Thread: Fixed My Stutter!! | Forums

  1. #1
    Hello All,

    I thought I'd post about how I solved a stutter issue with Lock-On. I stumbled upon an interesting problem with my Windows XP services due to an investigation into what was causing a 10 fps stutter every other second or so in Lock-On.

    At first I thought the stutter I was experiencing (drop from 32fps to 15-20fps, every second or so) was due to a sound issue like so many have reported. After turning down hardware acceleration I was still experiencing the issue.

    Next I made sure nothing was running on my pc that might cause LockOn to run slowly. I then came across my Software Firewall Sygate which was running, I noticed it was blocking network traffic. About every second or so. It turns out that the driver: ndisuio.sys was sending and trying to receive network traffic which was being blocked by my firewall. I thought this was interesting, so I disconnected my cable modem and ran Lock-On again. NO STUTTER! After further investigation I found this thread: http://www.iceteks.com/forums/index....opic=1290&st=0
    (see page 3)
    It turns out that ndisuio.sys is controlled by the Wireless Zero Config service in you local services. I disabled this service and the stutter ceased. The service is primarily for wireless routers and mice/bluetooth hardware.

    I hope this helps others who may have similar problems. Note: Activation of ndisuio.sys could be an indicator that svhost.exe has been compromised by a trojan/hacker, it is a good idea to install the windows xp security patch located here for this file vulnerability: http://www.microsoft.com/downloads/d...DisplayLang=en

    Note: if you do use wireless hardware, then you will need to keep this service running.

    My svhost.exe is still running. I was told removal of the file would screw up windows. But I'm not sure about disabling it, I haven't tried that. But disabling the Wireless service removed my stutter.. At least I haven't had an instance of it since disabling it.

    Here's an interesting comment from sygate tech supp: "You might try taking the server rights from svchost.exe. In the applications list you can highlight this service and click Advance and uncheck the "act as server". This will stop this services from listening.."

    as far as i know svchost.exe acts as a hostprocess for certain services and is as such part of windows.

    svhost.exe however could be part of a virus attack. read more here http://www.linkbyte.com/ubb/Forum6/HTML/000008.html
