So in the above example, you will delete both lines:[bufferPools]PoolSize=5000000At that point FSX will fall back to its default setting for BufferPools, and hide it so you won't see it. This has resolved some jerky video in certain situations. Alternatively, set it to 5000000 or even 10000000. I think you can get away with 10000000 with a card with 2GB video ram.

Noel,I cant find a download for FPSlimiter.exe i type it into google and its coming up with rapidshare and everything. But when i try that it says no more files. Have you got a link?Also what do you mean by AA resolution and all that?Finally i havent checked the Bufferpools because i dont really understand what i am doing with them. Do i delete them or change them? Also should i back the originals up? And where can i files the bufferpools config file?I really appreciate your help, and im probably coming across as a thick **** but i just really wanna get this sorted. I didnt have this problem before changing the CPU. I have also noticed that it dosent matter what plane i am in anymore add-on or default it jolts. It just seems to be worse on propeller aircraft such as PMDG J41 and default King airs. PMDG 747 and Wilco 737 arent as bad.Shane
