USBPORT.sys - LatencyMon says I have problems.

[evornoss]

Hi guys,

I've been reading a lot about this USBPORT.sys problem, but have tried everything and still no luck.

I have the power savings set to Performance, have Cool 'N Quiet disabled and Performance Boost (Turbo Core) disabled aswell in BIOS.

My main problem is that I don't get full performace out of this GPU under games, specially under Battlefield 3 (also other games, most of them). GPU Usage stays from 40% to 70% no matter what settings (low-medium-high-ultra) or whats going on in the game, therefore I get below FPS that what I should for this card/resolution. I get dips to 40FPS when with this card, in that game, should never hit below 60FPS. It lags sometimes, its unnaceptable for this card. My CPU doesn't hit 80% so this is not a bottleneck case (at least thats what I've come to believe so far.)

I've tried everything, I even Overclocked my CPU to 4.0GHz and no change at all (Back to 3.7GHz [stock]). Did a fresh install of Windows 7 Pro 64bits, no luck either. Right now I installed Windows 8.1 Pro 64 Bits, all updates up to date. still the same. I was getting this USBPORT.sys problem on Windows 7 too, still here on Windows 8.1.. so that got me thinking.. maybe its not a CPU/GPU Problem.. maybe its this USBPORT.sys problem?

Here are some screenshot of after about 40mins playing BF3



Any help will be DEEPLY appreciated. I don't know what else to do, seriously.

Help?

I don't know what might be wrong, but are you running any USB audio devices, like a headset for the games? Is there any driver update for it?

What type of audio setup do you have, onboard audio and any driver updates for it?

If it happens in Windows 7 and Windows 8, you may need to look at your basic system. Perhaps the bios needs updating, as the utility suggests, or memory or hard drive problems.

Anything in the Event Viewer?

Audio setup:

1x Creative SoundBlaster X-Fi Platinum, drivers up to date according to their website.
1x Logitech G930 Wireless Headset, drivers up to date according to Logitech's.

On board audio is disabled through BIOS.

I just changed (upgraded) my system. My system is now as follows:

CPU: Intel i7 4790K @ 4GHz
MOBO: ASRock Z97 Extreme6

rest of the hardware remains the same.

I am still getting problems according to LatencyMon (I think?), but this time around it tells me that everything is fine, although the last bar of the main screen is all the way up. I don't know if this is normal or not. This is what I got running LatencyMon for 39mins. Can you please tell me what to look for here in order to know if I am ok now or if I still have problems? I don't know which values are considered as normal or which are not, etc.

Any help will be greatly appreciated.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.


NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

The information you post would probably be very help for someone who had experience with that utility and what the numbers meant.

But I notice the Sound Card you are using is no longer available, so it may be older. I have not checked for its drivers, but you do have some from Creative that are for 8.1.

It is probably not relevant, but are you using a wireless mouse or keyboard...?

If I had a concern, as you do, I would test some things. First, disconnect the headset and connect a headset directly into the SoundBlaster. See if that helps, and if not, go back to the onboard audio to see if it might work better.

The headset appears to have some capabilities which might take extra time to implement, like voice morphing, so possibly it is just that or another feature causing the latency.

 

[evornoss]

Thanks for your input.

Yes, this Soundcard is kinda old now, but still I have the latest drivers for it. Still better than most of the integrated sound solutions in the latest premium MOBOs IMHO.

Indeed, my Headset has voice morphing.

Maybe as you said, someone who is more familiar with LatencyMon can shed some light on this.

Thanks again

Your new system looks normal; It could be better but its within normal spiking on latency. Also don't really put much thought in the pagefaults they don't mean much. On your original setup I would have laid the blame on the logitech usb headset.

Also many games suffer from what you describe as low fps and low gpu/cpu usage, which one are you referring to?

Hi there, how do you know this is between normal spiking? I would like to know that so I can learn.

I was refering to Battlefield 3, under multiplayer 64 players, NFS games, The Witcher 2, etc.. which all of them would drop very hard on FPS due to poor GPU usage. I got that resolved now, it was because of my graphics card (R9 280X 3GB) was causing a bottleneck to my previous AMD Phenom II X6 1100T, even when overclocked at 4.0GHz.

Hi, I'm going by your pic where even though it spikes to 500+ its still says its suitable for audio work. So I'm guessing its only spiking above 100 every few secs. But many things can affect latency; anything from your drivers, power saving features, enabled devices and even the motherboard itself can have an effect on latency.
Glad your issues are resolved and enjoy the sweet upgrade
