I never had this lag problem before... I installed steam freshly and then installed NS 3.0 beta 1 when that was the only one out atm. And it played perfectly fine with no any lag at all. But the next day I got a cl_dll.dll error saying that it was differ from the server, so I copied the cl_dll.dll from my bro's comp which worked perfectly fine. But now when I play I get lag when an enemy is in my sight, after about 5 enemys in my sight my ping goes all the way up to 500+. So I uninstalled Steam and deleted all the registry keys related to ns and steam then did a fresh install with beta 2; however, it continues to lag whenever an enemy is in site. Any ideas? And thanks in advanced.
