I changed it to system managed, however it when I open it again, it back to custom. It will not stay at system managed.Bill

After ticking System Managed, did you click on SET?Alex

Been a long time!- it was a tip I saw here in the forums. I think I set it to System Manage as a performance optimization- about 3 years ago?Alex

Nope...now I did..going to reboot and let see what happens.Thanks AlexBill

Ok, the stutters are still there..Im going to play around a little more with the config and see what happens. Will let you know.Thanks,Bill

No luck...I did notice a very slight improvement manual putting my inital size memory to 3070.Bill

Did you update your sound drivers or your MB drivers? yes or no?Sound- reduce the sound acceleration in dxdiag and try it.Dont "doubt" anything. Try the newer vid drivers.Earlier poster stating the "sweet spot for YOUR system" is spot on.There is NO magic bullet !!!

Mobo and sound drivers are up to date. I guess I can try the 8.1 series drivers.Bill

forgive me for asking but "up to date" drivers from the CD or drivers from the manufactures website?and can you try reducing the sound acceleration just for testing purposes?Do you have on board sound or sound card? and have you removed your cfg(remove it from folder and backed it up some place) and then let fs re-issue a new one? that will eliminate the cfg and you can leave it alone.What about your actual vid card settings? Are they set for High Performance or Best visual? There is a myriad of settings there.Saw you updated fsuipc but have you removed it from the modules folder then tried fs?Its going to be something simple and you'll run across it be changing things and trying different things. These issues defy logical deduction sometimes.Keep at it.

Thanks for the reply, I updated the mobo drivers from the ASRock website, and updated my sound blaster audigy 2 value card driver from the Creative website. I will delete the fsuipc file from the modules folder and see what happens. The settings on my video card are:AA: 4XAF: 16 XTexture Preference: high qualityMipmap Detail Level: high qualitywait for vertical sync: application prefRefresh Rate Override: same as desktopThanks for helping me sort this out.Regards,BillP.S. I will lower the sound acceleration 1 notch

Ok, taking the sound acceleration 1 notch did not do anything, then I removed fsuipc.dll from my modules dir and that did not do anything. Then I took my videocard settings and lowered all of them to:AA: 2XAF: 8X with performance modeTexture Preference: performance modeMipmap Detail Level: performance modewait for vertical sync: application prefRefresh Rate Override: same as desktopThe results are the same, even though my sim looks like crap with the settings, the micro stutters are still there.There has got to be something that Im not seeing.Dont give up on me guys, help me through this.Thanks,Bill

I head its recomended to have V sync set to appplication pref for FS9. If I turn it off, I get tearing in the sim.Thanks,Bill

I've always turned V-synch OFF since early days of computing with no bad results, at least try it.Did you move the fs9.cfg out of the folder and let FS generate a new one?Believe it or not you're actually getting somewhere. You've been eliminating things.Now, you havn't eliminated the programs that could be running in the background. You'll have to find that thread or the programs that look at whats going on in XP.search here for stutters and look for it.Stay with it.

Doesn't work, tried it and mouse became virtually unusable. Also screen draw when FS windowed was painful to watch :( Definite no no here.Mike

Ok Bill,I might have missed some post in this thread and I'm sorry if I repeate an advice. But here I go: Have you checked your PCI latencey setting in BIOS? If this is set to a high value, such as 128 or higher, this might cause stutters. If so, set it to 64 or 32 and check if this eliminates stutters. I've seen that you OC:ed your CPU, so I guess youv'e got the BIOS settings under control ;-)Hope you get rid of the stutters!Ulf B
