very frequent stuttering, repeated logging of controllers in log file

[Von Thrud]

Hi team,

 

getting a lot of stuttering in various a/c, smooth in between stutters, good fps, no difference with res / or graphics settings detuned etc.

 

usb power management is mostly turned off that I can see and power management is at ecological unsound levels.

 

I have noted in my log file I get many repolls of usb controllers and they all get assigned a new id number each time... (TM MFD's, Warthog J and T, Groovey Game gears x 2, mouse keyboard)

 

hope this helps the bug squishers..

 

regards

Update. 20161110...

 

Stuttering fixed generally, except when I get track IR disconnect / reconnect msg - which is only when my track clip pro is off my head - seems to work much better

 

I have uninstalled / deactivated everything, deleted all profiles / saves directories and done a fresh install.

 

Win10 64bit patched.

Z77 mobo I7 K

 

16GB 2133 ram

980Ti.

 

DCS on second SSD

OS on first SSD

temp folders and save game file on separate 7200rpm HDD on separate SATA controller.

 

USB devices on mixture of internal and expansion card ports, plus Phillips 4k monitor usb hub builtin.

TM MFDS

TM warthog J+T

2x groovey game gear gpwiz 40's

M&K

Logitech headset

 

All USB power management options disabled / off in various device pages.

 

DCS added to AVAST antivirus

 

Nothing really fixed the frequent micro stutters until I reinstalled.

 

Also I have not reinstalled all modules... just A10c, F5e, Mirage, OPF campaign (previously I had everything installed except 109 and 190 and C101)

 

What I get now though is still the massive stutters on trackIR unplugged etc msg.

 

Log attached.

 

cheers

deattach ALL usb devices and take a round with keyboard only, if it is then stutterfree you have a faulty USB implementation ( Asus mobo ??,, DPC latency bug ?? ). Could very well be

Windows 10 Ann Ed. Integrated new Selective Suspend/Sleep settings for USB.

 

Google it, there's guides on how to fully disable it,

 

This problem affects more than DCS World.

@bitmaster, Good Idea, my original exclusion based troubleshooting idea was to buy rift.... I can't exclude a faulty USB device through I have swapped the ports they are connected to and disabled USB 3 in bios... cheers

 

@skatezilla, thanks for the tip, I guess it's registry editing for me as I have done the power management and device manager usb power management items to the ports / hubs etc ... cheers ... though I can play arma 3 helicoptering with TrackIR and HOG controls just fine, albeit I don't use the mfd's and Gpwiz boards in it.

 

I'll need to be a bit more systematic with excluding devices to narrow it down...trying to avoid a complete win reinstall....

@skatezilla.... I have googled and found all the win 10 gui based options in power management and device manager to turn off USB related power management settings and selective suspend. I I still get the TRackIr unplugged error and stutter at this time.

 

I downloaded a program which delates all old USB device entries.

 

My searching for registry tweak has proved unsuccessful for windows 10 specifically.

 

I have gone from dual screen to single screen - full screen option and removed the USB gpwiz 40 device which had the majority of physical switches (for my AHCP panel) from the setup which gave me the most problems with USB resets causing CICU to reset in flight (sad panda)

 

Do you have any other advice of searches or registry tweaks that I have not tried?

 

Thanks for any help

For me the fix was actually disabling the onboard audio.

 

I only narrowed it down when I reinstalled windows and the original sound drivers.

 

Intermittently realtek would say device plugged in, then device unplugged which would also trigger off dcs to reinitialise the USB devices.

 

Once I disabled the soundcard in the bios all was good.

 

I did originally pull the header cables to the front audio panel but realtek still thought stuff was being plugged in...

Thanks for the tip.. will try as i have usb attachment on my logitech g530 headset as primary audio anyway and can go without it.

 

Did you get trackir unplugged the plugged in messages and massive stuttering along with any usb controller based panel with single or double throw switches cycling as the usb device connected again?

 

Ps. Great job with SRS.

Yes got plugged and unplugged messages for trackir, massive stutter and switches reset.

 

Hope it solves it for you

Sadly it doesn't work, might have hardware issues... the only way I can test is to expedite building of new rig with new mobo.

 

With my groovey games gears unplugged as well as TM MFD's... happens in 203 and 155...

 

thanks for the help anyways

Specific Intel Mainboards had a Device in the Device manager you had to disable to fix the random powering off of USB Devices

[WindyTX]

I am getting exactly the same problem but only since the latest update and it is affecting seceral of us witb random dropping of fuel tanks and Missiles etc.

@ ciribob

 

This seems Like a nice Southbridge issue. Sound--USB--SATA--etc---..they all derive their PCI-Express lanes from the SouthChip and if you have too many devices struggling to get on da bus

you still have problems with bandwidth and channels not available when you need them, as in the days of ISA cards and Jumpers...

 

I would DISABLE --ANY-- of the devices on UEFI that you can skip...IEEE1394 for example, COM ports, 2nd NIC, WLAN ( if not needed )...etc... this will free up resources and may get the left lane free for devices to shuffle their data without hard interrupts.

 

I'd try that and see if it works.

 

Also, additional cards in PCIe slots can cause this. Standard i-CPU's have 16 Lanes in the CPU tp drive the PCIe-16x slots ( and those only ! ). If you happen to have an additional card in any of the other 2 or 3 PCIe slots that may or may not lead to Express lane issues.

 

Usually, when you plug in any other card in any of the PCIe16x you downgrade the others. Sometimes with unwanted side effects.

 

 

Unplug it all, take a minimum approach and see when you get the problem on board when you enable one after the other.

 

Happy troubleshooting

[Ciribob]

Thanks!

 

Tried but still happens so I guess it's a driver and/or hardware issue.

 

No worries though, no issues with it disabled and using my USB headset

Maybe fixed - at least significantly improved

 

I followed these instructions...

 

 

http://www.aef-hq.com.au/aef4/showthread.php?44812-Found-a-fix-for-juddering-stuttering-in-dcs

 

 

Then I also went into regedit and drilled down to the following branch

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB

 

in there I searched for "enhanced", this would give me every USB device with a key of

 

"DeviceSelectiveSuspended" or "EnhancedPowerManagementEnabled"

 

and I set the value of all those keys to "0" from where it was "1"

 

Additionally, I have been through device manager and into powermanagement tab of any usb device that had, I turned off power management.

 

Lastly, I disabled usb selective suspend in power plan settings.

 

 

The performance in 2.0 is vastly better in terms of stuttering (however 2.0 > 1.5 on my pc in general performance terms anyway).

 

I still seem to get the TRackIR disconnect msg periodically with the device off my head, however the massive stuttering at other times has gone.

 

Am too far into changes to know in isolation which items were the "effective" fixes and not enough time to analyse it further. Just happy performance is better.

 

I still get some USB based switch / button panel cycling however though so that's still annoying however, the massive stuttering is gone in both versions, more smaller stuttering in 1.5 but playable again (even prior to today 2.0 update)

 

cheers, hope this helps someone
