Haven't had any in a few years, and now for some reason they are back... and it's not just micro - it's mega stutters.. sometimes the entire VC pauses for about .5 sec...

 

Things that changed since they started:

 

1) Cleaned out PC and rearranged all the cabling/peripheral USB devices...

2) Mouse Properties->Motion-> I bumped it up one notch faster...

 

That's all.

 

I tried without Track IR

I tried with clear skies

I tried with default C172 (they occur but not nearly as frequently as payware like T Duke or JS41)

 

I've checked gpu and cpu temps - both are normal.

I've got nothing running in system tray that wasn't before.

 

One odd thing - I have noticed my Logitech G5 mouse seems to be less sensitive and "jumpy" on occassion, as far as the cursor tracking goes (which is why I set the mouse motion faster).

 

Anyway I'm attaching my Process Explorer list in two parts... maybe that will help someone identify something odd...

 

 

What kind of GPU? Are frequencies stable?

Ryan,

 

Have you run Windows Update lately? No new system updates? Do you run a firewall? Un-install it or any AV and see if it goes away.

 

I know you haven't done anything but that's no bar to a PC deciding to do stuff on its own!

 

I see also you are running Apple mobile device stuff..Is this new? It and bonjour can be problematic..Also, any Adobe resident updater and speed-openers..Also kill the JAVA update scheduler..You can update them all manually anyway..again, I know you may not have touched any of these but thy can all affect real-time application performance.

 

Also, I see you have USB3.0 on your board. See if disabling it in BIOS has an effect. My old board (P8P67PRO) had a bad USB3.0 driver that cocked up some stuff early on..You do say you've fiddled with USB...

 

I just built my new rig and had awful stutters after a day of mindless tweaking. It turned out to be a profile-specific power management setting. I know you know your way around your PC, but just see if it hasn't reverted to a balanced or power-saving profile. Windoze can be obtuse like this..

EDIT: Ryan, can you check to see if your mouse is plugged into a black, blue or red USB socket? One of the issues with my old USB was that it didn't aggregate the connections on the board. i.e I HAD to plug a USB3.0 device into the USB3.0 socket or it wouldn't work (they fixed the drivers and I could use any device in any socket). Weirdly, on my old ASUS board, the USB3.0 were blue, on my new one, they're red and blue..

Specs in sig.... EVGA GTX570 SC, stock freqs. Like I said, nothings changed as far as volts/freqs/temps...

No windows update lately...

No systems updates...

I don't run a firewall...

I run MSE

I am running Apple stuff for my iTouch

I run Divx stuff (which has an annoying updater that I can seem to get rid of- but it wasn't running either)

I run java with its updater (but it's not updating when I get the stutters unless there's some background app)

Yeah I've got Adobe Acrobat and Lightroom installed...

 

RE: The USB3.0 slots.... I've got two and they are blue on my board... TrackIR is plugged into one and that was the same as before.

 

I'll try to disable the software with updates... argh

Disable the memory-resident Acrobat stuff with MSconfig. It is crap. Earlier updaters had a memory leak and would jam up sometimes - make things slow down..I really don't like the PC-based Apple stuff, either..I know you need it, but I think Apple make the PC versions of their software rubbish for a reason

 

It sounds just like my issue which was the CPU having a quick nap as it thought it was too hard for FSX..

 

It would be really smooth, then jerk, jerk, then smooth, jerk, jerk..It didn't really matter what i was flying or flying over, and this was on a brand-new (like hours new) rig that about half an hour earlier was running like a dream. I went a bit funny...

 

Your vid card hasn't reverted to power management mode (as opposed maximum performance) in NVInspector or anything? Your power settings in control panel haven't reverted to a non-full power (i.e. unmanaged) setting?

 

If all else fails and you are pulling your hair out (as I was) don't rebuild your whole system like I did, :Cry: try deleting your FSX.cfg and doing whatever you do with yours and see if it isn't just a corrupt file..Other than that I don't really know. I hope you fix it. It drove me mad.

I have sigs disabled, and you'll have to monitor freqs. I had horrible stutters until I realized they occurred due to TDR problems. They appeared from nowhere, like CAT. I've mitigated the problem by downgrading to mid '11 drivers.

How about hardware. Could you have a cable that is slightly loose? Did you bump a memory stick? Are your cards well seated? Check your outside case connections too. All your fan connections good? You get the idea.

Nothing seems out of place...

 

As far as the updaters... I've killed off Reader, Divx (finally found the updater disable argh), flash player, and turned off my Canon printer stuff in the system tray.

 

One thing I forgot to mention was that I've been playing Battlefield 3, sometimes I'll play it for a few hours prior to playing FSX (and I don't reboot the PC)

 

With the stuff disabled, and NOT playing BF3 prior to FSX - it seems back to normal. It's possible the system or GPU was too stressed after playing BF3 for a few hours... I'm not really sure.

Ryan

Why so many Chrome.exe open I usually close all browsers except for 1 exe running.

Regards

pH

It was multiple tabs open... AFAIK...

Ryan

Chrome was occupying over 1GB in virtual size and may contribute to your microstutter??

pH

I don't know if this'll help, but when I get into such problems, I quit all my processes in the PE except the ones needed for windows and FSX operation. That is my first test.

If that works out, I start then excluding them with msconfig. Someone suggested that already...

 

You have to divide your testing into software and hardware side. Exclude completely that it's not software, then you can possibly start looking at the hardware (though I don't think it's hardware).

GPU was too stressed after playing BF3 for a few hours

 

I would think if that were the case your GPU temps would be abnormal? Sounds like a system hog scenerio.

Or a memory leak.... maybe it was Chrome... I don't recall what pages I had opened (nothing naughty)
