Go here for helpful console commands which includes a config editor tool if you are not comfortable changing the settings yourself:

Frag World

Please understand that you have two types of lag in a First Person Shooter, video lag and packet/internet lag. Your goal is to have at least 60 FPS, if you run the FPS meter in game you will notice it changes color, it has been this way since CoD 1, anything in red means that your video is lagging, this is why you are getting shot and not getting a shot off or some one is getting you around a corner faster than you can react.

FPS Lag:

The biggest hit to FPS that can be changed via the game are shadows, everything in this game makes a shadow, if your rig can't get to 60 FPS with them on, turn them off. Set everything in the graphics area to a setting, do not leave anything in auto and turn off Vsync.

Use the config editor, the console commands or edit your config file to remove other FPS hits that are mentioned at Frag World.

Update your drivers!  Nvidia drivers are at 260.99 at the time of this post, if you are using 260.89 get rid them ASAP, they were junk and caused BSoD for me. I have not had a crash or stutter with the 260.99.

The 60 FPS debate still rages, think of it this way, you are running at 60 FPS (the highest the human eye can see) and the other guy is running at 25 FPS, what happens? You react faster than him, push the mouse button to create the input for your gun to shoot before he can maybe even see you and you win.

Packet Loss/Internet Lag:

Again, visit the above site to set you max packets.

Also visit Kilgore's post on our forums if you are running Windows 7 or Vista, in order to change your max packets in your OS, its default is 10, the change listed in the post will remove all restrictions.

Thanks Tuhoa, good stuff, most of this i've seen except for Kilgore's well written post.  Want to clarify' in win7 OS, I change '10' to 'FFFFFFF'?  What does it mean by 'in hexidecimal'?  The letter F is not hexideciaml

By default, the value for the NetworkThrottlingIndex registry entry is set to 10. When the NetworkThrottlingIndex registry entry does not exist, the behavior resembles the default behavior. Network throttling can be completely turned off by setting the value to FFFFFFFF (hexadecimal). You must restart the computer after you make a change to the value of the NetworkThrottlingIndex registry entry.

This value translates into a numeric, 4294967295.

Gotcha, thank you.  Ok, All Wise One   The other item perplexing to me is from Kilgore's post '*Forward your ports if you're behind a router: TCP [3074] UDP [3074]'  What is 'behind a router'?  What is port forwarding and why would I care?

Thanks for the info, my FPS went from 50's to 60's to 90 to 93 FPS, except for the Jungle map. It comes down to mid 40's to low 60's.

Great info thanks!

As ive stated in several posts pertaining to BC2 you ALWAYS nerf shadows / water when playing the multiplayer version of any game. If you want it to be pretty you best be running a killer rig;

As for the maximum frames per second the eye see's is actually false The human eye does not see in frames. It is actually just a receiver of light, its the brain that processes the images we receive.  To basically make it make sense, ill simplify it. After tons of tests done by many companies, the human brain seems to like a minimum of 60hz ( or in the monitor world that's our refresh rate IE: the most frames the monitor can produce without image tear ) to make a clear detailed image.

Some users don't like to see image tearing; some even say that it bothers them while playing. So if you want a fluent game play without image tearing keep vsync on. It will sync to whatever your maximum refresh rate is. ( most older models are set at 60 while newer monitors do 120 and even on up to 240 if your wanting to do 3D. ) Keep in mind though, if you enable vsync and have it set to sync to 60 make sure you card can handle 60+ without any problems.

Yes i do realize that movies/console games only do 30fps; They can do this by applying motion blur, plus a couple other things but that's to technical for a simple forum reply lol ;)

Simple rule of thumb; If your playing on the PC, you WANT 60+ fps at all times or else your giving others plays the advantage.

This is a good bit of information of BlackOps players. With some of our members still running cards older than the 8800's  their gonna need it

When he talks about forwarding your ports, he is making sure your router/firewall is not blocking the ports you need for the game to connect to the servers.

BUMP

/snd_restart has been a huge help for me.
I just do it every map load and it eliminates that sound/screen stutter.

When the NetworkThrottlingIndex registry entry does not exist, the behavior resembles the default behavior....
