Lately it has come to my attention that there are some serious gaming flaws in Windows 7 that have carried over from Vista. On more than one occasion I've ran into slightly older hardware that would warp, skip, lag and in general have low frame rates.

These games include: Source Engine Games (Team Fortress 2 (TF2), Left 4 Dead, Left 4 Dead 2, Counter Strike Source (CS:S, CSS)) Heroes of Newerth (HoN) Call of Duty Series (CoD), Modern Warfare, Overlord Series (Overlord, Overlord: Raising Hell, Overlord 2) and a lot of Valve games.

As an example, COD:MW2 players have told me that they have choppy game play and all of them wanted to know if there was something they could tweak to make the game run faster without having to upgrade hardware. I was aware that the game needs over 2GB of memory for extra settings. If they adjust the settings to "Normal" they typically can play the game just fine.

If however you can play Crysis @ max and yet MW2 is choppy. Then I'm pleased to let you know there may still be some hope left! It was easy to blame IW for making a PC Port, because it is. Nonetheless the real problem falls back with Microsoft Windows 7 and how it handles network throttling, audio issues and the "Multimedia Class Scheduler" service.

Try this fix provided by pinstripe before buying new hardware!

Quote:

  • 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 (will look like 0xFFFFFFFF to the right of the entry)
  • Reboot

Yep, granted a 3850 AGP is not the fastest card on the planet. I expected the card to at least run COD:MW2 if even at low settings. Running the game at 1280x1024 and everything normal did give me around 30 to 85 FPS. The problem was however that even at 85 FPS there was this stuttering effect that would have you scratching heads compared to other games. While running the built in windows monitoring software I could see that the CPU was hardly touched. This puzzled me because this throttling issue is normally associated with processor. The only thing that was near max was the memory using  a min of 90% of the 2GB. Granted that AGP is a bottleneck, I was still dealing with a Core 2 Duo processor. 

On that Website link above, the first fix was this:

  • Stop and disable the "Multimedia Class Scheduler" service
  • Run regedit and go to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Audiosrv"
  • Double click on the entry "DependOnService" and delete the line with "MMCSS" from the text box
  • Reboot and enjoy lag free games

This however did not help me and I was about to give up having exhausted all avenues. And so I read the update and the idea came to me. I tried turning off the onboard audio, same problem. Then removed the SB card and tried the onboard audio, same problem. I was expecting nothing to work and just out of curiosity after having regedit already open to put back the first fix, I then tried the network performance throttling.

  • 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

It works! It works! cheeky

There was a few minutes after this fix that I ran into a another problem of my own design. Suddenly I was aware of the audio being reversed. It was odd I was hearing sounds behind me and yet no one was there? Turns out my cheap speakers had been mixed with left and right on the wrong sides. Duh!

It still has those moments of lag if I turn or run too fast as to be expected with older gear, but at least we know the real problem now and the hardware can work at full speed if even a new card is still needed.

There are some systems that stutter and chop for no reason in only these games and most are greatly improved with this fix. Test it out, if it works or has no effect let us know.
