While I'm waiting for the revised Sandy Bridge motherboards my FSX on a C2D running at 3.0 ghz is driving me nuts. I've started to experience frequent intermittent 5-10 second pauses and can't figure out what is causing them. I thought I might be having odd processes popping up when the sim pauses, but I don't see any. I know that there are some programs that will close unnecessary processes when FSX starts, but I don't recall what they are. Any recommendations? Thanks.

Use AffinityMask=14 or 12 in fsx.cfg. If you bring up the proces list, right click on fsx and change priority to high. If you use TrackIR right click it as well, but change core from all four to core 1.Sure temperatures are ok?Bjorn

I got these after upgrading to a new version of Java. The default is toallow Java to prefetch stuff which it will do when you least want it to.In the Java control center, you turn this behavior off.Heaven only knows how many other programs decide from time to time to wakeup and do stuff. Are you sure you do not see something happening (using Procmon or similar)?That is how I found my Java activity..

Interesting... Just updated Java, and everything is just plain weird on my rig.When I open the Java Control panel the GPU crashes and eventually recovers after a short time, but what the heck is the matter with this moronic software?Where do I switch off this "prefetch stuff"?Actually, I can't even operate the Java CP - the GPU crashes within seconds, #####!The updates I've killed already....

Thanks kids. I shut down the Java updates and prefetch and also tried the AffinityMask tweak, I set AffinityMask=3for my dual core. I just competed a 20 minute flight with the Lotus L39. Smooth, no pauses or hesitation and the CPU workload pretty evenly balanced between both cores. I am a Happy Boy...Thanks.

Happy it worked for you! :(

For what do we need Java?

Hi , I got a question for crewecut. I tried your suggestion to change priority to high and change affinity mask in fsx. First in my FSX.cfg file I have Affinitymask =14 which should disable core o I think, but when I check it in task manager it always shows all four cores checked. Even if I try to uncheck core o next time I start FSX they are all check again. The same thing happens with setting it to high priority, it will go back to normal next time I run FSX. Do you have to set it to High each time you run FSX and not sure why all four cores are check if I have affinitymask =14 in cfg file. Also do you run other programs such as ASE only one one core? Thanks for any feed back.

I have an affinity mask of 13 set in the fsx.cfg. It means that FSX uses core c0, c2 and c3 out of my four cores and leaves core c1 for system related things. What do you have for a CPU? If it´s an intel with HT enabled, this isn´t the right setting.

The four cores are still available, but FSX will move most of it's heavy work onto Core1.If you look in Task Manager with FSX running, you will see that Core0 is not very busy.

Hi, no don´t use ASE. There´s a free-bee out there called Prio. Lets you set the cores for your programs, so you don´t have to do it all over again each time you run FSX. FSX will run threads through core #0 no matter what you do.Bjorn

My experience with stutters started right after new build computer. Used Nicks' guide, which is excellent by the way, but had stutters on views out the sides. Found a fix by Bejoe(*******) that changes a setting in the autogen.xml. BINGO-- stutters ALL GONE. This man has changed FSX totally for me.Clear skies everyone.

Flying, Do you mind posting that autogen tweak or where I can locate it. I have *******' tweaks but am still getting stutters on my new system. Thanks!

Yeah, posting this would be very nice, cause I´m suffering from the same shutters in outside view.
