XP and laggy mouse tracking



I'm running XP and trying to play q2 and CS. Every 4 seconds or so my mouse lags (stops tracking) and then kicks in. It's worse when I move my mouse while I'm hooked on something in q2. Does anyone know how to fix it? I've already tried tweaking the IOPageLockLimit (http://www.xp-erience.org/sections.php?op=viewarticle&artid=14#mem) setting in the registry and no luck. I've read on messageboards that this cures it but it still won't work for me.


It is strange , I have quake 2 running quite good here


try this Read me

there are console commands but im damned if i can remember them


I had the same problem when I had zonealarm loaded - it improved when I re-installed the firewall .
Hope this helps - TTFN SPIT.


It would help if you would state which mouse and drivers you are using.

My son had a problem with his mouse. It was the Microsoft Optical. It was an older one. He then got the new Microsoft Explorer 3.0 which is a lot faster (taking like 6000 pictures a second). Fixed his problem.

Also that p2rate program thing is unnecessary. Those settings are already in XP to adjust in the mouse properties.

You might want to turn off your Firewall. When I ran ZA I would loose mouse control just as you discribed. ZA messed with my mouse. If you are running Zone Alarm. Turn it off and see if thats the problem. IF that is the problem, ZA website in their FAQ address's the problem so I would look there also. I finally deleted my ZA and went with Tinys Firewall www.tinysoftware.com

You have this command added noforcemparms -noforcemaccel correct? If not, add it.

Hey EP! All good with me, applying for Microsoft MVP right now, should have done this a while ago.

Notifications don't work, I only found your response by coming back to hunt up some threads, if you want, give me your email address so we can keep in touch easier!

EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there!
