ScpService/server: high cpu usage even when idle

[JamEnergy]

Happens on 2 machines. Windows 10 or Windows 7.

It doesn't happen on my other Windows 7 machine though.

What are the common causes of this?

Would any logs be helpful?

I uninstalled and reinstalled a few times.

What is "high" CPU usage? What are the specs of the machine(s)?

[JamEnergy]

Hi there, I should have been more specific but here goes: The "good" machine is indeed quite powerful, like 4.2GHz. And I'm seeing SCPService consume under 1% CPU there.

The "bad" machine I'm on now is a Surface pro 3 (ok, I know they aren't power houses but it's an i7 that can boost up to like 3GHz). It seems to be eating up 25+% CPU (I'm guessing that's one core at max + a bit). Of course I expect this machine to exhibit higher CPU usage, but not so much more.

The other "bad" machine is like a 3GHz i5. Again, it was using one core at max.

What version of the software are you using? Are you using a Bluetooth adapter? Are any controllers connected? Does this also happen if you manually restart the service from the service console?

[JamEnergy]

Thanks for quick replies, and sorry for omitting such obvious information! Version of ScpServer and ScpService (I tried both). 1.6.126.15319

I'm wondering if I ticked the wrong boxes/too many boxes/something bad when installing it, but I don't exactly remember what options I picked. The functionality does indeed work though (ie, controller works fine... it's just that the scpService/server uses abnormally high CPU usage despite not doing anything)

Yes, I tried stop/start from Services.msc.

No bluetooth adapter. No controllers are currently connected.

The release you're using if over a month old. Please update and try again.

[JamEnergy]

Okay, thanks. I will do that, test, and get back to you.

Do I need to do anything special to upgrade? Or just stop services then run new installer and follow options?

[nefarius]

You don't have to stop the service by your own, the installer will take care of everything and prompt you for any additional actions needed. I recommend you to get the latest beta.

[JamEnergy]

1.6.206.15349 exhibits same behaviour. I can try the beta too.

[JamEnergy]

Same symptom in beta.

Could try ScpCleanWipe.exe (haven't yet).

Are there symbols in this build btw? Could VerySleepy it.

[nefarius]

You can select installing them in the setup under Testing & Troubleshooting / ScpToolkit Debug Symbols

[JamEnergy]

Doesn't mean a lot to me lol, but fwiw:

[nefarius]

You could do a Save as... and submit the .sleepy file so I can open and analyze it myself.

[JamEnergy]

Ok, sure thing.

For reference: SCPServer.exe build 1.6.212.15353

[nefarius]

Great, thanks. I'll have a look.

[nefarius]

Can I also have you log package please.

[JamEnergy]

Logs.zip Logs folder from C:\Program Files\Nefarius Software Solutions\ScpToolkit

Sorry for late reply, here's the log dir. If you meant something else, I can go and fetch that.

Thanks

To get the Log pack Search for ScpToolkit Debug Info Collector in your start menu, run it and follow its instructions.

[JamEnergy]

Oh, thanks for that tip. Here it is. ScpToolkit_Log-Package_jeremy_1450551150.zip

Question: There is a arrow next to SCPService in your Taskmanager click on it and look if it looks like this

I'm experiencing this problem too - 1 out of 4 cpu cores is at 100% utilization by ScpService. Attaching VerySleepy log of 10 seconds and log package, may help in differential analysis.

I'm using the latest stable, 1.6.229.15365. Windows 7 x64 fully updated. The abnormal CPU utilization is happening both with or without any controllers attached, either playing or without any inputs from the controller.

Same issue here NOTHING ATTACHED(Bluetooth stick not attached, Dualshock 4 not attached)

Windows 10 Pro x64, freshly installed(this includes Threshold 2 aka version 1511)

All I was doing was watching some anime in Media Player Classic Home Cinema x64

CPU is i5 4690 quad core @3.5Ghz(sayin 3.75 because of intel turbo)

[ArtStepanyuk]

Im having the same issue Windows 10 intel core i5 -4430 cpu 3.00GHz 25-30% load at idle state

[shoebaker]

Same issue windows 7 x64 intel at 25% idle. With controller connected or not, its always maxed one core out. PS3 controller with cable, no bluetooth. It all still works.

tried versions 1.6.229.15365 and 1.6.238.16010 same thing.

[Jan200101]

My last guess would be a Virtual Controller

[shoebaker]

Tried v1.5.5787.40106 and this problem does not occur. (previously tried v1.6.229.15365 and v1.6.238.16010)

[nefarius]

I now know what the problem is but not yet how to fix it. Stay tuned.

[JamEnergy]

Thanks for the update. Nice for us users to see that glimmer of hope.

Good luck.

I'm pretty curious as to what the issue is though. When you're done, could you sum it up? Were you able to reproduce it locally? If not, I can make a point to verify the fix for you.

[nefarius]

I think the libusbK.sys driver is to blame here (which I ditched in the upcoming release) so please check out the very next release to see if this fixes your issues.

[NPException]

I just wanted to let you know that I had the same problem. I now installed the latest Beta (this one), and the problem seems to be gone.

Thank you very much! :)

[danyboy666]

This fix is working perfectly. Processor usage dropped from 20% to 0.1%. Thanks.
