When I try and play COD4 MP it's very laggy, no matter what the ping of the server or how many players are in the game. Even on the menu the mouse jumps around the screen. I have turned down all gfx settings to minimum to no avail. I have minimal background programs running. SP is great, I can run it clean on decent settings but MP is a no go.
relevant PC specs:
I run it through Steam. (That's where I bought it.) Never had this problem with HL2, which runs fine online on Steam.
Did a speakeasy speed test and my connection is around 580 d/l and 280 u/l. That should be enough, shouldn't it? Is Steam the problem? I would think my PC should be able to handle this. Thanks for any help
This is an update for users that may read this with similar problems:
I ran into slowdowns again the other night, so offline in steam wasn't the problem. I NOW believe the problem is PunkBuster, and I got it working again by manually updating Punkbuster via their website and the pbsetup utility.
This has now happened a few times where I join a server and its choppy, and the solution I've come to is choppiness= Punkbuster needs to be updated. If I close CoD4, update PB, restart, open CoD4 MP, it's fine. Don't know why restarting works but when I update PB and run CoD4 its still choppy. (And just restarting w/out updating doesn't work).
I still am not positive what the deal is as that seems to be a rather odd solution, but as I said earlier if you are reading this and having similar problems try the above.
