USB Slots cause input lag

[icancanakci]

Hey. I've recently bought an Alienware 17 R4 with 120hz QHD screen. I'm happy with the performance but there are some weird things that happen. First of all, after a few hours, I notice a little performance loss. It only happens in certain games: Overwatch and Black Ops 3 and a few indie titles. There is no throttling, the max heat my gpu gets is 65c and cpu gets max 60c. There is something else %100, when I restart the pc it goes away for another 2-3 hours. My real problem is that my USB slots seem to cause MOUSE DELAY or INPUT LAG, which is annoying in Overwatch for exemple. when I move the USB connection a little bit, it changes the delay. There is a sweetspot, if I move it even a little bit I get lag in my mouse. This applies for both of the USB slots.

I have v sync off
My mouse's polling rate is fine
Resolution is native
Drivers are up to date

This is the safe mode test. I realised that it says "your system is ok" but havent changed anything since the last test which said "there is an error..."

Good old ndis is haunting even at safe mode. Your ethernet and bluetooth drivers are disabled btw. Im not sure if corrupted ethernet driver can cause this issue if your not even using it. Did you run malware and rootkit
scans in safe mode?

 

[icancanakci]

Yes they are ran in safe mode. I disabled them after a suggestion of another guy in another forum, didn't help anyways... It is not different when they are on

 

[fagetti]

Are you using bluetooth at all, you can try delething those bluetooth drivers completely. Dont worry you can install them agan later if needed from your laptop manufactor site. I cant find any windows 8 driver for e2500 that could be the issue there is only one for windows 8.1, latencymon says you have windows 8 or is it 8.1?

 

[icancanakci]

I'm actually using windows 10. By the way here is the thing. The test above that I thought was ran in safe mode is not actually ran in safe mode. Now when I tried to run latencymon in safe mode it gave a driver error, something like "the driver is disabled". So I can't run a test in safe mode. By the way I very rarely use bluetooth so I will delete that if I'm sure that is a problem.

 

[icancanakci]

About the 2 dell drivers you told me to remove, I disabled the Dell Diag Control Device (it is gone after uninstalling everything dell related anyways) but the other one does not exist. There is only these stuff: https://pasteboard.co/HavPQqI.png

 

[fagetti]

We already got rid of one latency issue :


Highest DPC routine execution time (µs): 1840.586895
Driver with highest DPC routine execution time: DDDriver64Dcsa.sys - DDDriver.sys, Dell Inc.

These dell programs caused huge latency

Highest DPC routine execution time (µs): 799.816239
Driver with highest DPC routine execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation

this one is still problem, ndis.sys

This leaves trying to reinstall older drivers for wifi and e2500 ethernet. Go to dell site with your laptop model number and search exact drivers. Check from device manager 2nd click and properties what is driver version. Then go to dell site and download different or earlier versions of wifi and e2500 ethernet. Put those files to desktop since when you delete wifi you cannot connect internet before installing new driver. first delete and install e2500 ethernet and do another benchmark and browsing test with latencymon. Post results here, if that wont work then we need to delete wifi

 

[icancanakci]

I'm actually quite nervous about this cuz I literally can't live without wifi Updating the driver right now.

One minute test with the driver uninstalled:

Well here's the thing, I uninstalled the NVidia Sound drivers COMPLETELY and Overwatch seems just a little bit better right now. I need to make more tests tho.

Bingo


Highest measured interrupt to process latency (µs): 210.415916
Average measured interrupt to process latency (µs): 4.374242

 

[icancanakci]

so you are saying it is solved? 😀

 

[fagetti]

Your DPC latency dropped alot after removing e2500 driver and after installing it back was raised again. Problem could be already gone as it states system is ok to handle after removing DELL programs.
Try to keep latencymon on the backround when you play and look how higb routine DPC goes

 

[fagetti]

I think you had multiple latency issues. Too bad we went too fast and deleted everything so now its hard to say what affected most 😀 . Atleast huge spikes went down after deleting all dell related so thats my best bet.

 

[icancanakci]

Update, after a day of testing I can say that nope, the lag is still here. It's not as bad as before but still feelable and annoying. Especially when I move the USB cable of the mouse the input lag increases or decreases. Disabling wireless completely does not solve the issue as well. There is a USB C port in my computer, should I buy an adapter and try it on the USB C port? Thanks.

 

[fagetti]

Oh god, this will get more complicated now. I dont think USB C will solve the problem because both USB A ports are on the motherboard so issue is somewhere else. Did you check every port on your laptop for bent pins? Look picture:

Also make bootable memtest, search it from google and change booting order in bios to your bootable dvd or usb. Run it and see if it passes few times without error.

Make bootable operating system DVD like linux ubuntu. It runs completely from dvd so you can test it. See if lag appears there and use latencytop for testing latencies.

If you remember that laptop didnt have input lag and it started suddenly you can try using restore point from windows to see if it will fix it.



Update your bios to newer version if you have outdated version (this is your own risk, check warranty)

 

[fagetti]

IT might be cpu related i had this when overclocking with a bad psu. Go to bios from boot and disable speedstepping. Save with F10. Do you have any overclocking settings or everything stock?

 

[icancanakci]

I think everything is stock but I can't check through bios cuz it's a very simplified kinda bios and I can't change much, including speedstepping.

 

[icancanakci]

I found and disabled speedstep, when I saved and restarted, I opened up Overwatch, and even before that I could see that my system was slower. In overwatch, I normally get around 230 fps, but this time I got like 40-50. Also the sound was buggy and twitchy. So I re-enabled speedstep.

 

[fagetti]

Was processor on stock settings? Did you check laptop ports for shorting? Did you try memtest? Windows restore point? Updating bios? download crystaldiskinfo and what is your ssd / hdd status?

 

[fagetti]

What is your bios version btw, you can see it entering bios

 

[fagetti]

Go to bios and see there option "CPU Performance mode" enable it and try again
