Windows 7: "lag" in online games with Windows 7

Guys I just figured out my issue and unfortunately it has nothing to do with anything you guys discussed here. CPU heat sink and fan got unseated and needed to be reapplied. As a result the heated up CPU was running at 60% of its core speed which was killing all my performance.



If you think this might be happening to you, download CPU-Z and make sure your CPU is running at the speed you think it should be. Thanks for all of the help and good luck with everyone else looking into this issue.

how fix this in Windows 7 Ultimate x64?

If we knew how to fix this issue, this thread would be useless (or closed).
I've tried everything described here on my Win 7 Ultimate x64 installation with no success at all. Some people found issues causing the lag but those we're working for them and few others but not for all of us. There is no universal solution. You have to read the thread and try all of the advice that were given here.

If You already tried all of those methods to no avail then You can only wait for Microsoft to get it done properly.

Update: I updated my sound driver directly from realtek instead of MSI's version and now it work's with the fixes. The problem may have been that the MSI driver was 32Bit.

Hello!

My current system spec is in my profile. (Windows 7 X64 Ultimate)

The game in having problem with is Team Fortress 2 and L4D2.
L4D1 works fine as does Assassins Creed 2: Brotherhood on Steam.

Iv'e tried both the fixes and none work.
(FFFFFFFF, FFFFFF, dec 50, 1000, 100000) with MMCSS on or off. Rebooting after each property change.

Turning MMCSS off only made the audio stutter but not removing the lag spikes.

Tried turning Aero off / Using Windows Classic Theme.

When i disabled the audio in the device manager the lag spikes stopped.

The problems started when i upgraded to my new specs from a Intel Core 2 Quad Q8200 2,33GHz, on a Asus P5Q, P45, Socket-775, DDR2.

I would appreciate any help i can get.

If someone could verify this for me it would be great. I set the throttle value to five [dec] and my spike went away. I dont know why, but it worked. If it works for anyone else please say

Being a member of MSDN, I downloaded 7 ULT. 64 with SP1, did a clean wipe/install. Updated windows and installed only Nvidia and razor drivers, used MS's drivers for everything else and my problems are gone. I get no stutter anymore.

I also disabled eist in bios per gigabytes suggestion to lower dpc latency.

EIST?? Which is? And how do you lower in giga bios. X58 UD3a MB.
