So I have always wanted to play DM, it just cost to much so I never bought it. Like 3 days ago I saw it was on steam for 10 bucks so I Downloaded it.

I played the singal player version fine, no lag eveything on high, then I tried the muti player version and it was laggy. I turned everything down for the muti version and it was still laggy, I died and when I repoped there was massive lag. Now any game on my comp I play lags so bad I can hardly play it, I have never had this problem befor and have to asume it because of teh DM game, I can't seem to fix it by re isnatlling new drivers or anything.

Anyone else having problems like this?

Make sure you have the latest version of Steam. Many problems arise from an old Steam installation with new games on it.
Back up your games. Completely uninstall Steam. Reinstall from the latest Steam Installer, see this page, follow link "Get Steam Now".

Also make sure you have a cabled broadband connection. Firewall configured to allow the game, or firewall down (if only to test).

Thank you, do you know why it would be lagging all my games tho, Everquest and everything? on my task manager I sit at around 30% CPS use now.

It effects games and programs outside of steam.
