Windows 7 Game Performance

I agree with ZeesuS, if you did an upgrade you killed your computer. Clean install it.

I could also recommend to use cleaning programs such as Ccleaner, advanced system care, which cleans a lot of crap that has your computer. After that, you should defrag your disk so it can perform faster and better (I would recommend Auslogic Disk Defrag).

If none of that help you can either try Game Booster Ver 1.3 (NOT BELOW) or TuneUp uitilities 2010 Turbo Mode (Trial 30 days)- Which temporarily kills the Aero Scheme and some services that you don't use while on games.

As final recommendation, try to play without the use of background programs which sometimes may be the cause of that laginess and remember that XP was lighter than 7 and Vista. Plus, remember the game you are playing on Win 7 has direct x10 as a default, and on XP it was DX9, so, DX10 is a little heavier but much prettier and smoother, but DX9 is lighter but uglier and less smother.

I did a clean install. The singleplayer performs as well as XP so I don't know if it's some kind of network issue although I've disabled the Windows firewall. There is a possibility it is related to punkbuster, the game authentication software, but other games that use it work fine so I don't know.

Hi.
Usually services slow down the process. Try disabling some services that you don't need. You should see a little difference.

I can really try to optimize performance, but there seems to be a fundamental problem that causes the game to be excessively jerky.

I just tried joined a non-punkbuster server and it was no help.

The problem I've been having with Frontlines and other games to a lesser extent is due to some of the game data being swapped to/from disk. I have two gigs of RAM which should be sufficient for these games, but I am forced to turn off the page file to get acceptable performance. I don't know enough about the paging algorithm used in Windows 7, but I'd like to get the best performance without disabling the page file. I don't see why this should be an issue really, shouldn't anything not being used at the moment be swapped to disk to the give the largest amount of RAM to the process that needs it most? Any ideas?

I'd also consider installing more Ram..I assume your motherboard will support it...your system specs are ummm none existent but most motherboards these days support dual channel.
