I've had this problem years ago and I have it today.

I reinstalled Raven Shield, patched it to 1.60. I made a LAN game. As soon as I start the server, it freezes for a few seconds, goes back to normal, then a few seconds later it freezes again. It keeps doing it and I have no Idea why.

I doubt my hardware has anything to do with it because we changed our computers since last time.

Windows XP SP2
AMD Athlon 64 3000+
ATI Radeon 1600 XT
1 gb ram

Punkbuster is off.

PB needs to be disabled on the server and each client connecting to the server. If any client has it on, they will freeze like that.
