Things seem to run smoother, but it feels like there are still some lag problems. But that might just be me since I am not a great player.

Then again, a patch is only as good as the gameplay. And right now there are just too many run and gunners for it to be enjoyable. Also it needs better maps.

Tools my friends.... tools.

Hi Samuel033

If you need a good blackops server, my clan is running a good server. I can pm it to you if you wish. It is a tactical realism server. Search and Destroy only though.
