Lag with video games

Hi all, I really like the new operating system alot, but I've never had a problem with my games like this before. All my video games either steam related or other. I'd start up my game and for seven minutes or so they run fine, normal fps for my copmuter and what I've always had, then after eight minutes of playing I get very low fps and lag for ten seconds maybe every twenty seconds. I've done what I've read in a nother thread, switched to an earlier combatibility and disable those two features and run as administrator. Nothing has worked and I'd like a solution please.
Thanks for your help.

Nvidia Geforce 9400M G

Anything else?

What exactly did you try in another thread?

Pinstripe posted this fix, which has worked wonders for many:

Leave the multimedia class scheduler service running, but disable its network throttling "feature":

• Open regedit
• Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
• There will be an entry for network performance throttling, default value is 10; set it to FFFFFFFF hex (willl look like 0xFFFFFFFF to the right of the entry)
• Reboot

Umm that didn't work, it was a thread that read FPS is horrible for offline games

Anyone know?

I've done what I've read in a nother thread, switched to an earlier combatibility and disable those two features and run as administrator.

I'm still waiting to hear what exactly you did and with what settings the machine has now? It does not sound like an overwhelming problem, but we've got to know our starting point... so tell us.

Hmm ok well I switch combatablilty on my games to Windows Vista service pack two since I had Vista, and checked off run as admin and disable visual themes and disable desktop composition.

Are these older or newer games? Have you tried running them in XP compatibility mode?
